I’ll admit, climbing is not my favourite part of a ride, but when you get a bike that climbs like Trek’s new Fuel EX, cranking uphill gets a lot more enjoyable! The 2023 Fuel EX will serve as Trek’s mid-travel do-everything trail bike, and it offers a near perfect ‘quiver-killer’ package with its aggressive climbing ability, slack steering angle and 140/150mm travel. Add adjustable geometry and shock progressivity to that, and you’ve got one versatile trail machine.

I picked up the Fuel EX 9.9 XX1 AXS during Crankworx Whistler, giving me a few weeks to get a handful of rides on it. Right away I can say the bike climbs like a hyperactive goat, but my area demands a bike that can descend well too. The Fuel EXs steering angle is slack enough for any trail, so the bike only finds its limit on really rough terrain that challenges its 140mms of rear travel.

2023 Trek Fuel EX – basic specs:

In this article we’ll discuss how the new Fuel EX rides. Here’s few basic specs, but check out my launch post for all the details on the new Fuel EX’s features, geometry and build kit options.

The Fuel EX frames are offered in both aluminum or carbon, with 140mm rear travel and a 150mm fork (except the entry level EX 5 which carries over the outgoing frame with 130mm travel). Most sizes ride on 29” wheels, but the XS frames run 27.5” only and the smalls offer the option of 27.5” or 29”. The 29ers can be converted to mullet setups, but Trek recommends adding a 160mm fork.

Between Trek’s Mino Link chip and optional angle adjust headset cups for the Fuel EX, there’s plenty of variation in frame geometry depending on settings. Some angles and measurements change with frame size as well, particularly the rear end lengths which are now size-specific.

To summarize it quickly, the Fuel EX’s head tube angle can range from 63.5° to 66° with the optional cups in play. Without the cups, the Mino Link gives you the choice of 64.5 or 65°. Seat masts are pretty steep at 76 to 78.9° across all sizes/settings.

Trek stretched out some pretty lengthy reaches on the Fuel EXs; The M/L bike I’m testing measures 470mm. Out back, Trek leaned towards the middle with their new size-specific chainstay lengths. The M/L frame I rode has 440mm stays, which are not short but not long either.

The top-of-the-line Fuel EX 9.9 XX1 AX S weighs 32.76lbs (with pedals).

Ride Impressions: Suspension

I am quite familiar with Trek’s suspension, as I’ve owned a Remedy for the last few years. I wasn’t surprised to find the Fuel EX climbs even better, and offers about 95% of the Remedy’s downhill prowess.

Trek’s ABP linkage is a very supportive climber, especially with the rear shock in its firm position. With the shock’s help, the rear end firms up enough that the rear wheel starts floating over pockets between roots and rocks, rather than diving into them. You’ll still use about 50% of the rear travel on singletrack trails in firm mode, so I still find traction is ample and the ride remains fairly comfortable.

What’s great is how the Fuel EX is a solid climber without any help from the shock too. Climbing technical singletrack in open mode, I only dipped into 2-3mms more travel than climbing in firm mode. The ride does get a bit more forgiving and slightly more grippy in open mode (without losing much efficiency), so it’s a practical option for rougher ascents.

Somehow, despite how supportive the Fuel EX’s ABP linkage is going uphill, it’s a whole different beast going down. It’s as if the linkage is speed-sensitive, as it responds very well to all kinds of high-speed impacts and has an impressive ability to round off sharp hits. Whether it’s small chatter or a full-on rock garden, the Fuel EX smooths out the trail very nicely. The rear wheel always feels well planted, and the linkage gives the bike a plowy feel through rough terrain. I do find Trek’s bikes aren’t super poppy on jumps, but they do have ample mid-stroke support to pump well through rollers and berms.

I have some delightfully rough trails in my area of B.C. and I did find moments where more than 140mm travel would have been ideal! That said, I don’t think you could do much better with 140mms of suspension than the Fuel EX has. While it’s really the slack steering that allows this bike to tackle pretty serious terrain, the adjustable shock rate also raises this bike’s tolerance for fast, rough riding.

I had no trouble getting full travel from the bike in its more linear LESS mode, and being a lightweight rider this is the mode I’d keep the bike in. It was perfectly dialed – I was enjoying full travel on descents but not frequently thrashing the bike with harsh bottom-outs.

When I flipped the chip into MORE mode, it did make a noticeable difference to the ride, but didn’t have much effect on how much travel I was using. I expected the bike to feel stiffer than preferred and that I’d need a good hard hit to bottom out the bike with the added progression. Instead I wound up using all the bike’s travel on any typical descent, although there was a palpable difference in how the bike felt. I could tell the linkage was resisting hard, fast impacts more than before, so I’d bet fans of coil shocks, or heavier and more aggressive riders would appreciate the difference the chip makes. In my case, it just made the ride a bit firmer than it needed to be. If I was a competitive racer I’d probably prefer MORE mode, but I ride recreationally so I keep things on the soft side!

Fit-wise, the first thing I noticed about the Fuel EX is its generous reach. At 470mm on the M/L frame, it’s about the longest bike I’ve ridden yet. This nearly straightens my arms, so I don’t think I’d want to go any longer, but it did feel roomy and comfortable on the trails. Of course the steep 77.5 degree seat mast leans you over that lengthy front end, so you wind up well centered between the wheels.

I liked the 440mm chainstay length on the M/L Fuel EX. It’s not so long that the bike feels like an enduro sled, but it is long enough to provide a stable ride and great climbing traction on steep uphill sections.

I am also a fan of slack steering angles. I didn’t have the optional headset cups for the Fuel EX so I couldn’t go to 63.5°, but my demo bike was set up at 64.5°. That’s a great number for rowdy trails, and definitely allows this mid-travel bike to take on enduro-level terrain. I have not found running a slack steering angle causes any real penalty on climbs, so I’m happy with a slack trail bike.

The Fuel EX comes with the Mino link in Low position, which is definitely the preferred setting for my local terrain. The BB does ride pretty low in this position at 335mm, but I must be getting used to low BB’s because I didn’t have any problem with pedal strikes on this bike.

Standover height on the Fuel EX is not particularly low, but not problematic for me. If I wound up near the head tube I could damage some sensitive bits, but in front of the saddle there’s ample clearance for standing comfortably.

On-Bike Tools and Storage:

In recent years, Trek has jumped on board with on-bike storage and tools. The Fuel EX, in either aluminum or carbon, offers a frame storage compartment in the down tube. The included Bontrager BITS tool roll is designed to hold a tube, co2 canisters, an inflator head and tire levers.

The high-end Fuel EX 9.9s also come with tools in the steerer tube. The Bontrager tool offers a chainbreaker, and a removable multi-tool with seven allen keys, a torx and a flathead screwdriver bit.

Components:

The Fuel EX 9.9 XX1 AXS boasts a pretty top-of-the-line build kit, and gave me my first experience with SRAM’s AXS electronic drivetrain. I really like the feel and ergonomics of SRAM’s dropper post and shifter remotes, as the light push-button action is undeniably easier than throwing paddles on a traditional cable shifter. Performance-wise, the AXS drivetrain was great but not perfect – about once on every ride I’d get a bit of a hesitation when shifting (not always the same gear), and once the derailleur harshly jumped back into a gear after I rode a rough downhill section. Otherwise, the shifting was quick and precise, so for my short test I didn’t attempt to reconfigure the shifting. I had no real mechanical issues with any of the AXS components on my rides.

Aside from the XX1 AXS drivetrain I’d say it’s the one-piece handlebar/stem that gives the top-tier Fuel EX a really high performance look. The Bontrager RSL bar/stem offers a 27.5mm rise, 820mm stock width, and a 45mm stem length with zero rise.

SRAM’s Code RSC brakes offered ample power for any descent, but I was a bit surprised to feel how much squeeze they required to get full braking force. Of course, their modulation is great but compared to the TRP DH-R EVO’s I’ve been riding the Code RSC’s required more effort to almost lock up a wheel.

When I picked up the Fuel EX Trek’s people had it all set up for me, and I didn’t have to touch any adjustments on the fork or rear shock throughout my testing. Not surprisingly, the top-notch Fox Factory 36 EVOL fork with its Grip 2 damper left me nothing to complain about, as did the Fox Factory Float X rear shock.

Bontrager’s Line Pro 30 carbon wheelset offered that pleasant, slightly damped feeling carbon rims can provide, and survived my testing with no damage to speak of. The Bontrager SE5 Team Issue tires don’t match Maxxis’ Minions or Assegais in terms of overall grip, but they’re still fairly good for traction and they’re a fast rolling tire. To make sure you can get those wheels moving over anything, the Fuel EX 9.9 XX1 AXS comes with a small 30t front chainring and a 10-52t rear cassette.

I had no comfort issues with the Bontrager Arvada saddle, and no other mechanical concerns with any other components.

I’ve described how well the Trek is set up for all-around trail riding, but one thing I really appreciate is the relatively low weight of the Fuel EX 9.9 XX1 AXS. I’m a small guy, so I find lighter bikes a pleasure to climb, as they’re easy to heave up over bumps and power up steep sections. I’d bet Trek could have gone even lighter, but probably not with all the functionality plus the bells and whistles this bike includes.

The Fuel EX 9.9 XX1 AXS retails for $10,749.99 .

I rode a lower end version of this bike ( 9.7?) earlier this year in Moab, and I was equally impressed. I called it a hero bike because I rode like I’ve never ridden before – my grey haired friends amazed to see me going off 5+ foot drops and riding past them when they got off to walk ( both up and down!).

The yellow is absolutely terrible. It looks like a GT. Seems like a great bike nothing but positive things to say. Good job Trek

I hope this signals a reduction the “TREK” logo size across their bike line-up. Some of the high end trek road bike have embarrassingly large logos.

32+ lbs for the very top spec seems a little heavy? Otherwise it sounds like a great trail bike.

The Fuel EX 8 (aluminium frame) has put on 1.8 kg, which seems crazy.

Nice review, Steve. While you’re at one end of the travel needs spectrum, I’m at the other, trying to figure out whether I really need a bike with this much travel.

Love the yellow. So tired of Boring Black…..

Looks like Trek outsourced frame design to Astro. A definite step backwards in aesthetics. Hopefully the bike rides much better than how awful it looks.

I am definitely out of touch with today’s standards of what’s light and what climbs well

Have Trek given up on the through shaft damper? I have an 2018 Fuel Ex which I love, wondering if it’s now obsolete.

I hope they have

I noticed that they shortened the crank arms on the larger sizes to 170mm

FIRST RIDE REVIEW

The new trek fuel ex review.

Photos & Words by Dario DiGiulio

As mountain biking has evolved into what it is today, the trails we ride on have slowly but surely raised the bar of what modern bikes have to keep up with. Sure, some tracks have been sanitized over time, but there’s no question that the pointy end of the sport has kept pushing forward. As a result, trail bikes have had to pick up the pace to match the expectations of the average rider, leading to more capable and confident rigs with every new model. Stepping up to the plate, we have the evolved version of the Trek Fuel EX, Trek’s mainstay trail bike. This time it’s really meant to do it all, riding anywhere and doing anything. Being this adaptable can be a tricky task though, so has Trek painted themselves into a corner?

The new Trek Fuel EX breaks just about every mold that the prior generations had fit into, with a full-on redesign for the new model. The name of the game here is adaptability, whether in the geometry, the suspension kinematics, or even what size wheels you’ll run. Thanks to their Mino Link flip chip and two sets of press-in headset cups, you can shift the character of this bike drastically to suit your terrain and preference. As a result, it’s a bit hard to parse out the specific geometry of the bike (however Trek’s site features a geometry tool to let you do so), so I’ll just speak to it in its most neutral form, which is where many will likely settle. There are a whopping 8 size variations to this bike from XS to XXL, so it’s worth digging through the geometry tables to see which might suit you best. They’re all sporting 140mm of rear travel with a 150mm fork, upping the numbers on the prior generation by 10mm.

I’ve been testing the large frame, which puts the reach and stack at around 485mm and 621mm, which are in line with the majority of the industry right now. In keeping with the new Trek Fuel EX’s theme of being adaptable and capable. In its neutral-low setting, the bike comes with a 64.5-degree head tube angle and the effective seat tube angle sits at 77.2-degrees. Chainstays shift with the frame size, and on a large come in at 440mm. Thanks to the Mino Link flip chip, you can adjust bottom bracket height by 8mm up from the slammed 38mm drop in stock configuration, with a 0.6° steeper head tube and seat tube angle. The more significant head tube adjustment comes from the independent press-in headset cups that Trek supplies, which can steepen or slacken things by a full degree, giving a very wide range of handling characteristics. The last frame toggle is the progression flip chip, offering a simple more or less option to tailor the suspension feel and offer uncompromised coil shock compatibility.

As is trend right now, you can set the Fuel Ex up as a mullet, simply by popping a 27.5” wheel in the rear, swapping the Mino Link to high mode, and bumping up fork travel to 160mm. The bike comes stock as a 29er front and rear (or 27.5″ in XS and Small), so you’ll have to make this change on your own accord.

A notable thing lacking from the newest Fuel EX its the Knock Block – you’ll find no such thing on this frame. X-up fans take note, as this is a big move for the engineers in Waterloo, Wisconsin, and was necessary to achieve the headset adjustment range they wanted. Trek has also moved away from the RE:aktiv damper shock, now simply relying on an off-the-shelf model. Still included in the frames are the handy-dandy stash box in the down tube, with what I think might be the best weather sealing of any of the options on the market at this point, and a neat BITS tool roll.

Build kits come in as many flavors as the sizes, and the range of options is quite extensive, beginning at a respectable $3,699. I’ve been on the highest end build, the 9.9 AXS especial, coming in at a healthy $10,749. From Bontrager Line 30 carbon wheels, to the RSL one-piece carbon cockpit, to the XX1 drivetrain, just about everything is as nice as it gets, as you’d hope for this kind of money.

At my height of 6’3”, the geo combination of the Neutral-Low-More flip chip configuration on the large size makes for a really comfortable fit,  one that feels stable enough at speed while still remaining lively for your average trail. I started my time testing the bright yellow Trek up in Whistler, riding some gnarly rocky pedal-access trails around the Valley. This was a great context for deciding where I stood on the less or more progression debate, and I settled on the latter end of the spectrum. Increased bottom-out resistance and a more supple top of travel were worth a slightly punchier suspension feel, and I stand by that choice for most of the riding I have around me. On my home trails in Bellingham, the Fuel has been a choice companion for fast and fun rides in our local trail systems, where technical and engaging climbs lead to fast, rooty, and jump-filled descents. My general synopsis is that this is a bike that loves to ride fast, both up and down.

The climbing characteristics are comfortable and neutral, without wallowing too much or lacking grip in trickier terrain. Like many of the take-aways of the bike as it comes stock, things are extra-medium, in the best way. Compared to the new Hightower, the bike has slightly less support, but is significantly better in rough terrain and successive hits. Compared to the Stumpjumper EVO, the Fuel EX is definitely more of a trail bike, less of the all-mountain enduro-lite ride that the Specialized offers. All three bikes serve as a nice gradient from the lighter and sportier end of the trail spectrum to the burlier and more capable side of the category. Sitting pretty right in the middle is the Fuel EX, but I’m sure one could tweak it to either of the other extremes, given how much variability is baked into this frame.

Build kit notes are mostly positive, which you’d hope to see from the highest end build. My main gripe is with the Bontrager SE5 tires, which are some the least confidence-inspiring I’ve ridden in recent memory. The casing and tread pattern are fine, but the compound doesn’t seem to want to hook up anywhere, whether it’s dry loose terrain, rock slabs, and especially wet roots. This would be an immediate swap in my book, and I’d just keep the stock tires to run in the rear when conditions are dry and beat at the peak of summer.

The removable shuttle pad doesn’t seem to want to stay close to the frame, and bows out slightly when attached, giving the downtime a funny bulged look to it. One other frame annoyance has been a recurring suspension knock, despite chasing through every bolt in the linkage with a torque wrench. I still have yet to find the culprit, but luckily it’s not very noticeable when riding.

As a system, I’ve been more than impressed by Trek’s work on the new Fuel EX. Not only does it feel quick and confidant in the stock configuration, it also offers a whole host of layout options to better cater the bike to your preferences.

THE WOLF’S FIRST IMPRESSION

To close out our review of the new Trek Fuel Ex, it’s clear that Trek’s engineers and designers set out to design a bike that caters to that wide center of the market – the trail bike – where most riders spend their time, and where a bike can take many forms. In that goal, they found success. Sure some riders may feel the new Fuel EX has departed from what they were used to and liked about the bike, but many other riders will likely welcome the advancements in capability and confidence on the trail. The Fuel EX is a highly adaptable bike that feels comfortable in a really wide variety of terrain but doesn’t confuse itself for anything more or less. Bike riders, rejoice.

"Fuel EXe's natural-feeling assist and stealthy good looks earned it a coveted spot on TIME's Best Inventions of 2023 list." From TIME. © 2023 TIME USA LLC All rights reserved. Used under license.

TQ HPR-50 is Pinkbike's Innovation of the Year

"That tiny harmonic pin ring drive unit is the golden goose of e-bike motors." Find out what Pinkbike had to say about the revolutionary motor at the heart of Fuel EXe.

Best All-Around

"Overall, the Trek Fuel EXe is a bike that ranked consistently well across the board when it came to performance on the trail. It does everything pretty darn well and would be a great jack of all trades lightweight eBike for those looking to have a mid-power eMTB for trail shredding fun."

2022 Gear of the Year

"This is the first time an e-bike has made my Gear of the Year list [...] in addition to being silent, the HPR50 motor feels frictionless while pedaling. The assistance comes on with a subtlety that makes it feel like you are a younger, fitter version of yourself with a tailwind at your back."

Editor's Choice

"The low-key, silent assist is just enough, keeping it riding like a real mountain bike but making the climbs less sucky. Don’t get me wrong, I love a good high-power eMTB, but I loved this bike, too. Trek’s Fuel EX’s handling is dialed, and this is merely an enhanced version of that. I tested the top model, but, fortunately, there are also mid-priced models that eschew some of the AirWiz(ardy) without giving up any of what makes this bike rad."

"Nothing comes close"

"Simply put, nothing comes close to the Fuel EXe when you paint the picture of the mountain bike experience as a whole."

"Probably going to be the most significant bike launched this decade"

"The Trek Fuel EXe is the bike (e or otherwise) that plenty of people have been waiting to see… Removes the final few issues that the e-curious crowd had."

"One of the best mountain bikes - powered or unpowered - I’ve recently ridden."

"The Fuel EXe is such a harmonious package that I got comfortable with it very quickly, and it wasn’t much longer before I was in love with this bike...I legitimately forgot that I was on an e-bike at times…it’s the most natural feeling motor I’ve yet ridden."

"We have to call it as we see it and the Trek Fuel EXe just elevated the eMTB game."

"The first impression was a unanimous 'Wow.' This is one of the few times that a bike exceeded expectations."

"Nothing less than a great leap forward for eMTBs"

"There are times when I am left amazed by something new and shiny, and that is the case with the Trek Fuel Exe...I might even go as far as to call it an engineering marvel."

Geometry — Low

Geometry — High

Will my bike have a curved top tube?

Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Arguably one of the all-time most popular bike models of any MTB on the planet, the ‘Fuel Ex’ has been at the peak of Trek’s MTB line-up for as long as anyone can remember and it has had no fewer than six major design overhauls during that time. Late last year Trek unveiled their newest reinvention of the ‘do it all trail bike’ which rolls out of the store boasting a ton of rider customisation features, including a choice of [...]

The new Gen 6, Fuel EX 9.8 is the burliest, most versatile, and most capable Fuel yet; truly up for whatever you want to ride. Trek completely redesigned...

Apr 2023 · Drew Rohde

While the new Trek Fuel EX may have alienated a few riders, it will no doubt be a welcome redesign for a lot more riders!

Fast, confident and ready to rock!

More capable than ever

Great downtube storage solution

Adjustable and versatile geometry options

Med/Large size

Bar/Stem combo

SE5 Tires in the wet

Some may not like the newer, burlier bike’s transition

Dec 2022 · Mike Levy

The downtube storage compartment is on the new bike, and while it seems like Trek has put all the things onto the latest Fuel EX, there's one that they didn't: Knock Block.

Wide range of effective geometry adjustments

Just as much fun on smooth trails as it is on scary trails

Great climber, efficient pedaling

One-piece handlebar might be too stiff for some riders

Paint chips easily

New geometry, more travel, and even better suspension improves Trek's mid-weight trail bike.

Sep 2022 · Guy Kesteven

More travel, longer, slacker and steeper, with extra adjustability and shock options. But how does Trek’s new trail all-rounder ride?

Superbly balanced adjustable geometry

Awesome suspension performance in ‘progressive’ mode

Poppy, playful and fast-climbing for its weight

Truly premium wireless, Fox Factory, carbon-loaded spec

Lifetime warranty, threaded BB and tunneled routing

Heavy for spec and travel

Costs more than parts sold separately

Default shock set-up is too linear

Headset adjustment is laborious

XX1 is fragile for aggro trail use

Sep 2022 · Tom Marvin

Does the benchmark trail bike retain its reputation as a solid choice?

Excellent suspension

Solid feel to the frame

Great geometry

Doesn’t feel as sprightly on climbs as some

Tyres give up corner traction too easily in loose or muddy conditions

Trek's top-tier Fuel EX 9.9 XX1 AXS delights on the climbs and tackles downhill terrain with it's slack (and very adjustable) geometry.

The Trek Fuel EX 9.9 X0 AXS T-Type – In our big 2024 trail bike group test

The latest rendition of a true classic. With the Fuel EX 9.9 X0 AXS T-Type, the American manufacturer introduces the latest generation of their trail veteran, which is intended to cover an even wider range of ​​applications, and can be perfectly adapted to your needs with many adjustment options. How does the concept work in practice?

The Trek Fuel EX 9.9 X0 AXS T-Type was conceived as a potent trail bike with a top-tier spec. It generates more travel than its predecessor, combining 150/140 mm at the front and rear, respectively. Retailing at € 9,499, the Fuel EX tips the scales at 14.9 kg and looks a lot like its electric counterpart, the Fuel EXe , which has already proven what it’s capable of in our light eMTB comparison test. The analogue Fuel EX model is available in seven sizes and offers countless adjustment options, both for the geometry and kinematics, making it an incredibly versatile bike.

For an overview of the test fleet head to the group test: The best trail bike 2024 – 15 of the most exciting trail bikes in our 2024 comparison test

The 2023 Trek Fuel EX 9.9 X0 AXS T-Type in detail

With its unmistakable frame silhouette and vertically-mounted shock, the Fuel EX 9.9 X0 AXS T-Type is distinctly recognisable as a Trek. The proprietary Active Braking Pivot rear suspension positions the rear axle inside the rear pivot bearing, which is meant to reduce the impact of braking on suspension performance. As usual, the cables are routed internally, running through the frame inside a sleeve, which makes it easier to work on the bike and replace the cables. The cables aren’t clamped at the ports, but don’t rattle on the trail. However, the brake line of the rear SRAM CODE Stealth brake slams against the handlebars and can’t be secured to the one-piece handlebar. A generously sized TPU ⁠plate on the down tube protects the frame against impacts and is complemented by an extensive chainstay protector. That said, when landing big drops and ploughing through rough trail sections, you can still hear the chain slapping against the frame. Of course, there’s also a storage compartment in the down tube – Trek were amongst the pioneers of on-bike stowage systems! The closure system is easy to use and seals tightly. The storage compartment comes standard with a small pouch where you can securely store all your trail essentials . Trek also hide a Bontrager multi-tool inside the steerer tube, which includes all of the basic tools for essential trailside repairs. Unfortunately, the tool makes a faint rattling noise on the trail, and while it’s not too bad, you still know that it’s there.

The spec of the 2023 Trek Fuel EX 9.9 X0 AXS T-Type

The Fuel EX 9.9 X0 AXS T-Type might not be the flagship model in the Fuel EX range, but it has a top spec. The FOX Factory suspension consists of a 36 mm GRIP2 fork and standard FLOAT X shock, which supercedes Trek’s proprietary Thru Shaft shock found on older previous models. The cables are routed internally, and run through the frame inside guide sleeves, which makes it easier to service the bike and replace the cables. The wireless, 170 mm RockShox Reverb AXS dropper post ensures lightning fast, butter smooth action. The American component colossus also supplies the CODE Silver Stealth brakes with tool-free bite point and lever reach adjustments. The levers also feature SRAM’s proprietary SwingLink technology, which was designed to minimise deadband and optimise modulation, thus reducing arm pump. The brakes are effectively identical to the Ultimate flagship model except for the carbon levers, and paired with a 200 mm rotor at the front and 180 mm disc at the rear. We would recommend upgrading to a 200 rotor at the rear to improve braking performance and modulation. The SRAM X0 Transmission rear derailleur is attached directly to the frame, forgoing both a mech hanger and the limit screws. Trek’s in-house, one-piece Bontrager RSL one-piece carbon cockpit consists of a 50 mm stem and 820 mm handlebars. These are far too wide, so we recommend cutting them to size. Moreover, the one-piece design doesn’t allow for fine tuning, except for the stack height, which can be adjusted with conventional round spacers – the cockpit on the SCOTT doesn’t even allow you to do that, with its proprietary spacers. The Fuel EX rolls on a Bontrager Line Pro 30 wheelset and Bontrager SE5 Team Issue tires front and rear, which are a perfect match for the bike’s intended use, providing predictable, controlled handling and adequate puncture protection.

How would you like it? The Trek is available in countless frame sizes and offers many adjustment options.

The geometry of the 2023 Trek Fuel EX

The Trek Fuel EX is available in a whopping seven, sizes XS to XXL, which includes an intermediate ML size. Reach values change in smaller intervals between sizes M, ML and L, which makes it easier to choose your frame size if you’re sitting on the fence. The smallest XS frame rolls on 27.5″ wheels and with size S you can choose between 27.5″ and 29″, while all other frames come standard with 29” wheels. The Fuel EX also features three different geometry adjustments: the Mino Link, which is essentially a flip chip in the seat stay, lets you switch between a high and a low setting. Another flip chip in the lower shock mount changes the rear suspension’s progression, making it compatible with a coil shock. Moreover, you can change the head tube angle between three different settings using different headset cups that can be purchased separately. If you fancy a mullet bike, the Fuel EX is a great option, as it can be converted to a mixed-wheel setup using a 160 mm fork and the low geometry setting. We mainly rode the bike in the low setting, with progressive rear suspension. Chainstay length is a moderate 440 mm in size L and grows with the frame size, with four different lengths serving the 7 different frame sizes.

The 2023 Trek Fuel EX 9.9 X0 AXS T-Type on the trail

When riding uphill, the Trek Fuel EX 9.9 X0 AXS T-Type places you in a comfortable, upright pedalling position, with the weight evenly distributed between the front and rear. However, on steep climbs, the front end becomes a little light, forcing you to actively weight the front wheel to keep it tracking. The suspension bobs noticeably, and as a result, climbs are more of a means to an end for the Trek, which doesn’t feel as lively as some of its competitors. On long, monotonous climbs, we recommend reaching for the climb switch to kill the pogo stick effect and get to the trailhead more efficiently.

On the trail, the Fuel EX impresses with predictable, balanced handling and strikes an excellent balance between agility and composure.

When gravity takes over, the Trek Fuel EX makes you feel at ease from the get-go, responding to steering inputs eagerly without feeling too nervous. The suspension is one of the Fuel EX’s true strengths, working discreetly in the background while simultaneously doing exactly what you want it to, without any unpleasant surprises. Even in the progressive setting with an air shock, the suspension responds sensitively and generates good traction, while at the same time providing plenty of support in the mid-stroke, allowing you to generate speed by pumping through flow trails and providing enough reserves to bail you out of botched landings without bottoming out. All in all, the Trek is very composed, providing a similar degree of stability as the Santa Cruz and Cannondale – though struggling to keep up with them in terms of agility. This becomes evident particularly in tight corners, where the Trek feels a little cumbersome – shortening the handlebars would help significantly here. Nevertheless, the Fuel EX is a strong all-rounder that performs well on a variety of trails and strikes a great balance between agility and composure.

Who should take a closer look at the 2023 Trek Fuel EX 9.9 X0 AXS T-Type?

The intuitive handling and excellent rear suspension make the Trek Fuel EX 9.9 X0 AXS T-Type suitable for a wide range of trails and riders. With its many geometry and kinematics adjustments, it’s also a good choice for those riders who love to play around with different setups to find their sweet spot. It’s easy and intuitive to ride, and delivers outstanding trail performance, whether you’re a beginner or seasoned trail veteran. The harmonious overall package is rounded off with clever frame details, like the well-designed storage compartment and integrated minitool.

CHARACTERISTICS

Value for money, intended use, cross country.

Our conclusions about about the 2023 Trek Fuel EX 9.9 X0 AXS T-Type

A perfect fit! With the Fuel EX 9.9 X0 AXS T-Type, Trek have created a bike for all tastes with clever frame features and countless adjustment options. It’s a strong all-rounder with easy, intuitive handling that strikes an excellent balance between agility and composure.

Mick & Wil review the Trek Fuel EXe

Following two years of development, the Trek Fuel EXe launches as a brand new electric mountain bike for 2023. Aiming to straddle the gap between the Rail (Trek’s full-powered, big travel e-MTB) and the regular Fuel EX, the Fuel EXe is built around a unique, never-before-seen motor that is claimed to be one of the quietest and lightest on the market. Along with its slim battery and carbon frame, the Fuel EXe is purported to weigh around 18kg in its lightest configuration, which is a good 5kg lighter than the Rail. That puts it into direct competition with the Specialized Levo SL and Orbea Rise ; two bikes that have had a significant head start in the lightweight e-MTB category. So what exactly does the new Trek Fuel EXe bring to the party? And how does its new motor perform on the trail? We’ve been testing it for the past few weeks to find out!

Watch our Trek Fuel EXe review here:

Overall it’s a very clean system, and combined with the compact motor and slim downtube, the Fuel EXe does a remarkable job of not looking like an e-MTB.

An overview of the Trek Fuel EXe

Whereas the Rail is based upon the Slash enduro bike, the Trek Fuel EXe is essentially an electrified version of the Fuel EX trail bike. It features 29in wheels, though it gets a touch more travel with a 150mm fork and 140mm of rear wheel travel courtesy of the ABP four-bar suspension platform.

OCLV Mountain carbon fibre has been employed to construct the Fuel EXe frame, while a two-piece alloy rocker link drives the rear shock via a trunnion bearing mount. Unlike the regular Fuel EX, Rail and Slash that feature Trek’s proprietary Thru Shaft damper, the Fuel EXe relies on a conventional rear shock.

The compact TQ motor

Powering the Trek Fuel EXe is a brand new and extremely compact motor that has been developed in collaboration with Bavarian company TQ.

TQ has previously been known for producing the 120Nm monster motor found within the Haibike Flyon. Taking the same patented Harmonic Pin-Ring (HPR) mechanism, those clever Germans have shrunken it right down to create what it believes is the lightest and smallest e-MTB motor on the market.

Comprised of just two moving parts, the HPR drive unit doesn’t require a belt or additional cogs, and it spins at an RPM that is three times lower than a conventional motor. Thanks to its simplified construction, the HPR design is claimed to result in fewer operating frequencies, reducing not only the overall decibels produced by the motor, but also lowering the ‘tonality’ (read: annoyance) of the sound.

Despite its compact form, the German-manufactured HPR50 motor delivers a healthy 50Nm of torque and a peak power output of 300W. TQ claims this motor has the highest torque density on the market, while offering seamless power delivery with virtually no lag.

It’s bloody light too

According to TQ, the HPR50 motor weighs just 1.85kg. That’s lighter than Specialized’s SL 1.1 motor (1.95kg), Fazua’s Ride 60 motor (2.3kg), Shimano’s EP8 (2.6kg) and Bosch’s Performance CX (2.79kg).

To make the most of its weight advantage, the HPR50 motor is paired to a modest 360Wh battery. This is claimed to weigh 1.83kg, which is notably lighter than the 360Wh battery used in the Orbea Rise (2.2kg), and about the same weight as the Specialized Levo SL’s smaller 320Wh battery (1.8kg). The compact battery allows the downtube to be made much slimmer, which results in further weight savings.

Putting the motor and battery together, here’s how the total system weight compares between the new Fuel EXe and its two main competitors;

• Trek Fuel EXe (50Nm motor & 360Wh battery) – 3.68kg 
• Specialized Levo SL (35Nm motor & 320Wh battery) – 3.75kg
• Orbea Rise (60Nm motor & 360Wh battery) – 4.8kg

Unlike the Levo SL and the Rise, the Fuel EXe’s battery can be easily removed from the frame without having to drop out the motor. This means you can charge it in the bike, or separately if you don’t have a power point in your shed. Trek claims you can fully charge the battery in just two hours with a fast charger.

Trek will also be offering a 160Wh Range Extender battery that customers can purchase separately for $1,199 AUD. Boosting range by a claimed 40%, the piggyback battery is designed to fit into a standard water bottle cage with the addition of a built-in retention strap for security. Unfortunately the Range Extender battery won’t be available in Australia until late 2022 however.

Tidy, integrated display

Just like the Specialized Levo and Rocky Mountain Altitude Powerplay , the Trek Fuel EXe features a display that’s integrated directly into the top tube. This 2in O-LED screen forms the control hub for the bike, with a single button that turns the system on and off. This same button is then used to cycle through four pages that display key metrics including battery status, riding speed, average speed, rider power, motor power, and estimated range. Because of its integrated display, the Fuel EXe doesn’t have room for the Knock Block steering limiter, and so omits it entirely.

A discreet two button controller sits next to the left-hand grip, allowing you to toggle between the Eco, Mid and High assist settings. Holding the top button also engages the Walk mode, which delivers power to the rear wheel when you’re off the bike and pushing uphill.

Bluetooth and ANT+ capability allows the TQ system to pair with your GPS head unit and mobile phone. Further functions can be unlocked via the Trek Central app, which offers navigation and integration with third party apps. You can use the app to tune the motor’s assistance levels, and it’ll also provide you with tyre and suspension pressure recommendations if you’re using a TireWiz and AirWiz.

Geometry & mullet capability

Without a bulky motor getting in the way, there are few compromises forced upon the suspension layout and geometry of the Trek Fuel EXe. For example, the chainstay length sits at an impressive 440mm, which is quite short given the 29in rear wheel and 2.5in tyre clearance. Trek has also chosen to stick with conventional Boost hub spacing and a 55mm chainline, so there’s nothing funky in terms of standards.

With the Mino Link flip chip set in the Low position, the Fuel EXe features a 64.7° head angle, a 76.7° seat angle and a 38.5mm BB drop. In the High position those angles steepen by 0.5° and the BB lifts by almost 7mm.

In that same High setting, Trek also states that the Fuel EXe can be run as a mullet with a 27.5in rear wheel. This will affect the motor’s output and 25km/h cutoff point however, as there’s currently no way for users to adjust the rear wheel circumference in the TQ system.

Trek Fuel EXe price & specs

Globally, there will be six Trek Fuel EXe models offered for 2023. Only three of those models will be available in Australia, with prices starting at $9,499 AUD for the Fuel EXe 9.5, and maxing out at $12,999 AUD for the Fuel EXe 9.8 XT.

All Fuel EXe models make use of the same TQ-HPR50 motor, 360Wh battery and OCLV carbon frame. There will be no alloy models for the foreseeable future.

The bike we’ve been testing is the top-end Fuel EXe 9.9 XX1 AXS, which in the States will come with a staggering retail price of $13,999 USD (that’s approximately $20,000 AUD!). It features RockShox Ultimate-level suspension, Bontrager Line Pro carbon wheels, a one-piece RSL carbon bar and stem, a SRAM XX1 AXS drivetrain, Code RSC brakes and a Reverb AXS dropper post. While this model won’t be available in Australia, aside from the wireless bits the spec isn’t drastically different from the 9.8 XT. As usual though, our review won’t be focussing a whole lot on the individual components, but rather the important stuff that’s shared throughout the range; the frame, handling, suspension and drive system.

Noise isn’t everything, but geez it’s nice when you’re on a quiet bike. And in this regard, the Fuel EXe sets a whole new benchmark that we expect other brands will attempt to follow over the coming few years.

Trek Fuel EXe sizing & fit

Deviating from the regular Fuel EX, which comes in six sizes, the Trek Fuel EXe will only be available in four. To suit our 175-178cm testers we chose the Medium, which features a 452mm reach.

We had few complaints with sizing, though the stock handlebars are comically wide at 820mm. Those were promptly chopped down to a more conventional 780mm width, which proved to be a better fit with the 45mm ‘virtual’ stem length.

While the big diameter seat tube is nice and short, the 150mm dropper post limited our freedom of movement when riding down steep descents and along jump trails. We’d prefer to see a 170-180mm dropper on a bike that’s as capable as this.

Otherwise the Fuel EXe cockpit is a comfortable place to be thanks to the agreeable Bontrager saddle and lock-on grips. The seat tube angle isn’t too steep, with neutral weight distribution that doesn’t put a load of pressure on your hands. There’s plenty of adjustability thanks to the long saddle rails for those who do want to shunt it forward for a more aggressive climbing position.

Where the Fuel EXe definitely feels like an e-MTB is in its Q-Factor. Although the TQ-HPR50 motor is very compact, the fat e*13 carbon crank arms see the pedalling width blow out considerably. We measured the Q-Factor at 195mm, which is wider than any other e-MTB we’ve tested, and around 20mm wider than a regular mountain bike. Many riders will be unfazed by the difference, and indeed the wider stance can improve your overall stability on the bike. However, flat pedal riders will need to be wary when riding through deep ruts, and those with sensitive knees may simply find the Q-Factor to be too wide for comfort.

Suspension setup

The rear shock on the Trek Fuel EXe is designed to be run with 30% sag, a process that’s made easy thanks to the anodised gradients on the RockShox Super Deluxe.

Jose Gonzalez of Trek’s Suspension Lab explained to us that the Fuel EXe does have a slightly lower leverage rate compared to the regular Fuel EX, and the rear shock has been valved with a medium compression tune. The aim here is to provide more support to handle the additional weight of the battery and motor. Because of the greater damping forces generated by the shock, we trended towards having the compression adjusters backed off from the neutral setting. High-speed was set at minus two clicks (fully open) and the low-speed dial was set at minus one click. Rebound was set a couple of clicks faster than halfway to suit our 68-75kg testers.

Up front is the new 2023 RockShox Lyrik that features the new DebonAir+ spring and Charger 3 damper. RockShox recommends an extra 10psi for this fork when it’s fitted to an e-MTB, but we found this pressure to be too high when paired with the highly supportive Charger 3 damper. We ended up running 10psi less than recommended on the chart, set the rebound on the faster side, ran the high-speed compression at minus one click, and set the low-speed adjuster a few clicks lighter than neutral.

Trek Fuel EXe weight

Confirmed weight for our Trek Fuel EXe XX1 AXS test bike is 18.6kg, weighed without pedals and with the tyres set up tubeless.

That’s an impressive weight for a full suspension e-MTB, especially when you factor in the aggressive Bontrager tyres, powerful brakes and piggyback shock. Still, it’s not quite as light as some of its competitors;

• Specialized Levo SL Expert – 17.84kg
• Orbea Rise M10 – 18.38kg
• Trek Fuel EXe XX1 AXS – 18.6kg
• Specialized Kenevo SL Expert – 19.12kg

When you consider that the Fuel EXe is the only bike in that list with carbon wheels and crank arms, as well as a one-piece cockpit, its weight becomes a little less impressive. Given that the Fuel EXe supposedly has the lightest drive system out of the lot, we suspect some of the additional weight is found in the frame itself. That’s no bad thing, especially if it equates to having a stiffer and more robust chassis.

What does the Trek Fuel EXe do well?

When riding the Trek Fuel EXe the first thing you notice, or more accurately don’t notice, is just how quiet the TQ-HPR50 motor is. No doubt about it, this is easily the quietest e-MTB we’ve ever ridden.

The overall decibel output is low, and the motor’s pitch is significantly less prominent than other motors we’ve ridden. Rather than droning or whining, the TQ-HPR50 motor emits a more discreet sound that’s a bit like a gentle breeze whistling through the trees. Furthermore, there’s no annoying clacking noise on the descents like you’ll find with the latest Shimano and Bosch drive units. The TQ motor does feature an integrated freewheel that allows the drive wheel to disengage from the cranks to minimise drag, but despite this we couldn’t detect any obvious noise when descending on rocky trails.

Indeed the motor and chassis are well damped, with very little vibration or rattling present. While riding back-to-back with our Canyon Spectral:ON test bike, which features a cavernous downtube and a Shimano EP8 motor, the difference in trail noise was stark. Noise isn’t everything, but geez it’s nice when you’re on a quiet bike. And in this regard, the Fuel EXe sets a whole new benchmark that we expect other brands will attempt to follow over the coming few years.

Initially the muted motor gave the illusion of providing us with less assistance. This is because the power delivery is less obvious than a louder, whinier motor. However, a glance at our average riding speeds had us soon correcting that illusion.

Of course there’s not as much punch compared to the bigger 85-90Nm motors on the market, which is to be expected. During our standardised range test (more on that below), climbing speeds aboard the Fuel EXe hovered around 14km/h, compared to 18km/h on an EP8-equipped bike. This means you’ll be working harder on the Fuel EXe if all your pals are riding on full-powered e-MTBs.

Still, if you only ever ride singletrack aboard your e-MTB in the Eco or Trail assist settings, the TQ motor is likely to meet your needs. This will especially be the case for lighter and fitter riders, who will find the 50Nm output to be just about perfect for trail riding.

Well-damped suspension & no-fuss handling

It isn’t just the motor that’s quiet either, with the Trek Fuel EXe delivering a nicely damped ride quality that’s complemented by the distinct lack of any slurping noises from the fork’s new Charger 3 damper.

The carbon chassis feels stout and reliable, with no hint of twisting or excessive flex under load. It somehow manages to achieve this sensation without feeling harsh or pingy, and instead offers an accommodating platform that allows you to push it quite hard without fear of being punished for less calculated line choices.

The top-notch suspension plays into this beautifully when you’re smashing down rowdy descents. The Lyrik’s mid-stroke is particularly good, offering a heap of support with plenty of big hit damping control that encourages you to let off the brakes when gravity takes over.

While the suspension is good, it’s worth acknowledging that the Fuel EXe is not as plush as the Rail. Along with its lower overall weight, it can’t monster-truck down wide-open terrain like the Rail can.

The Fuel EXe takes the upper hand as the trail gets squigglier though, with less exaggeration required from your handling inputs. The smaller and shorter battery puts less weight up towards the head tube, helping to centralise and lower the bike’s centre of mass. Combined with the stout frame, there’s very little understeer present with the Fuel EXe. Compared to bigger and heavier e-MTBs, it never feels like it’s trying to push wide or ride away from you.

The excellent handling and weight distribution makes the Fuel EXe an easier bike to ride for less experienced riders. For more advanced pilots, the Fuel EXe delivers a thoroughly involving ride quality. Yes it’s still an 18kg bike, but it’s far more playful than the heavier Rail, with the shorter chainstays helping to encourage front wheel popping shenanigans.

It dips into corners without requiring constant persuasion, and it takes to the air well too, maintaining a steady trajectory without making you feel like you’re an unwilling passenger. There’s a heap of support from the suspension for soaking up ill-timed landings when things do go awry, with the shock’s Hydraulic Bottom Out ramping up the travel in the final 20% of the stroke. While the O-ring indicated we’d used full travel on many occasions, not once were we able to detect it while riding.

What does it struggle with?

Though the progressive RockShox suspension on the Trek Fuel EXe offers bucketloads of high-speed control, it does feel quite aggressively damped on smaller chatter. This is more so the case with the new Lyrik, which hasn’t amazed us with its small-bump compliance, transmitting more feedback through to our hands.

The fork on our test bike has improved noticeably over the first dozen rides as the seals and bushings have bedded in, and there’s no denying the incredible support and control that the Charger 3 damper brings. However, the Fuel EXe hasn’t exactly delivered a cloud-like ride quality, certainly not compared to the floaty Spectral:ON we’ve been testing alongside it. For this reason, we’d be curious to try out the Fuel EXe 9.7 to see whether its Fox suspension package brings about a more supple ride.

We’ll point out that heavier and more aggressive riders may not encounter the same experience as us. And it has to be said that the damping support does make the Fuel EXe a highly responsive and rewarding bike to ride. Still, those eager for the cushiest ride on the chunkiest of terrain will likely be better served by the Rail.

Overall we’ve been impressed by the usable and natural-feeling support from the TQ-HPR50 motor. It doesn’t spike or surge, offering a nicely progressive power band that makes it predictable and easy to modulate on tricky climbs. The 25km/h cutoff point is about as seamless it gets, and because the motor is so quiet, it’s difficult to tell when the motor has disengaged from the cranks.

It took us a few rides to get used to though, as it can occasionally lag before the power starts to come on. Spinning a lower gear at a slightly higher cadence seems to be its preferred input, though we’ve not found it to be as adept at responding to rapid changes in RPM compared to some other e-MTB motors.

There are options to tune the TQ motor via the Trek Central app, which allows you to tweak the pedal response, assist factor and the maximum power of each of the three settings. Unfortunately the app hasn’t been available prior to the Fuel EXe’s public launch, so we’re yet to play around with those tuning options. We’ll be exploring more of that functionality over the coming weeks of riding.

What range can you get with the Trek Fuel EXe?

Depending on the terrain, most of our rides on the Trek Fuel EXe have typically racked up 1,000-1,300m of elevation gain over a distance of 30-38km. We’ve mostly utilised the Mid power setting, which strikes a nice balance for general trail riding.

It’s been mighty helpful having the battery status displayed as a percentage, and the remaining ride time and range estimations have proven to be surprisingly accurate. When you do get down to the final 10% on the battery, the motor’s power output automatically lowers a few notches to help conserve what’s left. It doesn’t totally limp home though, retaining a usable level of support all the way down to 0%. When you have finally cooked the goose, the lack of drag through the TQ motor means it’s not an awful experience to ride the Fuel EXe on human power alone.

To see how the Fuel EXe’s efficiency compares directly to some of the other e-MTBs we’ve reviewed, we subjected it to our standardised range test. This involves the same rider pedalling up a road climb with a 10% average grade, with the motor set to its most powerful setting, before bombing back down a singletrack descent. The idea is to see how much elevation, and how many laps each bike can rack up on a single charge, while keeping the variables as constant as possible.

Here’s how the Fuel EXe faired in our range test;

• Norco Sight VLT (Shimano EP8, 900Wh Battery) – 2,478m climbing (12.8 runs)
• Rocky Mountain Altitude Powerplay (Dyname 4.0, 720Wh Battery) – 2,108m climbing (10.9 runs)
• Cube Stereo Hybrid 160 (Bosch Gen 4, 625Wh Battery) – 1,800m climbing (9.3 runs)
• Canyon Spectral:ON (Shimano EP8, 630Wh Battery) – 1,570m climbing (8 runs)
• Orbea Rise (Shimano EP8-RS, 360Wh Battery) – 1,388m climbing (7.2 runs)
• Specialized Levo SL (SL 1.1, 320Wh Battery) – 1,377m climbing (7.1 runs)
• Trek Fuel EXe (TQ-HPR50, 360Wh Battery) – 1,312m climbing (6.8 runs)
• Specialized Kenevo SL (SL 1.1, 320Wh Battery) – 1,053m climbing (5.5 runs)

As you can tell by those figures, the Fuel EXe managed to achieve considerably more range than the Kenevo SL, and not just because it has a larger capacity battery. The Fuel EXe is also lighter, comes fitted with faster-rolling tyres and features a more efficient suspension platform.

It didn’t get quite as much as the Levo SL however, and there are reasons for that. The 35Nm output of the Levo SL’s motor is naturally less demanding in terms of its fuel requirements, since it delivers a slower average riding speed. This makes the Fuel EXe a noticeably quicker bike on the climbs, which isn’t accounted for in our range test data.

Given the Orbea Rise has the same capacity battery as the Fuel EXe and a more powerful motor on paper, how did it achieve more range? The simple explanation is the tyres. The Rise M10 we tested was fitted with a lighter and much faster rolling Maxxis Dissector and Rekon tyre combo, which likely accounts for the difference.

Of course it’d be possible to get more range out of the Fuel EXe by fitting lower profile tyres, and you can also utilise the lower assist settings to reduce power consumption. Once the Range Extender batteries are available, Fuel EXe owners will have the opportunity to boost range by up to 40%, which will see it get closer to some of those bigger capacity e-MTBs.

Component highs & lows

As mentioned earlier, we won’t be dwelling on the components of our Trek Fuel EXe 9.9 XX1 AXS test bike. And truth be told, there’s not a lot to be said about the ultra high-end build kit that we haven’t discussed before.

We’ve largely ignored the TireWiz and AirWiz gizmos to begin with, partly because we’ve been experimenting with tyre and suspension setup. However, we’ll be delving more into their functionality now that we have access to the Trek Central app that pairs with the sensors to provide live readings and recommendations.

It is worth touching on the new Bontrager SE5 tyres, which are spec’d on each Fuel EXe model. These 2.5in wide tyres feature a Minion DHR II-inspired tread pattern and a dual compound mix that combines a firmer 61a rubber in the centre tread, and softer 50a rubber for the cornering blocks. They’re built upon the Core Strength casing, which combines sidewall protection with a sub-tread reinforcement for puncture protection. The result is a solid, durable and well-damped tyre that isn’t overly stiff on the trail, while also feeling predictable across a broad range of surfaces. They’re decent all-rounders, though they aren’t as tacky as a Maxxis 3C compound or a Specialized T9 tyre. If this were our bike, we’d likely be fitting something softer up front for a little more bite.

There have been some mild annoyances on our test bike, like the rattling thru-axle lever at the rear dropout. Thankfully this lever can be removed, though you do lose its handy 6mm hex key. That didn’t matter too much as the fork’s steerer tube comes loaded with a Bontrager BITS multi-tool inside. The tool can be a bit tricky to remove, and we also found the bits have a habit of coming loose, allowing them to rattle around inside the steerer. Once tightened up, the Fuel EXe returned to its blissfully silent state.

We love how the TQ display sits flush with the top tube, though it’d be nice to see a clock offered on one of the data screens. The option to display cadence would also be useful, especially while getting accustomed to the TQ motor’s output. The controller offers a nice tactile platform with an audible, yet discreet ‘beep’ whenever you switch assist levels. However, accessing the Walk mode requires you to constantly press down the top button with your thumb, which is awkward when you’re holding onto the bars and pushing the bike up a steep and slippery incline.

Otherwise all the electrics on the Fuel EXe have proven to be totally functional. Being able to easily remove the battery will be a welcome feature for anyone who needs to charge it separately to where the bike is stored, and we like that the main charge port is located high up on the downtube where it’s protected by a thick rubber plug. Internally there’s also an automatic lock built into the main battery’s connector, basically eliminating any chance of the cable coming loose while bouncing down the trail. Sure they’re only small details, but they’re also clear signs of a well-considered design.

Trek Fuel EXe vs Specialized Levo SL vs Orbea Rise

Over the past year we’ve spent a load of time aboard two of the Trek Fuel EXe’s main rivals; the Specialized Levo SL and Orbea Rise. So how do these bikes compare?

Specialized Levo SL

Specialized launched the Levo SL at the start of 2020, which shows just how far behind Trek and most other brands have been. No, the Levo SL wasn’t the first lightweight e-MTB to hit the market, but it is the bike that has legitimised the category.

The Levo SL is built around the SL 1.1 motor, which you’ll also find in the Kenevo SL and the Creo e-Road bike. This motor dishes out 35Nm of peak torque, making it considerably less powerful compared to the TQ motor in the Fuel EXe. It’s also much noisier, emitting an annoyingly whiny pitch that takes a while for the rider to tune out. However, the SL 1.1 motor does offer more intuitive power delivery, and it’s also better at handling high-cadence pedalling spurts.

In terms of ride quality, the Levo SL delivers noticeably plusher and more active suspension performance, which makes it a comfortable bike to pedal over choppy terrain. It does have 10mm more travel at the rear, though the suspension kinematic and shock tune also feels lighter compared to the Fuel EXe. We have found it easier to bottom out the Levo SL, and the sensation is harsh with the Float DPX2 shock.

The Levo SL’s handling is nice and lively, though the front-end steering is a little light with the 51mm fork offset, resulting in some twitchiness at speed. In comparison the Fuel EXe feels better balanced across a range of riding speeds thanks to its solid chassis and well-damped suspension. It’s no doubt the more modern bike of the two, making the two year-old Levo SL feel a little outdated.

It also has to be said that the Fuel EXe kills it on value compared to the Levo SL. The Levo SL Expert we tested features a Fox 36 GRIP2 fork and Float DPX2 shock, alloy Roval wheels, a SRAM GX/X01 drivetrain and Code RS brakes. In comparison, the Fuel EXe 9.8 XT gets a similar level of suspension albeit with a Shimano XT groupset, carbon wheels, carbon cranks and a one-piece carbon cockpit. Despite featuring a higher-end spec, the Fuel EXe sells for $2,100 AUD less , making for a far more appealing package.

The Orbea Rise arrived not long after the Levo SL at the tail-end of 2020, though it took a slightly different tact by taking an off-the-shelf Shimano EP8 motor and de-tuning it to reduce the peak torque output to 60Nm. Orbea also developed its own ‘RS’ firmware for the Japanese motor, which aimed to provide a more natural feel to the power delivery while improving efficiency. This was then paired to a smaller 360Wh battery and a gorgeously svelte carbon frame to deliver complete bike weights from as low as 16.2kg.

The more sensibly-spec’d Rise M10 we tested came in at 18.38kg, though it was fitted with lightweight Maxxis tyres that felt somewhat out of place. With more appropriate rubber, the Rise would likely come in at a similar weight to the Fuel EXe.

While value for money from Orbea is better than Specialized, it’s still not as impressive as the Fuel EXe. The Rise M10 comes with blingy Factory Series Fox suspension, a Shimano SLX/XT drivetrain and alloy Race Face wheels, but sells for two grand more than the Fuel EXe 9.8 XT.

On the trail the Rise is a closer match to the Fuel EXe. The geometry is pretty similar, though the Rise chassis doesn’t feel quite as stout when being pushed hard. This also comes down to the steeper head angle (65.5° vs 64.7°), and it’s also due to the suspension, which is marginally more sensitive off-the-top. It delivers terrific traction and a comfortable ride quality, though it’s not as supportive as the Fuel EXe.

Speaking of suspension, we wouldn’t be opposed to seeing both the Rise and Fuel EXe equipped with 150mm of rear travel like the Levo SL. Sure these are lightweight e-MTBs, but travel is travel, and we’re still talking about 18+kg bikes that are capable of going very fast on rough terrain. That said, any increase might see them encroaching too far into the territory of their bigger travel, full-powered siblings (the Wild FS and Rail).

We found there to be terrific power on tap from the Rise’ EP8-RS motor, and the E-Tube app allows you to tweak the acceleration response and assistance character of each setting, depending on how you want the power to come on. The stock tune works mighty well though, with the Rise being an efficient performer that feels natural and intuitive on the trail, with just a fraction more punch available for scaling crux features on a technical climb.

As mentioned earlier, the Shimano EP8 drive unit is much noisier than the Fuel EXe’s TQ motor, which is basically silent in comparison – both on the climbs and on the descents. We also prefer the clean integration of the TQ system, with its bright and easy-to-read top tube display. The standard display on the Rise is a rather austere junction box that features a couple of tiny LEDs. You can upgrade this to the Shimano EM800 display for an additional fee, though it comes with additional wires that add clutter to the cockpit. It’s plenty functional, just not as tidy as the Fuel EXe.

Flow’s Verdict

The Trek Fuel EXe is a terrific example of just how far e-MTB technology has come. Not only is it a fantastic looking bike that’s low on bulk, it also manages to deliver a load of performance out of an impressively lightweight package.

The unique TQ motor is stunningly quiet, and for many riders its 50Nm output will be ideal. Heavier folks and those chasing maximum power with maximum range will still be better served by the Rail and is full-powered Bosch motor. The Rail also features a plusher ride quality that suits brainless bombing down the roughest descents.

In comparison the Fuel EXe is a more involving bike to ride, and it rewards an active pilot that seeks to work and play with the terrain. It’s responsive and fun to ride on twisty singletrack, with the sort of on-point handling and geometry that we expect we’ll be seeing in the next generation Fuel EX.

While the suspension isn’t buttery smooth over smaller chatter, it does produce a heap of support and incredible control at higher speeds. Along with the stout chassis, the Fuel EXe exhibits a well-damped ride quality that shrugs off the big hits and awkward landings despite not having a tonne of travel.

Indeed for those riders who are looking for that hallowed middle-ground between a regular mountain bike and an e-MTB, the Fuel EXe presents one of the most compelling options to date.
