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.

Trek Fuel EX 5 Review

2023 Trek Fuel EX 9.8 GX-Satin Black Olive

It would be unconvincing if I just told you how perfect the Trek Fuel EX 9.8 GX’s superior performance is, so in this review, the Trek Fuel EX 9.8 GX joined us on a professional trail. From the slick ascents of rough, year-round training to the dangerous downhills of sharp rubble and fallen branches, the Trek Fuel EX 9.8 GX Gen 5 is officially tested.

In the beginning, based on the emphasis on the woodland, I adjusted the shape of the car to a high-geometry climbing shape, and I was completely ready for a big fight.

During the rapid acceleration, I tightened my muscles and started to go all out, and the process was not as easy as I thought. The 1×12 drivetrain gave me the most bang for my buck, while the grippy, grippy tires kept me from skidding during fast rides.

The tires are full of aramid beads. Although it is an unremarkable design, it is also a great help in increasing friction. The all-carbon brazed body includes rims and front fork components to maximize shock absorption.

The Trek Fuel EX 9.8 GX weighs in at 13.1kg, which is about as heavy as a sleeping bulldog in my living room. I can lift it easily.

This is a section of trail terrain that is not so straight, and collisions with the body during sharp turns are a concern for most drivers. Although the performance of carbon brazing is balanced, it also means that it is more brittle and prone to damage.

I have to admit that the Trek Fuel EX 9.8 GX has achieved the ultimate in design details. There are also models without bumpers in the same price range. In my opinion, this is essential for riding.

Trek Fuel EX 9.8 GX - Lithium Grey/Factory Orange

When I reached the highest altitude, our conquest of climbing had come to an end, and the next step was the more exciting rapid descent and dive test. When I looked at the broken and sharp rubble on the forest road, my heart was nervous.

I’ve been involved in riding for years, but in the face of this uncertain and dangerous terrain, I’m still full of energy and prepared for the worst. In the control of the body during big bumps, whether the car itself can withstand the constant ups and downs of stimulation…

These are all things I have to consider. I double-checked the springs, dampers, brakes, and when I was ready, I took a deep breath and started sprinting.

During the rapid descent, it was indeed very thrilling. The countless gravel bumped my body and shook my arm muscles, but it was much lighter than I thought.

I think this is because the carbon fiber material of the body absorbs vibration and the cooperation of the front and rear triangles, through the compression and extension swing of the shock absorber, to reduce the vibration effect. Even in bumpy and rough road conditions, the tires remain firmly on the ground to maintain optimum pedaling efficiency and ground contact performance.

I still have good control over the Trek Fuel EX 9.8 GX.

Main Feature

When you get your hands on this car, you’ll be amazed at the unique quality of the Trek Fuel EX 9.8 GX itself. Glossy carbon braided body, I’m really obsessed with this material.

But it has to be said that for beginners, this material may have higher professional requirements for you. It is so light and so strong, the two seem to be contradictory, but they can be well integrated.

The cooperation of the front and rear triangles can maximize its absorption and shock absorption effect. There are also many choices in color design (Lithium Grey / Factory Orange; Matte Carbon Smoke; Satin Black Olive; Raw Carbon / Rage Red).

The variety of colors is really rare for Trek. Anyone who knows me will know that I have always complained about the single-color Trek.

It is still a noble internal wiring design, and I appreciate the internal wiring very much. It can best protect the performance of the important lines of the body, and in very harsh environments, it is still not damaged by mud.

You must know that we often encounter rainy days, and we have no choice but to sprint the entire track in the face of roads full of mud. Internal wiring does save a lot of trouble for our follow-up maintenance. I’d rather drink a full case of beer with the drivers at the end of a race than spend a lot of time tending my car.

In terms of details, I appreciate Trek Fuel EX, whether it is the storage function of the body and the design of the increased shock block. It is very necessary to carry the necessary food to supplement physical strength when riding at high speed.

The classic 75.0-degree seat tube angle makes you more comfortable in your sitting position. Because of years of riding, I have tried many models. If you feel uncomfortable in the position, it will cause a lot of damage to the muscles, and you will feel uncomfortable after a riding competition.

With a 66.0-degree head tube angle, there is nothing to fault in terms of riding experience. Of course, if your upper body is too long, then you have to check the size chart and choose carefully to avoid exchange. (for reference I’m 5’8″, choose size M)

The Fox Performance 36 front and rear travel combination (140mm (front) and 130mm (rear)) made it easy for me to climb and descend, which greatly reduced the impact force on the body. You can master more in body control, and adjust your state at any time according to the terrain.

In terms of braking power, as I mentioned earlier, the SRAM GX Eagle’s 1×12 dynamic braking system can provide me with great assistance during the ride. My riding experience with the Trek Fuel EX 9.8 GX can give a standard A rating.

Components and Specifications

Sram gx eagle 1×12 drivetrain.

Trek Fuel EX 9.8 GX has SRAM GX Eagle 1x12 Drivetrain

As I have always emphasized, I am obsessed with trail riding, not only because of the unknown risks, but also because of the thrill of approaching the limit in speed challenges.

Whether it’s breaking resistance uphill, it can also give you a lot of confidence on rougher roads, thanks to the SRAM GX Eagle 1×12 drivetrain.

I still remember my race in Southern California, and even though the riders I was with were very capable, the SRAM GX Eagle 1×12’s range of 22-speed options gave me a lot of confidence.

Float EVOL Air Spring

For the Trek Fuel EX 9.8 GX, weight has always been its strength. In the design of reducing the weight of the body, the load EVOL air spring has achieved a high level in its ability to absorb vibration and reduce the body being squeezed.

I think the designers at Trek must have put a lot of thought into it. At this point, I feel compelled to point it out to my readers.

SRAM G2 RS 4 Brake Hydraulic Disc

The SRAM G2 RS 4 brake hydraulic disc itself is a statement of technology, a new trend over traditional mechanical discs. If you know bicycle accessories, you should know that we have gone through a big leap from mechanical discs to hydraulic discs.

This kind of leap can be explained from two aspects. First, the hydraulic disc is more sensitive to emergencies, and second, the load also greatly reduces the burden on the body, so that you can make a big leap in high-speed driving. best level.

But there is one regret that I still need to share for the sake of honesty. The maintenance cost of the hydraulic disc is higher than that of the mechanical disc, and the maintenance is more careful than the mechanical disc, so it is also expensive.

Other Versions of Trek Fuel EX

Trek fuel ex 9.9 x01 axs.

Compared to the Trek Fuel EX 9.9 X01 AXS, we were surprised to find the Trek Fuel EX 9.8 GX’s price/performance ratio was outstanding. Although the Trek Fuel EX 9.9 X01 AXS and 9.8 GX share the same full carbon fiber material, they also have the same liquid discs on the brakes and even the fork selection.

But the Trek Fuel EX 9.8 GX is about $4,000 more expensive. Although it is lighter in body weight (Trek Fuel EX 9.8 GX weighs 12,8kg), that doesn’t quite convince me.

In terms of suspension travel, the Trek Fuel EX 9.9 X01 AXS has not been upgraded, and it is still the front (140mm) and rear (130mm) travel design, which means it is faster and more stable when climbing and descending.

So in general, on the more important performance components, the Trek Fuel EX 9.9 X01 AXS has not achieved a complete leap.

Trek Fuel EX 8

When compared with the Trek Fuel EX 8, it was found that the Trek Fuel EX 9.8 GX achieved a relatively large improvement, although the price also increased accordingly. However, by comparing the data, we found that the following important components have been upgraded.

First up is the fork, from the Trek Fuel EX 8’s Fox Rhythm Float 34 to the Fox Performance Float 36, which means a breakthrough in both shock and weight. Second, the Fuel EX 9.8 GX is lighter, which makes it easier on some uphills and jumps.

Compared to the Trek Fuel EX 9.8 GX’s higher version of the SRAM G2 RS hydraulic disc, the Trek Fuel EX 8 features a Shimano 4 hydraulic disc, which is far less sensitive and lighter than the Trek Fuel EX 9.8 GX. So if you’re looking for a more durable and performant full-suspension bike, I’d go for the Trek Fuel EX 9.8 GX.

In terms of riding and performance, each upgrade means a completely different riding experience and stable handling performance, and it can also save a lot of trouble in subsequent upgrades.

Comparison Table

Ibis ripley gx vs trek fuel ex 9.8 gx.

In terms of body weight, the Ibis Ripley GX reaches 2.3 kg, which is a big drag for the body to climb. Secondly, we all know that we will encounter some big jumps because of the high speed when riding on the trail, so it is necessary to ride a lighter bike.

In terms of fork performance, the Trek Fuel EX 9.8 GX Fox Performance Float 36 fork is more professional, and is superior to the Ibis Ripley GX’s Fox Factory Float 34 in terms of shock absorption and stiffness.

So, if you’re looking for superior performance and don’t want the necessary expense of some fork upgrades, I think the Trek Fuel EX 9.8 GX is a better choice.

BMC Fourstroke 01 vs Trek Fuel EX 9.8 GX

When it comes to choosing a professional trail, I believe the BMC Fourstroke 01 is definitely in your choice. First of all, in a strict sense, the frame weight of the BMC Fourstroke 01, LT | TWO is greater than that of the Trek Fuel EX 9.8 GX.

Thanks to Trek’s traditional hand-crafted carbon fiber bodywork process, Trek has achieved the maximum weight in terms of body weight. Secondly, in terms of price, Trek Fuel EX 9.8 GX is more economical and has made concessions in price.

The Trek Fuel EX 9.8 GX has also been upgraded with a more professional Fox Performance Float 36 fork in my preferred fork choice. Anyone who knows me will know that I like the Trek Fuel EX 9.8 GX’s Bontrager tires very well.

Compared to the DT SWISS tires used on the BMC Fourstroke 01, the Bontrager rims are thicker and the wheels are thicker. Smoother, stronger, and less likely to blow out, so we felt the Trek Fuel EX 9.8 GX was smoother when we rode it.

Revel Rascal – GX Eagle vs Trek Fuel EX 9.8 GX

As a consumer, when you see the price of the Revel Rascal – GX Eagle, you will definitely be a little excited because it is more affordable. Comparing the details of the two, in the material of the rim, in order to reduce the cost, the Revel Rascal – GX Eagle uses the Industry Nine Enduro S 1/1 29″ alloy Wheelset, although it is marked (*upgrade available).

Compared to the carbon fiber material of the Trek Fuel EX 9.8 GX, the carbon fiber material absorbs more force when it is subjected to larger impacts, which means that the rider is more able to control the fast bike. Design-wise, if you’ve got the actual two bikes and felt them, you should be able to understand why I prefer the design of the Trek Fuel EX 9.8 GX because of the placement and angle of the shocks.

I think Trek Fuel EX 9.8 GX The EX 9.8 GX can more efficiently cooperate with the body to expand and contract, so as to maximize the absorption of vibrations and reduce the bumps of the body. On the professional track, it is more friendly to ride on the ground and roll quickly.

Giant Trance X Advanced E+ 2 vs Trek Fuel EX 9.8 GX

The Giant Trance X Advanced E+ 2 is all about high performance, and certainly at a high price. Comparing the various data of Trek Fuel EX 9.8 GX, Giant has made some upgrades.

It can be seen that the travel of the suspension is 140mm in the front and 140mm in the rear. The Giant Trance X Advanced E+ 2 has some electric upgrades, such as a Yamaha 250W 85Nm mid-drive motor.

However, for some traditional riders, this is an optional feature. Of course, this kind of innovation and upgrading is also a major trend. Like I said, if you want a traditional ride and you’re not that comfortable with hybrids, I think you can wait until electric hybrids are more mature and try out this expensive model.

In case, the above comments are helpful to you, please remember to share the subscription. Have a great day!

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.

2023 trek fuel exe 9.9 xx1 axs bontrager se5

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.

What's new on the 2023 Trek Fuel EX?

Check out the Trek Fuel EX overview below and learn about all its exciting updates.

More front and rear travel

Year after year, riders continue to push the limits of trail bikes and the Fuel EX Gen 6 delivers longer travel suspension for dominating steeper terrain.

Front travel increases from 130mm to 140mm and the rear shock provides 150mm of cushion, up from 140mm on the previous model.

Adjustable Geometry

The 2023 Fuel EX also introduces an innovative adjustable headset that can alter the head tube angle by +/- 1 degree depending on the desired slackness.

The head tube angle can be set between 63.5 and 65.5 degrees.

The angle adjust cups combine with the Mino Link for a total of 6 possible geometry configurations.

Size specific builds

Trek has matched the frame sizes with appropriate wheel choices and chainstay lengths to ensure all riders achieve an ideal fit.

XS models run nimble 27.5” wheels whereas frame sizes medium and up have 29ers. Small frames are available in both wheel options.

All riders, regardless of their height, can find a bike that provides maximum control and handling.

New frame features

The reimagined frame boasts trendy tech, including a full length downtube guard for protection from debris and tailgates during shuttle runs.

The new threaded BB and guided internal routing keep everything neatly tucked away and low-maintenance.

The larger 34.6mm seat tube accommodates sturdier dropper posts and now all frames— carbon and alloy— come with handy downtube storage .

Adjustable suspension progression

Riders can effortlessly switch between suspension settings via a flip chip on the lower shock mount.

Choose between the plush, less progressive setting for better trail feedback or the more progressive setting that’s better for aggressive riding.

The progressive option avoids bottoming-out and performs great with linear coil shocks if you choose to upgrade later on.

Trek Fuel EX Geometry

The new Fuel EX features a steeper seat angle and longer reach for more efficient climbing and improved handling on demanding descents.

This more aggressive geometry can be further fine-tuned from inside the headset with angle adjust cups (sold separately) as well as the rear triangle Mino Link, r esulting in 6 different geo configurations .

Trek Fuel EX Size Chart

Trek outfitted each frame option with the correct wheel size to optimize handling. XS models come with 27.5” wheels, frames M and up run 29ers. People who ride S frames are often caught in the middle, so those frames are available with both wheel options.

*Size XXL available in alloy only.

Trek Fuel EX Vs Top Fuel Mountain Bike ?

Trek mountain bikes are built for the trails, and no bikes illustrate that better than the Trek Fuel EX and Trek Top Fuel. So, it’s understandable to pit Trek Fuel EX vs Top Fuel, which compels us to ask, what’s the difference?

Trek Fuel EX is a full suspension 29er trail bike with a 140mm front suspension and a 130mm rear suspension, while Trek Top Fuel is a 29er or 27.5-inch full-suspension cross-country bike with a 120mm front and rear suspension.

So, you can distinguish the trail bikes according to the type, suspension travel, and wheel size. Other differences are with respect to the geometry, suspension technology, project one customization, speed, weight, and even price.

what is the difference between trek top fuel and fuel ex

Below is a table breakdown of all the nine differences between Fuel EX and Top Fuel to be explored in detail later:

This article will not just discuss the differences between the two Trek MTBs but will also highlight their similarities. Without saying much, let’s begin with the bikes’ overview.

Trek Fuel EX Overview

Trek Fuel EX is a full suspension trail mountain bike by Trek designed to take on just about any trail all season long.

This mountain bike comes with a balanced trail geometry that brings out the perfect balance between speed and control. As a result, it’s easier to handle on tricky trails and promises a fast pace.

Fuel EX is available in 29-inch (29er) and 27.5-inch wheel sizes to accommodate all heights. Women who naturally have a shorter stature can set for 27.5-inch options, while men who are inherently taller can go for 29ers.

Suspension-wise, Fuel EX features a 140mm front suspension and a 130mm rear suspension, which is enough to hit just about any trail and enjoy the same comfort and bump-cushioning.

In terms of suspension technologies, the manufacturer employs Mono Link to self-adjust the bike frame, Re: Aktiv to offer you more control, and Active Braking Pivot for more confident braking.

The most notable miss is the Project One customization option. But we’ve several models to choose from, such as Fuel EX 5 Deore, Fuel EX 9.1XOR, Fuel EX7, Fuel EX 8, Fuel EX9.7, Fuel EX 9.8 GX/XT/GX AXS, Fuel EX9.9 XTR, and Fuel EX 9.9X01 AXS.

Overall, Trek Fuel EX is perfect for anyone who wants a versatile do-it-all mountain bike.

Trek Top Fuel Overview

Trek Top Fuel is a short travel 29er cross country mountain bike designed for cross country racing and fun trail riding.

This bike is more forgiving and impulsive on aggressive descents than regular XC bikes but has a snappier feel than a traditional trail bike. So, it gives you the best sense of both worlds.

It has a 120mm front suspension and 120mm rear suspension to have a more comfortable and confident ride. And since it’s a 29er, obstacle rolling is much funnier. The full-suspension XC bike enjoys a progressive geometry, which is more relaxed and offers you more control.

Suspension-wise, this XC bike employs Mono Link Technology and ABP, just like Fuel EX to promise self-adjustment geometry and confident braking.

But unlike Fuel EX, Top Fuel lacks Re: Aktiv suspension technology. Instead, it employs Anti-Squad technology, a suspension resistance technology that offers you more acceleration with every pedaling. That’s practically why this bike is a better cross-country racing bike.

The best bit is that Top Fuel is customizable through Project One. But still, the bike family is split into several models – which include Top Fuel 5 Deore, Top Fuel 7 Deore/XT, Top Fuel 9.7 SLX/XT, Top Fuel 8, Top Fuel 9.8 GX/AX SXS/XT, and Top Fuel 9.9X01/XTR/XX1 AXS.

Trek Fuel EX Vs Top Fuel Side-By-Side Comparison!

Now, here is how Fuel EX and Top Fuel compare:

1. Bike Type

Fuel EX is generally a trail mountain bike that can take on just about any trail every day – from dirt trails to rough off-roads and forest trails.

On the other hand, Top Fuel is a cross-country mountain bike that you can use for any cross-country event. Whether you want to compete at a local event or race casually in the countryside, you cannot go wrong with Top Fuel.

2. Suspension Travel

Fuel EX is a do-it-all mountain bike mainly because of its long travel range. The bike features 140mmm of front suspension and 130mm of rear suspension, enough to take on all terrains.

The suspension allows you to ride downslope and go over rocks. That’s how powerful the MTB is. Top Fuel promises 120mm suspension travel on the front and rear side, shorter than what you get from Fuel EX but enough for cross-country biking.

You want your cross-country race bike to feel lightweight and offer you better control, and that’s what you get from the 120mm travel range.

3. Trek Fuel EX Vs Trek Top Fuel Wheel Size

Top Fuel is a 29-er (29-inch mountain bike), while Fuel EX offers 29-inch and 27.5-inch wheel options. The difference is that 29ers mostly favor taller guys while 27.5-inch accommodate both taller and shorter guys.

So, you are more likely to get a matching fit with Fuel EX than Top Fuel. However, the advantage of Top Fuel is that you can have a custom-made bike matching your body size.

4. Geometry

These two Trek mountain bike families differ in their geometry, which affects their overall feel.

Fuel EX, for example, has a balanced trail geometry, which bridges the gap between the fast-handling short-trail geometry and the slow-handling greater-trail geometry.

As a result, the bike is easier to handle at high-speed and, pretty stable, and offers you more control. You cannot ask for anything better than a balanced trail geometry.

On the other hand, Top Fuel has a progressive geometry characterized by a longer wheelbase, thus more relaxed and promising more control.

5. Trek Top Fuel Vs Fuel EX Suspension Technology

Both Trek MTBs employ Active Braking Pivot (ABP) and Mono Link suspension technologies. ABP generally tunes the bike suspension to the braking and acceleration to enable you to brake more confidently and boss the trail.

Mono Link in opposite allows you to adjust the bike’s geometry quickly and on the go. The difference is that Fuel EX employs Re: Aktiv suspension technology while Top Fuel uses Anti-Squat suspension technology.

Re: Aktiv offers Fuel EX more grip, control, and a responsive feel, while Anti-Squat suspension allows you to go faster with every step. The more you pedal a Top Fuel, the faster it accelerates.

6. Trek Ex Vs Top Fuel Project One

Project One is Trek bike’s customization project. While Project One is available for top high-end Top Fuel models, it’s not available for Fuel EX. So, if you want a custom-made MTB for competition, Top Fuel is the way to go.

That, however, doesn’t make Fuel EX an inferior family. No! There are so many high-end Fuel EX models to choose from, and they all come in all frame sizes, which means you can easily find your fit.

7. Bike Weight

There is at least a 2-4-pound difference between Fuel EX and Top Fuel of the same generation and size. For example, while Fuel EX 9.9 X01 AXS weighs 28.15 pounds, Top Fuel 9.9 XXL weighs 26.13 pounds.

That makes Top Fuel lighter than Fuel EX, and it’s understandable, given that Top Fuel is a cross-country racer while Fuel EX is a trail bike.

8. Top Speed

Being the lighter of the two and employing Anti-Squat technology makes Top Fuel faster than Fuel EX. That hugely explains why Top Fuel is a cross-country bike as it’s speedy, thus suitable got cross county.

Though you can race with a Fuel EX since it’s an all-terrain trail bike, you cannot go as fast as someone riding an XC bike, which is Top Fuel.

9. Bike Price

Trek Top Fuel costs more than Fuel EX because of the lower weight advantage, anti-squat technology, and Project One customization availability.

Trek Fuel EX Vs Top Fuel Similarities

After looking at the things that set Fuel EX and Top Fuel apart, here are some things that the two Trek MTBs have in common.

Suspension Technologies – Both bikes employ Active Braking Pivot (ABP) and Mono Link suspension. ABP promotes confident braking while Mino Link encourages geometry adjustment on the go.

Frame – Both families employ alpha aluminum on their mid-range bikes and OCLV carbon on high-end options.

Sizes – Both bike families come in all frame sizes as follows:

Extra small (rider’s height: 137-155cm)
Small (rider’s height: 153-166.5cm)
Medium (rider’s height: 161-172cm)
Medium/Large (rider’s height – 165.5- 179cm)
Large (rider’s height: 177-188cm)
Extra Large (rider’s Height – 186-196cm

Weight Limit – These two bike families limit their load capacities to 300 pounds. So, they are equally strong and perfect for heavyweight guys.

2. Is The Trek Fuel EX A Trial Bike?

Yes, Trek Fuel EX is a trail bike. It is a full-suspension trail bike with 140mm front suspension and 130mm rear suspension.

3. How Much Travel Does the Trek Fuel EX Have?

Trek Fuel EX comes with a 140mm front suspension and 130mmm rear suspension. The suspension offers optimum bump absorption and stability to take on just about any trail.

Closing Thought on Trek Fuel EX Vs Top Fuel:

Generally, Trek Fuel EX is an all-terrain trail bike with a 140mm front suspension and 130mm rear suspension. On the other hand, Trek Top Fuel is a cross country racing 29er with a 120mm front and rear suspension.
