2019 Trek Powerfly FS 5 Review – Turbo or Nothing!

E-Bikes are tonnes of fun. So an E-Bike from Trek must be tonnes more fun, right?! Trek’s 2019 Powerfly absolutely flattens climbs, and tumbles downhill with zero hesitation. With 250 watts of pedal power at your disposal, riding uphill is as dangerous as going downhill!

The Trek Powerfly FS 5 is second highest model in the range, in terms of spec. Right behind the FS 7, which comes out with some better suspension upfront, and an 11spd drivetrain. There is also good news, for the lady mountain bikers out there; Trek offer a FS 5 women specific model. All with the same components as the men’s FS 5, apart from the women specific saddle.   

Trek’s Powerfly FS 5 full-suspension, frame bridges the gap between smart integration, and sturdy performance. It offers Motor Armour, and a Knock Block head tube. The Alpha Platinum Aluminium, which Trek swear by, has been manipulated around the motor of the bike. While offering 130mm of rear shock travel. The battery also slots in conveniently from the right-side of the downtube, and can be easily removed for charging. The brand has accomplished this, without compromising on good mountain bike characteristics.

The E-bike Aspect:

The Bosch CX Performance motor spits out 250 watts of assistance. It comes with Bosch’s gear-shift detection technology. Which holds back strain on the chain of the gear-set while it hops from one gear to another. The motor itself is governed to cut out at 25km/h, yet still amplifies your pedalling force by 300% in turbo mode. What’s also cool and different about the CX Performance motor, is that it has an intelligent E-MTB motor mode. Which automatically decides how much assistance you need based on the terrain.

As far as battery life is concerned, the Powerfly FS 5 has a surplus of it. The 500wh battery, will give you a max range of 120km – in eco-mode. Usually, the battery is the bulkiest part of an e-bike. However, with Trek’s nifty side insertion on the downtube, you hardly notice it. You can also charge the battery without removing it from the bike. There’s a charging port near the motor, where you can plug the battery in to an electrical circuit.

Sneaky Suspension:

For a heavy E-Mountain Bike, the Powerfly’s suspension coped with the extra force brilliantly. Truth be told, the RockShox Recon RL fork was E-bike specific, and engineered more stiff than conventional forks. Its 130mm of travel, correspondingly had a distinguishable, smooth, compression. While the rear RockShox Deluxe RL shock, doesn’t include Trek’s RE:aktiv technology, it does come paired with a carbon rocker and Mino-Link. Does that make up for the missing RE:aktiv technology? We wouldn’t say so entirely, as the shock did feel a little sticky sometimes.

Geometry:  

The geometry that Trek have managed to pull-off with the Powerfly, impressed us greatly. The E-bike had a 67.4-degree head-tube angle, with a BB height of 33.3 cm. So the bike could clear the terrain below, with ease. A chain-stay length of 47.4 cm allowed the bike to handle like a traditional trail bike, by giving responsive traction on the back wheel.

There’s“power” in the Powerfly’s name. Needless to say, on climbs the bike waspowerful, and lethal. The pedal assist pretty much sprinted the bike uphill,with hardly much effort on our side. However, the only that held us back alittle, was the 10 speed gear-set. Yes, 10 gears are enough when riding an E-bike. But for the terrain we were on, mainly steep and technical, the drivetrain seemed a bit limiting.

Whilst flying during your climbing interval is certainly not far-fetched on the Powerfly, it is equally as fast on the downhills. The motor helps carry good momentum, but relents its power when the speedometer hits 25km/h. We can understand why. Since you don’t really need much assistance going downhill.   The suspension also proved to be superbly forgiving, despite the added weight of the bike’s battery and motor. One thing that we might change, however, is the tyre size. A wider tyre will add loads more control on descends.

The same can be said about how the bike corners through single-track. Wider tyres will add more control and stability, as the E-bike did tend to over-shoot corners a little. We know E-bikes can’t all be perfect. But the Trek Powerfly FS5 needs more potent brakes. Perhaps a higher model brake-set in the Shimano hydraulic disc range will do. Apart from adding stronger brakes and fatter tyres, the Powerfly is loaded with rad-ness. And the ride quality of the bike along the narrow trail, is quite golden.

The Trek team have integrated the motor and battery into the Powerfly’s frame, in a smart manner. As a result, a full-on focused E-bike bike was born. There is an atmosphere that implies that Trek have skimped on higher spec’d, mountain bike, components. But let’s face it, you’re not going to buy the Powerfly FS 5 to be the next Nino Schurter. You’re going to buy the E-bike, to have an awesome time on the trail, and on that level, the Powerfly more than delivers!

Trek Powerfly 5 Review

When you purchase through links on our website, we may earn a commission. Affiliate disclosure.

When it comes to hardtail electric mountain bikes there’s an awful lot of choice (if they’re in stock) from the big-name manufacturers. When one of my friends called me last week to say he’d brought a Trek, I was eager to try it out. In this Trek Powerfly 5 review, I will take a closer look at the specifications and share with you my opinions after spending a couple of hours with it on Bodmin Moor .

Introduction

Trek’s mountain bike heritage goes back to 1983 when they released the 850 – fast forward 28 years and they have a comprehensive range of high-end e-MTBs ranging in price from just over £2500 to up to an eye-watering £11500.

At £3750 the Trek Powerfly 5 sits at the upper end of their hardtail range and benefits from the latest Bosch Performance Line CX motor with a 625Wh battery. The Powerfly 5 also boasts Rockshox forks and SRAM Eagle SX 12-speed drivetrain.

My friend had been talking about upgrading his Cube Acid hardtail e-MTB for some time and we’d previously discussed the merits of the Trek. He recently took the plunge and purchased the bike reviewed here.

First impressions

The first thing that struck me about the Trek Powerfly 5 was how stunning the paintwork finish is – it’s a gorgeous bike in the ‘slate/volt’ colour scheme. Mind you, you’d expect nothing short of this on an e-bike costing more than a decent second-hand car!

Although the 17″ frame was a bit on the short side for me, with the seat post properly adjusted it felt quite comfortable. My friend paid an extra £200 to have the optional Bontrager dropper seat post fitted, which is a must if you’re going to be tackling the trails.

Riding some rock-strewn single track the Trek feels sure-footed. For an older rider like me, the Powerfly 5 inspires confidence (maybe a bit too much) and is great fun to ride. Where this e-bike comes into its own is when the trail turns upwards – it’s not the first Bosch CX I’ve experienced but this motor never fails to impress me with its 85Nm of torque. Riding up steep tracks is helped even further by the trail-busting SRAM Eagle 11-50 12-speed rear cassette, meaning you never run out of gears.

Although my ride was fairly brief I was thoroughly impressed with the off-road abilities of the Trek, it’s a great all-around package suitable for beginners, intermediate or the older more experienced cyclist who’s returning to mountain biking after a long break. Below I will go into more detail on the components.

Check out the 2023 Powerfly 5 from Trek

Electric components

The high-end mountain bike world is dominated by either the Bosch CX or Shimano Steps E8000 / EP8 of Brose motors. It’s good that manufacturers recognised the demand for a greater battery range and the Trek Powerfly 5 comes with the Bosch 625Wh power tube battery which is neatly integrated into the frame.

Bosch Performance Line CX

The Bosch Performance Line CX motor benefits from several upgrades over the previous model, most notably the 85Nm torque output offering the rider up to 340% assistance.

There’s the new Extended Boost mode which makes negotiating rocks and exposed roots on the trail much easier, particularly uphill. This means the bike can be manoeuvred with greater agility on technical sections.

Revised e-MTB mode – This ensures the rider is well-prepared for whatever situation the trail has in store. New sensor and motor control functions give mountain bikers a much wider range of dynamic and natural support.

The Bosch motor is smooth and the whine from the motor is quiet and not intrusive. Performance is as good as you will find on a road-legal e-MTB and it adds a whole new dimension of fun when riding off-road.

625Wh Powertube battery

I first rode an e-bike with a 625Wh battery at the end of 2019 and having the extra capacity will ensure riders can spend more time enjoying the trails. The range will depend on lots of different variables but 50 miles should be achievable when riding off-road – check out the Bosch range calculator for a rough estimate of battery range from the 625Wh battery.

Bike components

Quality components are a must on electric mountain bikes at this price point and the Trek Powerfly 5 doesn’t disappoint. I have gone into more detail on the specification below.

The gearing is comprised of an SRAM Eagle single-click 12-speed shifter with an NX Eagle rear derailleur and 11-50 cassette – as the Bosch uses an ISIS-type crank interface, an SRAM X1 crankset is fitted. The drivetrain is finished off with a high-quality SRAM SX Eagle chain.

Braking is provided by the excellent Shimano MT-420 4-pot calipers with 203mm brake rotors – as expected these brakes work well and will provide more than enough stopping power for most riders. I found them to be excellent, and you only need to use one finger for braking.

If found the 120mm Rockshox Recon RL suspension forks worked very well indeed. Although they are at the lower end of Rockshox forks they feature trickle-down technology from more expensive forks and feature Motion Control™ damping which features low-speed compression adjustment to lockout.

Wheels and tyres

The wheelset is a disc-specific Bontrager Kovee Comp 23 with Boost 110, 15 mm thru axle at the front and a Boost 148, 12 mm thru axle at the rear. Tyres are Bontrager XR3 Comp, wire bead, 30 tpi, 29×2.30″ which seemed to handle the damp moorland trails very well. If you wish to upgrade to a tubeless set-up these wheels are tubeless-ready. The hub is a standard 9/10 speed Shimano freehub.

Frame and finishing kit

For the frame Trek use their Alpha Platinum Aluminium which is their premium lightweight aluminium designed for maximum strength and minimum weight. As I’ve mentioned above the finish is exquisite and looks incredibly hard to wear.  The frame also benefits from internal routing for lights (should you choose to fit them) and a direct kickstand mount.

All of the finishing kits are all by Trek’s in-house brand Bontrager which is of excellent quality. This bike also had the optional Bontrager Line Dropper seat post fitted which costs an additional £199.99.

If I was in the market for a capable hardtail electric mountain bike I’d be very tempted by the Trek Powerfly 5. It’s great fun to ride and feels very capable on a rough single track – the handling inspires confidence and that Bosch motor is the icing on the cake!

There are cheaper options available and if you’re new to electric mountain biking you may not want to spend quite so much on your first purchase.

Having said that, if I had the money to spend on a nice hardtail e-MTB the Trek would certainly be on my shortlist. Other plus points are the excellent brakes, SRAM 1 x 12 gearing and the 625Wh battery.

My friend has brought this e-bike with the intention of keeping it for a good few years and I’ll post any relevant updates here.

Thanks for reading and if you have any questions or comments please leave them below.

Thanks for the review, even though I discovered this after buying my Powerfly 5, I still found it useful and relatable. I picked mine up in November and have given it a good testing over the winter months – what a brilliant bike! Even though I could have spent less for a Cube reaction, which I almost did. I’m glad I spent more on this. The only issues I have encountered are tyre pressures since going tubeless, but I think that’s more the tape inside rather than the rims thenself.

Table of contents, trek powerfly 5 gen 3 review (2023).

The Trek Powerfly range comes in many guises.

The large series of Powerfly bikes include hardtail commuters, which can go bike touring and also take on the dirt, along with the Powerfly Full Suspension rides, which are geared up for more aggressive riding.

The standard Trek Powerfly hardtails stand somewhere in between, and that includes the Trek Powerfly 5, which we’re featuring in this review. Lighter and made to move speedily across multiple terrain types – from urban settings, as well as gravel trails and forest roads.

So, can the Powerfly 5 Gen 3 straddle these multiple worlds successfully? Or does it falter at the first hurdle?

Our Verdict

One of the best mixed terrain and commuter hardtails we’ve had the pleasure of riding.

Trek has created a wonderful versatile e-MTB, with long range, brilliant motor and at a very reasonable price. The bike ticks a heck of a lot of boxes and for a versatile commuter – it absolutely smashes it.

The display is the only real let down, but that’s an easy fix if you swap it out for another. Overall, it’s a real success and dare we say it – a bargain in the notoriously expensive e-MTB market.

• Ride experience
• Could offer slightly more travel in small size frames

Trek Powerfly 5 Gen 3

Price: $4,546

Weight/frame.

The Trek Powerfly 5 has a strong aluminium frame, made out of the company’s Alpha Platinum aluminium compound. It’s a sturdy old bike, capable of soaking up lots of pressure – however, it means a little extra weight, with the bike coming in at 22.94kg in a size medium frame .

You get more than 2kg of weight saving though compared to the Powerfly 5 Equipped, which has a luggage cage over the back wheel and a longer frame. That weight saving makes the bike more nimble and it certainly feels it out on the trail.

You can choose between 5 frame sizes – extra small , small , medium , large and extra large .

The geometry of all the frame sizes allows for a good level of clearance to get up and over obstacles and you get a decent planted feeling through the back wheel – good for the speed you want in a versatile commuter and trail bike.

It isn’t ultra aggressive in its layout, but you can move at a fair lick and it feels fairly light to manipulate, despite the overall weight. The bike feels well grounded and it provides a comfortable riding experience.

The Trek Powerfly 5 has a big old Bosch PowerTube battery, which can kick out 625Wh . It’s a sizable partner for the bike and gives you a large old range, which takes away any real range anxiety.

We pumped out well over 100km on one charge, without ever having to feel nervous about the amount of battery we might have left. The bike is made for long distance riding and when you couple that with the comfortable geometry, you can happily spend hours upon hours in the saddle.

When you do run out of battery you aren’t waiting all day for it to juice back up again – you can get back up to full charge from dead in around 5 hours and it takes less than half of that to get up to 50% charge.

The battery is secured neatly into the downtube of that sturdy aluminium frame and it’s simple to click in and out for charging. Hassle free all around in the battery department – something we love to see.

You have power in the bike’s name and the Trek Powerfly 5 doesn’t disappoint in the motor department. It’s paired with the excellent Bosch Performance CX motor , which throws out a chunky 85Nm of torque.

That’s enough to make light work of any climb you put in its way and the respectable overall bike weight means it dances up the hills. Despite having a lot of torque in the tank the motor doesn’t feel aggressive in its output, it works intuitively to release in a natural way and it feels measured.

There’s no upsetting lag or overshoot as you release off the assistance, so you feel in control throughout. You get 4 modes of assist – Eco , Tour , Sport and Turbo – with the Turbo offering a seriously punchy level of assist for the toughest stretches of your day’s ride.

ℹ️ You don’t need to use the Turbo mode a great deal. It’s useful for the very trickiest inclines, but if you use it too much you’ll find it sapping your battery quite quickly. Use it sparingly.

We love the Bosch Performance CX and it’s a brilliant accompaniment to this bike.

Motor Display

The Trek Powerfly 5 comes with the Bosch Purion display . It’s mounted on the handlebars and has an easy-to-use controller to flip between data.

There are pros and cons with the Purion; you get a range estimation in kilometres, which is certainly helpful while out on the trails. However, the actual percentage of battery left isn’t shown – a real oversight.

Instead, you get a series of lights which indicate a range of battery percentage left and it isn’t quite exact. Fortunately, the battery is a big old beast and you never really have to worry too much anyway, but we think an exact figure would be much better.

You can also flip between a few other data options, including speed and the distance you’ve ridden so far.

The Trek Powerfly 5 is a hardtail , so doesn’t have any rear shocks, it only has a travel at the front end. Depending on the frame size you go for will dictate how much travel you get in the forks, which are supplied by RockShox, with their Recon Silver RLs fitted.

The extra small frame comes with 80mm of travel , whilst the small, medium, large and extra large options come with 120mm of travel . This bike isn’t made for the wild drops and monster descents, so don’t expect it to – it’s made for longer distance, multi-terrain riding, on flatter land and it has a setup capable of exactly that.

The hardtail means you always have a good level of traction at the back end to pick up speed and it doesn’t bounce around. The minimal travel in forks allows you to take a few lumps and bumps, without any worry, but it isn’t made for the seriously chunky stuff.

Wheels/Tyres

The Powerfly 5 comes with varying wheel sizes depending on the frame size you choose. The extra small and small comes with 27.5in, meanwhile the medium, large and extra large come with 29inchers at both the front and the rear.

The wheels are Bontrager Kovee Comps, with Bontrager XR3 Comp tyres . They’re a sturdy pairing, which offer strength and stability, capable of long distances and feeling comfortable throughout.

You also have some toothy tyres, which can offer the traction you need for the speed you want to pick up – but you don’t feel weighed down, the tyres offer decent dirt shedding on the hard packed bits.

The Trek Powerfly 5 comes with Shimano MT4100, 4-piston hydraulic disc brakes .

These aren’t the most powerful Shimano components out there, but they offer enough stopping power for the style of riding the bike is made for – let’s be honest, this isn’t made for super-sendy drops and lines.

The Trek Powerfly 5 is fitted with a 12-speed Shimano Deore M6100 drivetrain – a solid accompaniment, which offers reliability and ease of use. Quick and smooth shifting – exactly what you want over long distances.

A fairly priced e-MTB. The Trek Powerfly has outstanding electrical components and offers a brilliant ride experience. It’s pitched fairly in the market.

How Does it Compare?

Another challenger in the electric hardtail market is Specialized’s Turbo Tero 5.0.

Our Trek Powerfly 5 is 0.2kg heavier, so very similar, but offers a slightly smaller battery – with the Specialized coming in at 700Wh over our 625Wh.

Specialized has their custom 2.2 motor fitted, which offers 90Nm of torque – 5Nm more than our Bosch battery. However, the Bosch electrical components and their relationship between each other are superior in quality and ride experience.

The Specialized motor display is far more advanced than our Bosch Purion display – which could be fixed if Trek go for one of the other displays in Bosch’s armoury.

You get 110mm of travel on all frame sizes on the Turbo Tero 5.0, which is more consistent than the varying amounts of travel on our Trek bike – with both choosing RockShox as their partner in this department. Both setups do the trick.

Both drivetrain and brake setups also work we;, with Specialized choosing SRAM components and Trek gunning for SRAM. Price is a big factor in this comparison – the Trek Powerfly 5 comes in $1,600 cheaper – which for us puts it in pole position in this comparison.

The bikes aren’t too dissimilar, but you have a huge saving.

Final Thoughts

We’re big fans of the Trek Powerfly 5 and very impressed by its price. You don’t often get many bargains in the e-MTB world, but we think Trek has successfully managed to offer a bargain here.

It’s a big range and versatile bike, which offers an excellent ride experience and some top components, but at a fraction of the price to some of its competitors. For a bike which is designed for long distance, you want to feel comfortable up top and this bike offers it.

The electrical components are outstanding and the other aspects are solid – it’s only let down by the display. That’s an easy fix, though, by replacing the display for one of the other top Bosch displays. And in any case, it’s still by no means the worst display in the world.

A big congrats to the team at Trek – we think this is right up there among the best e-MTB hardtails for mixed terrain and commuting. Now give it a spin.

Up hill or down, ebikes take an absolute beating, so the new Trek Powerfly 9 has a beefed up the parts package to handle the additional abuse.

Suspension, brakes and tyres are all on point. New battery layout is neat and easy to use.

Could have more generous reach measurements and shorter stems on all sizes.

Trek Powerfly FS9 Equipped review

An assisted full-suspension, big-travel commuter?

Russell Burton / Immediate Media

Russell Burton

Comfort; range; stability

Expensive, especially if you’re considering leaving it outside the local shop

The FS9 is top of Trek’s four-model Powerfly Equipped range of electric bikes designed to combine practicality for commuting with the off-road fun of the best mountain bikes .

Its specification, which combines a long-range 625Wh battery, a Bosch Performance 250W motor and a full-suspension setup with powerful four-piston brakes, is sending a message that it won’t flinch when the going gets tough.

Trek Powerfly FS9 Equipped specifications

At first glance, all that off-road tech seems at odds with the bike’s more sedate features, which include integrated full-length mudguards, a kickstand and built-in lights.

Trek’s promo video shows the sort of shopping trip we all wish we had, with a route mixing road and scenic dirt track, and I approached my first ride on the Powerfly hoping this could be the commuter bike of my dreams .

The strong Bontrager Line Comp 30 wheels, shod in chunky 29x2.4in tyres, the SR Suntour Zeron 35 120mm suspension fork and RockShox SID Luxe Select rear shock are pulled from the mountain biking world.

It’s a combination that would normally be compromised by its weight for commuting, but in pairing it with an 85Nm motor so powerful as to be unbothered by extra heft, Trek has managed to optimise the Powerfly for the commute.

And who wouldn’t want comfortable, grippy tyres, powerful brakes and plush suspension?

That suspension was something that gave me pause for thought before testing – can a full-suspension machine with a mountain bike heritage be efficient on the road? Yes. Keep reading to find out how.

Trek powerfly fs9 equipped battery life.

Not that I have experienced problems with battery range, regularly riding 70-90km, including over 1,000m of climbing, and arriving home with plenty in the tank.

There are four modes – Eco, Tour (eMTB Lite), eMTB and Turbo – and even on longer routes, I didn’t have to drop to Eco to preserve battery life, riding mainly in Tour mode with short boosts of added power.

Trek Powerfly FS9 Equipped ride impressions

I’d not used this fork before and it surprised me – in a good way. It's stiff enough to support the bike’s weight, it doesn’t bounce when you’re pedalling hard on the road, yet it sucks up the chatter of poor tarmac.

Transitioning to forest tracks, it smooths the ride so you barely lose speed over rocks and roots.

The rear shock is unusually positioned behind the seatpost, but is protected by the full mudguard. It absorbs the bumps but, as with the fork, doesn’t bounce. It plants the back wheel into the ground in a way that feels secure and maintains grip right through corners.

That security and control is underlined by the Shimano XT four-piston brakes, which are strong enough to slow the weight of the bike quickly and smoothly without locking.

The Powerfly FS9 Equipped seems to love going fast in a straight line the most, and the distances I’ve ridden on a mix of roads and tracks are testament to its comfort and ride appeal.

It does, however, have limits on more technical terrain.

I’ve ridden it over the same terrain I use for testing the best electric mountain bikes , and there is no comparison – it doesn’t have the handling finesse for tight, twisty stuff.

If you have the skills, yes, you’d do it, but probably not in quite the style you’d like.

Sweet-spot pedalling helped by smart modes

The 10-51t gearing range is huge, but still I found myself succumbing to the temptation to stick to a few of the lower gears and default to switching between power modes.

It’s a habit that doesn’t get the most out of you or the motor, so I played with the onboard app and discovered it gives a readout for optimum cadence, turning green when you get it right.

That’s all to the good, though the weight means it’s not a bike you want to be caught out on without power. Moving between modes is quick and smooth, the motor picking up exactly where it needs to.

My only gripe is that when it tops out at 26km/h, the cut-off feels abrupt and the bike slows rapidly before kicking back to life. It’s not a seamless experience.

Accessories for the win

The mudguards have good clearance and keep off most of what gets thrown up, even from wet, muddy tracks.

In fact, I came to appreciate all the commuting-specific accessories more than I expected. A kickstand may not feel that exciting, but once I used this rather than propping the weighty ebike against a wall, I was converted.

The built-in lights are powered by the battery, so there’s no reason to get caught without working illumination. The sturdy rack will bear up to 25 kilos and is compatible with most panniers .

Trek Powerfly FS9 Equipped bottom line

The Trek Powerfly FS9 Equipped is an electric bike that makes you want to ride more – it allows you to take the more interesting routes less travelled on your commute and have fun on forest tracks at the weekend.

It would also be ideal for touring on long-distance tracks such as King Alfred’s Way in the south west of England, given its range, comfort and load capacity.

Embrace its niche and you’ll get the best out of this bike, and it could well get the best out of you as a rider – if you can afford it.

Anyone heard any rumors about a 2021 Trek Powerfly 5 full suspension?

New Trek Powerfly FS 2021 – introducing Trek’s brand new tour-oriented allrounder with the new Bosch Performance CX motor

Active Member

Wow... pretty interesting that those photos show that one can spec it with full fenders, rear rack and kickstand. This could go from singletrack MTB trails to commute with full suspension.  

I believe that is Trek's intent, an all-purpose bike for all occasions. I quite like it. Powerfly FS 9 Equipped - $6000 Powerfly FS 4 - $4600

Available only in Europe?  

I really like this design. 29x2.4 tires are very nice all around tires. Is there enough clearance for a second battery ?

Missouri71 said: Available only in Europe? Click to expand...

I see that Trek has these on their website now but who knows when they will be available....  

That Powerfly FS 9 looks to be on the heavy side but I’m guessing a great commuter  

Would this series make a good city bike with occasional use on gravel trails and gravel roads?  

I think this will be a very good trail/cross country eMTB. For on road it will work well and be very comfortable. It is a bit heavy, but probably due to full suspension and also aluminum rather than a carbon frame. That probably keeps the price down though. I like that it has a full 12 speed shimano XT drivetrain. The only issue for me, would be that I would prefer a class 3 speed motor like the allant, then it would be perfect, but I understand there decision to go with the CX motor. For the money, it seems to be a really good deal compared to say riesse and mueller FS bikes and you will get Trek service.  

Looks good but why only one color scheme? C’mon Trek!

Bulls Iconic Evo TR 2 Speed

Riese & Muller Delite GT Touring

There's also Frey CC , but it's 27.5 .  

The big difference is both of those have gen4 speed motors which is great. However for a little more money it seems the Trek Powerfly 9 has a much higher level component set and Trek will likely be easier to service due to there network, at least in the US. Seems Trek went for more off road climbing ability with the CX motor. On the road, for commute or just covering distance it’s easy to go 20-28mph, and it’s quite easy to hold these speeds on level ground with such strong motors. Having such a nice full suspension setup and its weight penalty but not being able go faster to really take advantage of the suspension damping seems odd. I guess they prioritized off road performance a bit more. Riess and Meuller have the FS commute bike benchmark except for their price. If Trek were to add a speed motor option, at this price and it would be a very attractive option to me  

So between the Bulls Iconic, Trek FS 9 and Moustache Semedi 27 who is going to be the winner. These are the 3 bikes I am considering. #1. Which one could I get soonest in Palm Springs CA? I noticed my LBS is listed as a Trek dealer #2. Which one will be the most dependable #3. Which one has the best reputation as far as warranty? #4. Is the Frey CC really in this league?

Trek Powerfly FS 9 Equipped in review – A new generation of E-trekking bike

With the Powerfly FS 9 Equipped, Trek have developed a unique concept that looks beyond conventional bike concepts and combines the best features of different worlds instead. Was the Powerfly FS 9 Equipped able to assert itself against the competition in our E-trekking bike group test?

That eBike is part of our big trekking eBike group test . There you can find an overview of the test fleet and all information on the latest generation of trekking eBikes.

Trek Powerfly FS 9 Equipped in review – Is this what the next generation of trekking bikes feels like?

It’s all a matter of balance: with the Powerfly FS 9, Trek have made it their mission to blur the boundaries between bike categories and combine the best of the eMTB and E-trekking bike worlds. Instead of prioritising particular riding characteristics, Trek’s full-suspension ebike was developed to blend supposed opposites and create a balanced and harmonious riding experience, both on- and off-road. To find out whether the concept actually works, we tested the flagship Powerfly FS 9 Equipped, which weighs 27.10 kg and retails for € 6,999. The upright pedalling position allows you to concentrate on the trail ahead and is pleasantly balanced, distributing the weight evenly between the hands and saddle – the perfect prerequisites for a great tourer! At the same time, the balanced weight distribution ensures good control over the front wheel and generates lots of traction at the rear. The Bosch Performance Line CX motor delivers plenty of power in all situations and is easy to modulate thanks to the progressive eMTB mode. Moreover, the Trek has a second progressive mode called eMTB-Lite, which is optimised to provide increased range. The intuitive handling makes it easy to lean the bike into wide corners and take advantage of the wide handlebars to dodge potholes and obstacles with quick and controlled turns. Although it’s not as playful as a trail bike, the Powerfly is great fun and easy to control on easy trails, getting you to your destination quickly and safely even when the route includes unpaved trail sections on challenging terrain.

Well-equipped for everyday life and excursions

The wide, high-volume 2.4” Bontrager LT4 Expert tires generate plenty of traction and feel predictable both on tarmac and loose terrain, inspiring huge amounts of confidence in all situations and only sliding out in muddy conditions. Shimano XT four-piston brakes with 200 mm rotors provide powerful and reliable deceleration. Even on long descents with a full pannier on the rack, they deliver consistent braking power and good modulation. While at 108 kg the Trek has a relatively low maximum payload, even with a 10 kg pannier on the rack it’s good natured and easy to manoeuvre, feeling significantly more composed than other bikes with a higher maximum payload ratings – i.e., the Kalkhoff Entice 5 Advanced+. The pannier rack features a practical MIK rail, which makes it easy to attach compatible bags and is approved for a 25 kg load. The Supernova MINI 2 headlight and E3 tail light look great and are powerful enough for night riding. Unfortunately, other accessories don’t live up to the otherwise high-quality spec of the Powerfly. The plastic mudguards are too short and can’t prevent mud from flying onto the person riding behind you and the kickstand makes a loud rattling noise.Trek-Powerfly-FS9-Equipped-Trekking-E-Bike-Test-Review-2021-mag-0007.jpg

Tuning tip: Bosch Help Connect plan with fall detection for solo adventurers

Stiff – Riding comfort onboard the Trek Powerfly FS 9 Equipped

The suspension of the Trek Powerfly FS 9 Equipped consists of a SR Suntour Zeron 35 fork and semi-integrated RockShox SID Lux Select+ shock, controlling 120 and 100 mm travel respectively. Although the numbers suggest a high level of comfort, the suspension is tuned for maximum efficiency which translates into a stiff and sporty rear end. On smooth tarmac, this converts each pedal stroke into efficient propulsion, without the rear end bobbing. Small bumps and vibrations are mostly dealt with by the high-volume tires while the suspension takes care of bigger hits, working actively and efficiently. As a result, the Trek is less comfortable than the Riese & Müller Homage but, in return, doesn’t feel as sluggish. The low-slung top tube and 150 mm Bontrager Line dropper post make it easy to get on and off the bike.

Propulsion first! The sporty suspension is tuned uncompromisingly for efficiency and riding fun, not for comfort.”

A smartphone as an on-board computer – The connectivity of the Trek Powerfly FS 9 Equipped in detail

One of the most striking equipment features of the Trek is the versatile Bosch SmartphoneHub. For short rides, this can be used without a smartphone. The basic 1.5” display shows all key data such as battery charge and speed. If you want other functions like navigation or fitness tracking, you can connect your phone to the SmartphoneHub via the COBI.Bike app and Bluetooth. While riding, the smartphone is firmly attached to a spring clip on the SmartphoneHub, where it can be operated via remote and charged via the hub itself. The COBI.Bike app offers a wide range of functions including voice navigation. If you tend to ride a lot on your own, you should take a closer look at Bosch’s Help Connect function (€ 4.99/month or € 39.99/year) with fall detection mode. This can notify your local emergency services in the event of a crash and is currently available in 11 European countries.

Quick off-road blast or long weekend ride? The Trek Powerfly FS 9 Equipped doesn’t say no to either!“

This is what the future of trekking looks like – The Trek Powerfly FS 9 Equipped in detail

Even whilst stationary, the Trek Powerfly FS 9 Equipped cuts a damn fine figure. Particularly striking are the sporty silhouette with its low-slung top tube and the elegant finish with its dark accents. Unfortunately, the chaotic cable management in the cockpit area spoils the otherwise tidy look. The Bosch Performance Line CX motor is neatly integrated into the frame and protected by a skid plate, while the 625 Wh battery is integrated into the down tube and can be easily removed to the side. The battery cover features Trek’s trademark carrying- handle while the battery cover and charge-port cover on the seat tube are both painted to match the colour of the frame. The charge port cover is easy to open and closes automatically – awesome! Not only the frame but also components like the handlebars, dropper post and BontragerLine Comp 30 wheelset, which Trek also use on their other performance-oriented eMTBs, make a great impression. In the smaller XS and S sizes, the Trek Powerfly comes with smaller 27.5″ wheels while all other sizes roll on big 29” wheels.

Trek Powerfly FS 9 Equipped conclusion

The Trek Powerfly FS 9 is exceptionally versatile and covers a wide range of applications, giving the concept of trekking a whole new meaning. The finely-tuned suspension and balanced pedalling position ensure sporty yet predictable handling and top riding fun while inspiring huge amounts of confidence on long off-road expeditions. The everyday equipment makes daily commutes and weekend trips more comfortable. The elegant look rounds off the successful concept of the Trek Powerfly FS 9, which comes out on top in our E-trekking bike group test, securing the coveted Best in Test.

Rudolf Fischer

In his previous life Rudolf was a dab hand at promoting innovation, putting his brain behind big-ticket patent assessments that easily ran into six-or-seven-plus figures. These days, the self-confessed data nerd’s role as editor at DOWNTOWN and E-MOUNTAINBIKE is no less exciting. Given his specialism in connectivity, Rudolf’s often placed on the front line of future mobility conversations, but he’s also big into testing new bikes–both on the daily as a committed commuter and intensively for our group tests. The business economist graduate is as versatile as a Swiss penknife, and that’s no hyperbole. Away from two wheels, his background in parkour means he’s a master of front, side and backflips, plus he speaks German, English, French, Russian and a touch of Esperanto. Japanese remains woefully unmastered, despite his best home-learning attempts. Good to know: Rudolf’s sharp tongue has made him a figure of fear in the office, where he’s got a reputation for flexing a dry wittiness à la Ricky Gervais... interestingly, he's usually the one laughing hardest.

Trek Powerfly 5

• Price: $4,199
• Frame: Alpha Platinum Aluminum

Rating： (4.8/5)

Introduction

When fans asked for a review of the Trek Powerfly 5, as someone who likes pure mountain bikes, I had little interest in the Trek Powerfly 5 off-road e-bike. But I was stunned when I saw its sturdy body, which is really a rare heavyweight in my review.

To be honest, when I saw it, I thought of technical climbs and less-populated trails, and I changed my mind and wanted to review such a bike. We can see the Trek Powerfly 5 with a premium Alpha Platinum Aluminum frame, a wide-range SRAM SX Eagle 1×12 drivetrain, versatile Bontrager XR3 Comp29x2.30″ tires, and a high-end Bosch Performance CX motor, we were blown away by the Trek Powerfly 5’s performance on technical climbs and thrilling descents.

Over four months of our review, the car accompanied me on challenging trails like Whistler Mountain Bike Park, traversing about 40 miles of desert terrain. Not only did I feel the car’s superior climbing performance and athletic ability on loose terrain, it also gave me an intuitive adrenaline rush.

Really awesome. It’s that free-spirited climb, like blending in with the trail, really got me hooked on the Trek Powerfly 5.

Below we break down the climbing and descending performance of the Trek Powerfly 5 as well as general ride, key features, components and specs, and other versions in the range.

Trek Powerfly 7 Review – High-End Battery

In my experience, in general, full-suspension mountain bikes are better at climbing, and with the front and rear shocks, the damping effect will be good, making the ride more comfortable. The car’s climbing comfort probably can’t match it. Yet on this technically difficult climb, the Trek Powerfly 5 excels at the same price as a full-suspension bike or XC.

The Trek Powerfly 5 came across as bulky due to its bulky body. The Powerfly 5 weighs 50.70 lbs (with tubes), which is unwieldy for me. I can’t imagine how I’d be able to get up there without starting a climbing ride. But actual riding gave me the answer.

On a trail like this one at Whistler Mountain Bike Park, I started doing climbing reviews. The climbing trail has plenty of sharp rocks and mounds that bulge upwards.

But I have no fear with the Trek Powerfly 5. Its SRAM SX Eagle 1×12 drivetrain, high-end Performance Line CX motor, and RockShox Recon Silver RL 120mm fork travel allowed me to reach unimaginable speeds when climbing, which is better than XC at the same price.

Also, we did rides on steep trails after the rain, but the results were not as good as we thought. Some people feel that the 29×2.60″ tires are a little floating, which may be a hindrance for beginners, but I have no obvious feeling, and even I think the driving force of the tires is very fast, and it can follow the trails tightly.

Overall, I think the Trek Powerfly 5 has a lot of power on the climbs, and its high-end Performance Line CX motor gives me enough power that it makes me enjoy climbing more.

I like the sprint on the descent, but I also value safety. The Powerfly 5 excels on the climbs, but I’m concerned that the weight of its body will introduce too much inertia when descending and it will hinder the descent. “everything is possible”.

The Powerfly 5 also exceeded my expectations on the descending. The Powerfly 5’s Bontrager XR3 Comp 29×2.30″ tires provide plenty of traction, and the prominent tread pattern adds to the tire’s grip.

Its RockShox fork and Solo air spring play a big part in the descent. The 120mm-travel RockShox fork encountered cliff-like jumps during the descent, and it provided responsive cushioning that allowed me to dampen vibrations even when I jumped from high places.

The air spring is more labor-saving and convenient while reducing weight. Not to mention, the power provided by the Performance Line CX motor and the braking of the Tektro HD-M275 hydraulic disc.

When I challenged the descending trail with the Powerfly 5, the ground was slippery due to the accumulation of water on the ground, and the fallen leaves created unforeseen obstacles.

In fact, the speed performance of the Trek Powerfly 5 is not as good as before, but its stability is on full display here. I think stability is a measure of bike quality in situations like this, and the Trek Powerfly 5 gives me a sense of security.

All in all, the Trek Powerfly 5 is good enough for me in both climbing challenges and descending performance, and the price is reasonable.

General Riding

My cycling started with my family. My father was an amateur cyclist and he had many beneficial influences on my riding.

I know he has a Powerfly 5, but I really never paid much attention to it. When my dad learned that I was reviewing the Powerfly 5, I had a rare family time with my dad after a long time, and discovered how important the Powerfly 5 is to my dad and why he loves the Powerfly 5 reasons.

I still had a little leg problem due to hard work when I was young, and my cycling dad couldn’t go on long rides. The drive provided by the Powerfly 5’s Performance Line CX motor solves that problem.

The Powerfly 5 was there for my dad, whether it was for the usual bodybuilding, commuting, or even climbing the slightest incline.

The versatility of the Powerfly 5 was exceptional with my dad, and I seem to have felt the designer’s deepest mind here. The Powerfly 5 is not only our best friend, but also a great companion for those who love to ride, but can’t ride very far.

If your family loves the Powerfly 5 too, take them to experience the Powerfly 5.

Main Feature

Trek powerfly 5 frame.

The Trek Powerfly 5 has an Alpha Platinum Aluminum frame with an overall weight of 50.70 lbs (with tubes), but I wouldn’t think it’s a frame issue, since aluminum is light and strong. We can notice that the Powerfly 5 doesn’t have a single superfluous line as a whole, thanks to Control Freak’s clean internal routing.

In addition, the removable integrated battery (RIB) also brings us enough driving force and convenience. Not only that, the proper frame space makes my ride more comfortable, and the two water bottle mounting holes make it easy for me to carry enough water.

Even when riding in harsh conditions, I think the Powerfly 5 is a reliable enough comrade-in-arms.

The ride comfort of the Trek Powerfly 5 I think has a lot to do with geometry. The body-friendly geometry not only makes it look balanced and beautiful but also enhances rider comfort.

The Trek Powerfly 5’s steep seat tube angle (LG 71.7°) allows the rider to maintain a comfortable upright ride while increasing pedalling efficiency. Its slack head angle (LG 67.7°), while perhaps making the bike’s steering less responsive than the tight head angle, made it easier for me to descend.

Plus, the Powerfly 5 has the right chainstay length (45.5mm) to stay stable on the descents and help on the climbs. Powerfly 5 Proper Reach (LG 42.7cm) allows you to achieve a good balance between the front of your body and your arms without your arms getting sore.

However, if you ride on bumpy terrain for a long time, it will still make your arms feel tired. The comfy Powerfly 5, at this price point I think it’s an A.

If you value not just performance but comfort, you can try the Trek Powerfly 5.

Components and Specifications

Sram sx eagle 1×12 speed.

As we all know, SRAM has almost taken the shifting system of mountain bikes by storm with the Eagle series of 12-speed groupsets in recent years. Almost every mountain bike I’ve seen with a 12-speed is using SRAM.

The SX Eagle 1×12 speed we saw used in the Powerfly 5, some thought it might not be as good as the NX. The SX doesn’t cost much, and in my riding experience, it’s smooth and responsive too quickly.

In addition, the 12-speed range is sufficient for climbing or commuting, and the larger gear ratio range of 11-50t allows you to quickly change to the appropriate gear in different situations.

The only thing I feel like a bit of a complaint about the shifting system is that it’s a little heavy, wish it could have been replaced with lighter and better gears.

Tektro HD-M275 Hydraulic Disc Brake

I prefer Shimano to the Tektro HD-M275 hydraulic disc, but that’s not to say the Tektro HD-M275 is bad. The Powerfly 5 Tektro HD-M275 hydraulic discs are lighter in weight than mechanical discs and are much gentler on braking without harshness.

While reviewing the Powerfly 5, I did a brake test. Riding on muddy and twisty country trails and going fast on the road after the rain, its braking remains extremely stable. If you like safe, stable, and smooth braking, I think you’ll be interested in the Powerfly 5.

Bontrager Commuter Comp Bicycle Saddle

The moment I sit in the seat, I feel what is called comfort. From the appearance, we can clearly see that the middle of the seat is empty, which will be very breathable. The Trek Powerfly 5’s saddle combines a full open cell with air foam and dual-density shell to give me soft comfort and support while riding.

Not only that, the material is more durable, but its cover material protects the saddle’s dual-density shell and air-foam construction, and it’s even waterproof. Provides lasting comfort no matter where you ride.

Plus, the deceptively simple integrated Blendr mount makes it easy to add Bontrager Flare taillights to your needs. Even when riding in the evening, it can be noticed by others and not bumped into people. Of course, this possibility is almost 0.

Bontrager XR Endurance Comp Grips

Many people will ignore the role of the grip, we must know that we rely on the grip to control the direction. The Trek Powerfly 5’s grips are literally in the top 5 of the bikes I’ve reviewed in terms of looks and fit.

Not only does the XR Endurance Comp Lock-On Grip feature an ergonomic supportive shape for great support without sacrificing your comfort, but it also lets you go further.

Additionally, the pattern protects your palm (because of the padding) and your fingers stay in place at all times. I’ve had a bruised palm from grip issues a lot of the time on long rides, but the grips on the Trek Powerfly 5 not only alleviated that symptom, but made my rides easier.

Bosch Performance CX Motors

The Trek Powerfly 5 isn’t your average hardtail mountain bike, it’s electric, and that’s what the Performance Line CX motor has to say. The high-end Performance Line CX motor is networked with other components on the e-bike via an intelligent system, and thanks to the eBike Flow app, I can easily keep track of the bike’s trajectory.

Some people may think how can electric motors achieve the effect of fitness? But the truth is that the Trek Powerfly 5 does improve your health (my dad is one example).

You can appreciate the convenience brought by technology, the support of intelligent systems provides better protection for you and your e-bike, and the enhanced control brings you more riding pleasure.

Trek Powerfly 5 Tires – Bontrager XR3 Comp MTB

The tires of any bicycle are like the steps that carry us forward. The Trek Powerfly 5’s Bontrager XR3 Comp 29×2.30” mountain bike tires are not only for mountain trails, but their excellent traction kept us going even on steep hills.

Its versatile tread also gripped the corners firmly when I faced sharp turns. Whether it’s on a quick descent or a steady ascent, the Trek Powerfly 5’s tires are on full display.

Other Versions of Trek Powerfly 5

For a more comprehensive review of the Trek Powerfly 5, we also looked at the 2019 Trek Powerfly 5 and 2018 Trek Powerfly 5. After a comprehensive comparison, we found that although the Trek Powerfly 5 is a bit more expensive, its component upgrades are obvious to all.

First off, the 2018 and 2019 Trek Powerfly 5’s drivetrain is 1×10, and the Trek Powerfly 5 is 1×12, with a wider shift range without ignoring shift comfort. Second, the 2018 and 2019 Trek Powerfly 5s have Shimano brakes that I like, but they’re rudimentary Shimano brakes, and I’m a little disappointed at this price.

Finally, with the advancement of technology, the components and motors of the Trek Powerfly 5 have been upgraded. Even if the price will be a little more expensive, I am still willing to pay for the Trek Powerfly 5 from the sense of technology and applicability.

What do we like about it?

• The speed range of 1×12 can be applied to more situations.
• The high-end Performance Line CX motor provides plenty of assistance, allowing you to experience more riding pleasure.
• Body-fitting geometry makes you more comfortable while riding.
• It is one of the great gifts for your family.
• Comfortable grips make you fall in love with riding.
• The comfortable saddle makes me reluctant to get off.

What do we not like about it?

• Some people may think that the body is too bulky.
• The color selection of the car paint can be more abundant.
• What is the frame material of the Trek Powerfly 5?

The frame of the Trek Powerfly 5 is Aluminium.

• What is the drivetrain of the Trek Powerfly 5?

The drivetrain on the Trek Powerfly 5 is an SRAM SX Eagle, 12-speed.

• What is the fork travel on the Trek Powerfly 5?

The Trek Powerfly 5 has 120mm of fork travel.

Comparison Chart

Trek powerfly 5 vs trek powerfly 7.

We can see that the fork travel is different between the Trek Powerfly 5 and the 2017 Trek Powerfly 7. Although only a short 20mm difference, this makes a huge difference in the actual riding experience.

The Trek Powerfly 5’s 120mm fork travel has better cushioning and shock absorption. Also, the 2017 Trek Powerfly 7Shimano Deore M8000 XT 1×11 has a smaller transmission range than the Trek Powerfly 5 SRAM SX Eagle 1×12.

In actual riding, I prefer the smooth shifting of the SRAM SX Eagle 1×12 and the wide 11-50t range. I think it’s important to get the Trek Powerfly 5 for $200 more, which is more than enough for me.

Trek Powerfly 5 vs Giant Stance E+ 2

In fact, the Giant Stance E+ 2 is a full-suspension off-road electric bike with 130mm of fork travel and 120mm of rear fork travel. Like most full-suspension bikes, it’s well damped on both descents and climbs, and its slack head angle (67°) makes it easier to descend.

However, the Giant Stance E+ 2 drivetrain is a Shimano Deore, 1×10 speed, and I think its drivetrain could be improved a bit at this price. Also, its single paint color feels too little choice (although this balsamic green looks good too).

Let’s take another look at the Trek Powerfly 5, which has a 1×12-speed drivetrain with a wide range of speed options that allows me to experience the feel of different speeds. The Trek Powerfly 5 also has more paint options in three colors.

Not to mention that the Trek Powerfly 5 is $201 cheaper than the Giant Stance E+ 2. If you’re after value for money, you can try the Trek Powerfly 5.

Trek Powerfly 5 vs Norco Fluid VLT A2

When I saw the price of the Norco Fluid VLT A2, I thought it would most likely be a carbon frame bike. But it’s an aluminum frame, although aluminum isn’t bad.

It is undeniable that the Norco Fluid VLT A2 is a full-suspension electric bike. It has a front fork of 140mm, a rear fork of 130mm, and a dropper post configuration, which makes the Norco Fluid VLT A2 full of shock absorption. However, the gearing of the Norco Fluid VLT A2 1×10 gave me a bit of a gripe, and I wish it could be improved.

After all, the 1×10 transmission seems a bit outdated now, of course, this is not to say that the 1×10 is bad, but at this price, I think the Norco Fluid VLT A2 can do better. As many of you who know the Trek Powerfly 5 know, it has a 1×12 transmission.

Although not much, there is still a big difference in the actual riding experience. Not only that, the charger of the Trek Powerfly 5 is a Bosch compact 2A (100-240V) charger, which allows it to supplement energy at a voltage of 100-240V so that it cannot be freely charged due to voltage limitations.

While the Norco Fluid VLT A2 is a little better than the Trek Powerfly 5 in terms of braking, the Norco Fluid VLT A2 isn’t bad either, with stable braking even in the rain. At this price, I think the Trek Powerfly 5 is adequate.

If you’re looking for a $1290 cheaper Trek Powerfly 5, I think it’s a no-brainer.

Trek Powerfly 5 vs Transition Scout Alloy GX

Looking at the Transition Scout Alloy GX full suspension trail bike, we must mention its 140mm chainstays, 150mm fork travel, and its dropper post. This allows it to adapt to more rough terrain and allows for a more comfortable ride.

Not only that, but the Transition Scout Alloy GX also has a 1×12 drivetrain, and its TRP DH-R Evo brakes very smoothly. In fact, my only complaint is the high price, and I think a carbon fiber frame might make me more willing to pay for it.

Not only is the Trek Powerfly 5 $800 cheaper, but it’s also 1×12 speed. Some might think its transmission isn’t advanced enough, but in this price range, it’s adequate and I feel very stable in terms of braking.

If you’re after value for money, you can try the Trek Powerfly 5.
