Trek Powerfly 5 Review

trek powerfly 5 review

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 .

trek powerfly 5 review

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.

trek powerfly 5

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!

trek powerfly 5 pictured on bodmin mor

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

bosch powertube 625 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.

trek powerfly 5 with sram 12 speed gearing

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.

trek powerfly 5 2021 specs

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

trek powerfly 5 2021 specs

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.

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

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  

Johnmj1

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

misteracng

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!

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  

Taylor57

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?

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.

New in this Powerfly generation are an advanced removable battery system, carbon fiber frames, purpose-built ebike components and the 150mm of travel in the LT model. - Mtbr.com
