Trek Powerfly 4 Gen 4 Review: Takeaway
The Trek Powerfly 4 is the cheapest electric mountain bike made by Trek. This doesn’t take away from its great components and rideability, though. It’s an eMTB designed for lighter trail riding with its larger wheels that smooth out the bumps on the rough spots. Relatively light yet powerful, the Trek Powerfly 4 Gen 4 is an ideal electric mountain bike that doesn’t break the bank.
Ideal for...
E-bike overview.
The Bosch Performance CX motor gives a real kick with up to 85Nm of torque, meaning that you can pull away on a steep and muddy hill with confidence. Power delivery is smooth so you won’t spin the rear wheel should you push too hard. The Bosch smart system offers enhanced ride control with navigation and activity tracking via the eBike Flow app.
Packaged with the Bosch Performance CX motor, is their Walk Assist mode that helps push your e-bike up those tough hills you’re bound to encouter. The LED remote let’s you enable Walk Assist and control the level of pedal assist you need. The LED lights are bright and easy to see, even in bright sunlight.
One thing that Trek does with this electric bike is fit different equipment to different-sized machines. For example, on the XS and S framed machines, it has a 27.5” wheel size, while on the M, L, and XL sizes have a 29″ wheel. The frame on the smaller e-bikes are also slightly different, offering a curved top tub for sizes XS and S, while frame sizes M, L, and XL have a straight top tube.
Trek has thought about everything, not surprisingly. Rack and kickstand mounts are readily avilable, as well as an integrated speed sensor for those riders looking to use the PowerFly 4 as more of a trekker than a day-rider trail e-bike.
Reasons to Buy
If you want an electric bike but don’t want to empty your bank account, the Trek Powerfly 4 Gen 4 is a very good machine to consider. At the lower end of the premium spectrum, the Trek Powerfly 4 will be worth every penny when it comes to an electric mountian bike that will look after you on the road or trail.
Designed not to embarrass you on the trail, it works well on longer cross-country rides. Its battery will be good for a 35-mile ride on tougher terrain, and the power of the Bosch Performance CX motor will leave you breaking a sweat only if you’re going easy on the battery.
When it comes to speed control, the electric bike won’t let you down even on steep tracks in wet conditions with its Tektro hydraulic brakes, and on 203mm rotors, they won’t fade even if used a lot.
Things to Consider
If you want a genuinely inexpensive electric mountain bike, there are others like the Rad Power brand of electric bikes, but few pack as many high performance components as the Trek Powerfly 4 Gen 4. This isn’t the cheapest eMTB out there, but it is very inexpensive for a high-end machine.
Specs & Components
The specs above come from the manufacturer and may vary from what you’ve experienced. Notice something that needs correcting? Let us know .
Offering up to 85 Nm of torque, the light but punchy Bosch Performance CX motor delivers the power you need for riding off-road, including rapid direction changes and tackling steep climbs as you journey around the woods or mountain.
Its Bontrager XR3 Comp tires won’t go quickly on hard, flat surfaces due to higher rolling resistance, but this isn’t what the Powerfly 4 is about — it’s about fun in the mud and on loose surfaces. As such, the motor won’t achieve great flat-out speeds, but it’ll more than make up for it in raw power over the rough stuff.
The 500 Wh battery on the Powerfly 4 will give you a good day out on singletrack and a reasonably long day in the saddle on an off-road adventure. However, there’s no option for a range extender, so if you’re looking for more than 35 miles per charge, choose an eMTB with a range extender or a 625+ Wh battery.
Leaving your gear at a base while doing singletrack will give you more range, but if you’re carrying your pack on an adventure, this will eat into your mileage. Muddy terrain and foul weather can impact range, too.
Sat in a trekking position, you’ll use your upper body to shift your weight according to riding conditions. This could mean you get tired in your arms, chest, and shoulders after a long ride.
Sizes XS and S in the Trek Powerfly 4 range come with 27.5” wheels, while sizes M, L, and XL come with 29” wheels. Either way, they’ll smooth out the rough terrain.
The XS version of this eMTB hardtail electric bike comes with an 80mm travel SR Suntour fork, while all larger sizes have a 120mm travel fork. Both are well-suited to rough terrain.
Though Trek offers a lifetime warranty on the frame, if you haven’t looked after this e-bike, the warranty may be voided.
Clean the bike and oil its working parts after every ride. Keep an eye on chain stretch — change it when it gets to 1 mm per link, and look out for bent/broken teeth on the cassette and front chain wheel. Also, keep an eye on brake pads and hydraulic fluid. Though the Powerfly 4 is waterproof to an extent, take care when it comes to river crossings, as it isn’t designed for complete immersion!
Being a serious electric mountain bike, the Trek Powerfly 4 also looks the part. The clean lines and nice shapes of the frame along with its overall geometry combine to make for a good-looking eMTB.
The choice of colors is good too, from the loud red and black scheme to the muted gray and black. Overall, this bike looks like it means business when thrown about the tracks and trails.

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 2 trek powerfly 5 review](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-2021-2-scaled-e1625324645167.jpg)
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 Review 3 trek powerfly 5](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-review-e1625324701420.jpg)
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!
![The Trek Powerfly 5 is a stunning bike! trek powerfly 5 pictured on bodmin mor](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-2021-11-e1625324850142.jpg)
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
![Trek Powerfly 5 Review 5 bosch performance line cx motor as fitted to the kona electric ute](https://www.ebikechoices.com/wp-content/uploads/2019/11/Bosch-Performance-Line-CX-ebike-motor-e1593164966836.png)
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.
![Trek Powerfly 5 Review 6 bosch performance line cx motor](https://ebikechoices.com/wp-content/uploads/2021/07/Bosch-Performance-line-CX-e1625326540304.jpg)
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
![Trek Powerfly 5 Review 7 bosch powertube 625 battery](https://ebikechoices.com/wp-content/uploads/2019/11/Bosch-Powertube-625-battery.png)
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 Review 8 trek powerfly 5 with sram 12 speed gearing](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-2021-1-e1625328291819.jpg)
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 occasion](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-2021-5-scaled-e1625328371390.jpg)
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 occasion](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-2021-4-scaled-e1625411263208.jpg)
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.
![Trek Powerfly 5 Review 11 trek powerfly 5 white](https://ebikechoices.com/wp-content/uploads/2021/07/Trek-Powerfly-5-White-Gunmetal-e1625412475124.jpg)
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 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.

Trek Powerfly 2019 Review – now with a carbon frame and fully-integrated battery
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-50-2000x500.jpg)
The Trek Powerfly has become a true eMTB classic and has undergone several updates over the years. To keep up with the competition for the new season Trek equipped the latest version of their popular bike with an integrated battery and also introduced two fine carbon versions of the Powerfly LT. Here you’ll find all the details!
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-51-1140x760.jpg)
A few years back Trek did a great job and gave the Powerfly a well thought-out and very well balanced geometry — which once again fully convinced us in our latest test . Sure there are more nimble bikes on the market but the new Powerfly strikes a great balance between uphill and downhill performance. For the new season Trek sticks to the proven geometry and rear-end of the previous version but ads a fully integrated, removable battery. On top of this the new model is available in two carbon versions and the spec has been optimised too. All Plus models are now rolling on sturdy, grippy Bontrager XR4 tires and all Powerfly LT models feature powerful four-piston brakes.
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-16-1140x760.jpg)
Here are the highlights of the 2018 Powerfly line up at a glance:
– New fully integrated, removable battery – Two Powerfly LT carbon models – eMTB-specific fork on all Powerfly LT models – Four-piston brakes on all LT models – Bontrager XR4 tires on all Plus models – More colour options – SRAM Eagle groupset on some models – Robust RockShox Revelation on the Powerfly FS7 model – Updated Bontrager Line dropper – Powerfly Sport-Hardtail with lights and mudguards
Trek RIB: probably the best fully-integrated and removable battery on the market
There is a vast choice of eMTBs with integrated battery on the market but only a few systems are thoroughly thought-out and refined down to the last detail. Some bikes come with super long batteries, on others the battery can’t be locked and can only be removed with the help of tools. And then there are systems made up of several parts (battery and cover). A battery can weigh up to 4 kg so when you remove it you have to be really careful not to drop it on the floor and break it.
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-9-1140x760.jpg)
You can tell that the engineers at Trek gave the development of the RIB system (removable integrated battery) a lot of thought. The battery and the cover are one solid unit and the 500 Wh Bosch Powertube battery can be removed to the right hand-side. The system makes sense as most of us tend to lay their bike on its left side to avoid damage to the rear derailleur. Once you released the battery with the key it will pop out by a few centimetres; after depressing the big button you can remove the battery completely. An integrated handle makes the whole procedure easier – what an ingenious system! In addition the new integration allows you to place a bottle cage and a large drinking bottle in the main frame triangle.

The new carbon frame allows for less weight and sleeker integration
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-50-1140x760.jpg)
The new carbon frame proves just how much Trek believed in the geometry of the previous Powerfly LT model. The Americans could have revised the geometry for the latest update of the Powerfly but decided to stick to the familiar and very popular concept instead. Therefore the main advantages of the new carbon frame are a weight reduction of around 650 g and the significantly sleeker integration and appearance of the bike. Trek has equipped the top tube with a mounting option for a Wolftooth B-RAD system. The system allows you to quickly attach either an inner-tube or a tool to the bike and forget about carrying uncomfortable backpacks on short rides. In typical Trek style all Powerfly models come with a RE:aktiv rear-shock and ABP-link which keeps the suspension fully active even under braking. The geometry can be adjusted between two positions via a flip chip.
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-56-1140x760.jpg)
Revised spec for the Trek Powerfly LT Alu
Even if you won’t buy one of the carbon versions with the Powerfly LT you’ll get quite a few performance upgrades in the coming season. In addition to the battery integration Trek has adapted the spec of the bikes. All Powerfly LT models feature an eBike-specific fork and powerful four-piston brakes. Trek also redesigned the Bontrager Line dropper seat post and used the new SRAM Eagle groupset. Compared to the cheaper Schwalbe Nobby Nic Performance tires the new Bontrager XR4 offer noticeably more grip and puncture protection.

The Trek Powerfly LT 2018 on the Trail
We had the opportunity to test the Powerfly LT 9 at Trek’s launch-event on the gorgeous and varied trails in the Swiss Heidi-Land. Compared to the previous model the handling of the new version has changed very little. The better grip of the new tires might be the most noticeable change on the new version of the Powerfly. Like its predecessor the new Powerfly is a confident climber. The steep seat angle and rather long chainstays will get you at the top of steep climbs without a problem.
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-2-2-1140x760.jpg)
On the downhill the Powerfly feels safe and balanced. It’s not the nimblest bike out there but it’s still very easy to ride. You won’t have to shift your body weight too much to get good grip on both wheels and the bike will always feel pleasantly predictable. But if you’re looking for a very lively super nimble bike the Powerfly might not be able to fully satisfy you. Quick direction changes and narrow sections require a very proactive riding style and quite a lot of strength.
![trek powerfly occasion](https://ebike-mtb.com/wp-content/uploads/sites/2/2018/06/Trek-Powerfly-Carbon-2018-4-2-600x400.jpg)
Our take on the new Trek Powerfly LT
Good stuff made better! Trek didn’t reinvent the wheel but the new Powerfly is a better version of the popular bike with many added improvements. The handling is very similar to the previous version. However you can clearly feel the performance upgrade of the tires. Unfortunately we didn’t get the chance to ride the new carbon version yet but even just the look of it has already convinced us. We’re not sure whether the carbon upgrade is worth the extra money but since our purchasing decisions are often driven by aesthetics and emotions we think that the new Powerfly Carbon will have certainly find many fans.

Price: $5999.00 | Model Year: 2021 | A premium
A premium "do anything" full suspension electric bike that's equipped to handle pavement, trails, light mountain terrain, rain, shine, day, or night conditions. Available in five frame sizes for optimal fit, the XS and S come with 27.5" wheels and the M, L, and XL come with 29" wheels. Sold through one of North America's largest network of dealers. Trek and Bosch provide excellent support and warranty.
Custom made extra-wide plastic fenders are durable and quiet, very capable in off-road conditions. A sleek and sturdy rear rack provides 25kg (55lbs) of cargo capacity with pannier hangers on both sides and a removable top platform for trunk bags. Puncture resistant tires also feature unique black reflective stripes that combine safety with aesthetics.
Downtube-integrated battery pack and mid-drive motor keep weight low and center. Trek designed a "RIB" battery casing includes a handle for safe removal and transport. The battery doesn't rattle, and it can be charged on or off the bike with the fast 4 amp charger. Peformance Line CX motor is the most powerful from Bosch, but lightweight with a magnesium casing.
Highly adjustable air suspension front and rear with 120mm and 100mm travel respectively. Boost hub spacing and thru-axles increase wheel strength. Extra large 203mm hydraulic disc brakes with heat sinks and alloy cores deliver incredible stopping power. The biggest trade-offs here include the high price, smartphone display (that some may not like), louder motor operation, and increased weight (due to the high capacity battery and accessories).
