Introduction

Every thrill-seeking rider dreams of an intense ride on rugged, winding trails. So when faced with the rolling hills and mountains, we desperately want a bike that performs well enough to make our dreams come true. Fortunately, the Trek Powerfly 4 is such a cost-effective e-bike with both commuting and off-road performance.

First, the rugged aluminum frame gives the Trek Powerfly 4 a more spacious and lighter body. Second, the high-performance Bosch and high-performance CX (250W, 85Nm) motors help you reach speeds of up to 20 mph. Finally, the Bontrager XR3 is equipped with 29″ wide tires that give you the confidence to maintain strong traction even on gravel-strewn sandy trails.

We have been reviewing the Trek Powerfly 4 for two months, and to make the results more informative for you, we’ll elaborate on the Trek Powerfly 4’s performance while riding, key features, components and specifications, and other versions in the series. If you’d like to learn more about the versions, please refer to our review.

Trek Powerfly 4 General Riding

The versatile Trek Powerfly 4 is a very cost-effective choice. It’s not a vehicle for off-road riders and is a smart choice if you use it for commuting to work.

When I rode the Trek Powerfly 4 for five miles on my commute, it still performed well. The 71.5° seat tube angle is not as steep as previous mountain bikes, instead, it fits my seating position better and gives me a comfortable riding experience.

The 29″  Bontrager XR3 is a natural for the second half of my brick road! Its protruding aramid beads cling to the ground like powerful suction cups, turning fast while maintaining the ultimate in smoothness. Of course, 29″ tires aren’t the only option, as Trek has given the Trek Powerfly 4 more tire options. If you want more responsive steering, then I’m sure the 27.5″ size is the best choice for you.

I didn’t feel my pedaling struggle as much as I used to when passing up the inclined uphill grade of about 5%. I think that’s what I felt most about the Bosch Performance CX, as the torque of 85Nm easily allowed me to overcome the steep climb.

At the same time, with the quick-action Shimano Deore M4100, 1×10-Speed drivetrain, it was easy enough to adjust the speed so that I still had enough energy for an easy ride even in the last kilometer of the sprint. Of course, I wouldn’t mind a 12-Speed gearing for the next version of the Trek Powerfly 4, after all, more and wider speed options would make for a more interesting riding experience.

Trek Powerfly 4 Trail Riding

Of course, as the main battleground of the off-road surface, Trek Powerfly 4 still surprises people with its performance. At the weekend Jack and I went to the famous Stromlo Forest Park to challenge the 40km of mountain trail running.

We were also a bit worried when faced with rocky forest gravel trails and rugged and changing mountain passes. Still, the Trek Powerfly 4 showed no signs of trepidation. To be honest, I was worried that the overly bumpy ride would leave me physically sore and numb, which is something no one wants to endure. But apparently, the SR Suntour XCM 34 fork does this very well, with 120mm of travel to offset more of the impact. Also, the quality VP Components, VP-536 Nylon Pedal didn’t put too much drag on my ride, and there’s nothing like that to get the ride off to a great start.

When I rode onto wet and muddy grass trails, I was concerned that going too fast would introduce a certain amount of instability. But apparently, the Trek Powerfly 4 took this into account early on. the Purion controller features a walk assist and an intelligent eMTB mode that automatically delivers the right amount of power for my terrain. This allows me to always ride at a smooth speed.

Of course, it’s worth mentioning the amazing gear shifting of the Shimano Deore M4100’s 10-Speed drivetrain. When I made an ascending sprint, the gear selection was made almost instantly. I gained a faster ride by locking into the SR Suntour XCM 34, putting me well ahead of Jack.

Not only that, the Tektro HD-M275 Hydraulic Brake was still able to perform strong and stable emergency braking in the face of slippery muddy roads. This, combined with the rough tread of the Bontrager XR3’s prominent surface, provided enough safety and confidence for my ride.

Main Features

You may not imagine that Jack exclaimed “Wow, unbelievable!” when he first saw the wild Trek Powerfly 4, whose unparalleled bodywork conquered everyone in the audience.

First and foremost, the rugged and refined alpha aluminum alloy brings great ductility to the Trek Powerfly 4. Through continuous cold extrusion and butting at multiple points, it is hydraulically formed into complex tubes to achieve a strong surface and minimal body weight.

Secondly, the internal cable setup not only keeps the cables in a safe location but also allows you to reduce maintenance. This also gives the Trek Powerfly 4 a longer life while reducing your cleanup and maintenance costs. You don’t have to worry about damage to the motor from off-road bumps. Finally, the unique motor is strong and durable, keeping the material light while providing you with the safest protection for your ride.

Of course, you can also choose whether you want to install fenders and rear brackets according to your wishes.

No matter what type of bike you’re on, scientifically thoughtful geometry always leads to a more comfortable and efficient ride, and the Trek Powerfly 4 is no exception.

The 71.5° seat tube angle isn’t a steep presence, and it’s better suited for novices to conquer those not-so-steep uphill surfaces. At the same time, the Trek Powerfly 4 is set up with a shorter and smaller wheelbase length to offset the unresponsiveness of the big and wide Bontrager XR3 in terms of steering. The benefit of this is also that you can maintain a smooth turn even in the face of those thrilling roads with sharp turns.

One more thing, the not-so-steep head tube angle (65.0°) has a crucial impact on your short-track descents. At the same time, the 11.4mm trail provides you with a good riding experience, and you can ride freely on winding roads.

That’s right, comfortable and snug geometry will always support your ride in every way.

Components and Specifications

Shimano deore m4100, 10-speed drivetrain.

The Shimano Deore M4100, 10-Speed drivetrain has absolute performance, and you only need to flick the right-hand tab for a butter-smooth shift.

The crank technology of FSA Bosch CK-220 enables you to accelerate easily even on some ascending sections with about 5% grade. And it allows you to shift effectively in the face of different riding situations. So you have to admit that Shimano is one of the best drivetrain manufacturers.

But as I mentioned above, I believe the Trek Powerfly 4 would have sold better if the 10-Speed drivetrain had been replaced with a 12-Speed operating system.

Bontrager XR3 Tires

The Bontrager XR3 gave me the answer as to what kind of tire can handle the gravel and dead branch spreading single-track trails. The 29”x2.6” tire size is extremely stable, and its prominent tread pattern gives me a smooth ride even when you’re dealing with wet and flat mossy roads. Also as a regular XC racer, the Bontrager XR3 can increase traction and comfort while reducing pressure when riding on off-road tracks. What’s more, the special anti-puncture system eliminates the risk of flat tires, eliminating your worries. Of course, Trek also offers a 30-day unconditional refund, so if you’re not satisfied with it, you can visit your local store for an exchange or refund.

Tektro HD-M275 Hydraulic Brake

Can you live with a bike that doesn’t have enough braking power? I can tell you without hesitation that I would say “No” to such brakes. Without a good brake, your ride will be a huge safety hazard. But the Tektro HD-M275 Hydraulic Brake doesn’t give you that concern.

In addition, the open system makes it easier to clean and maintain, while the dual-piston braking device has plenty of confidence in braking. At the same time, to eliminate the noise caused by brake friction, Trek has thoughtfully applied low-noise resin pads on the bottom for a better riding experience.

SR Suntour XCM 34 Fork

I believe the SR Suntour XCM 34 fork is the result of Trek’s careful consideration. The fork suspension it comes with is very resilient and will not be damaged by overly bumpy roads. And yes, it’s sturdy. After two months of riding on gravel and sand, it still performed as well as new.

One might complain that 120mm of travel for mountain trail riding would not have an impact on the performance of the shock. The fact is it performs very well. The streamlined, superior structural configuration works by retracting up and down to counteract the feeling of more vibration as it moves forward. Give it a try, I’m sure even veteran XC race riders will rave about the SR Suntour XCM 34 fork.

Bosch PowerTube 500Wh Battery and Motor

As we all know, in an electric vehicle, the motor is the soul. the PowerTube 500 stands out with its black, high-grade anodized aluminum finish. In addition, the Bosch high-performance CX motor sets the standard for eMTB performance. Meanwhile, torque is up to 85Nm, and the intelligent eMTB mode fuels body-extending performance that automatically adjusts to the terrain. What’s more, the RIB as an all-in-one battery has a built-in handle design that can be easily removed and reinstalled in the frame without tools. After our measurement, it can provide a maximum speed of 20mph, which is the most powerful assistant in your race.

Other versions of Trek Powerfly

To give you more options, we tested the other Trek Powerfly 4 models in an objective and unbiased manner, including the Trek Powerfly 5 for a certain amount of time.

Also made of alpha aluminum alloy, Trek Powerfly 5 has a much lighter body condition. This is certainly good news for those who seek a lighter body.

The Trek Powerfly 5 is a higher-end RockShox Recon Silver RL, but with the same 120mm travel, it has a better damping experience.

Meanwhile, the Shimano XT M8100 1×12-Speed drivetrain makes up for the regret I had with the Trek Powerfly 4. Because it has a more lush gear ratio and a wider range of speed adjustments, it provides a more interesting riding experience.

If you’re like me and have an inexplicable obsession and love for 12-Speed drivetrains, then I think the Trek Powerfly 5 will fit the bill. But it also means you’ll have to spend more $$$, which may be a bit of a hit to your wallet.

Comparison Table

Trek powerfly 4 vs bulls aminga eva 2 27.5” diamond.

Bulls Aminga and Trek Powerfly 4 are also used as electric bikes, both of them are made of Alfa aluminum, which makes the body strong and tough enough.

But the difference is that Bulls Aminga pays more attention to the ride on bumpy roads, as it also pays extra attention to the choice of a fork. The Suntour XCR 32 Air is made of higher-quality materials and is lighter in weight. Even in the face of rolling hills and forests, it can mitigate damage to the rider’s body through high-speed movement.

However, it should also be noted that the Trek Powerfly 4 has more options in terms of tires (27.5”/29”). The Bulls Aminga is a bit inferior at this point, with only 27.5″ tires available. This is not good news for riders who are used to big tires all year round.

If you have a preference for larger tires, then I believe the Trek Powerfly 4 is still the best choice for you.

Trek Powerfly 4 vs Scott Aspect eRIDE 920

With the same weight (both measured at 23.4kg), the Scott Aspect eRIDE 920 brings the 12-Speed system I mentioned. The choice of Groupset is also based on the higher quality NX Eagle, SX Eagle, and a wide range of speed control systems to provide a more interesting riding experience.

Not only that, the PowerTube has a more advanced battery option, with 625wh of battery power to provide a longer, faster ride. But unfortunately, the Scott Aspect eRIDE 920 still doesn’t have the same freedom to choose the tire size as the Trek Powerfly 4. This is again similar to the Bulls Aminga we mentioned above.

In addition, if you don’t like your battery exposed, the Trek Powerfly 4 may appeal to you. This Trek Powerfly 4 not only protects with the battery completely hidden in the frame but it can also be easily removed.

Notably, it comes with Purion controller with a walk assist and intelligent eMTB mode that automatically delivers the right amount of power for your terrain.

I have to say that Trek Powerfly 4 has a great price/performance ratio, both in price and in performance configuration, and is a good choice.

Trek Powerfly 4 VS Rocky Mountain Growler Powerplay 30

The Rocky Mountain Growler Powerplay 30 is, in my opinion, a swift bull. It can brave the endless gravel land. In addition, the 634wh fully integrated lithium-electric battery gives it the ability to go crazy in XC races. In this respect, the Trek Powerfly 4’s 500wh battery may be a bit inferior.

Also, the Suntour XCR 34 fork has a slightly longer travel of 130mm than the Trek Powerfly 4. This also provides more cushioning to eliminate most of the ground vibrations. It also has a dropper design on the bottom saddle, which is a big competitive advantage for an e-bike of its type. The double protection can give you the ultimate riding experience.

The Trek Powerfly 4’s removable battery, however, is a highlight for many riders who prefer a clean charge. And the Trek Powerfly 4’s fork with a locking feature also prevents you from losing kinetic energy while riding on flat roads due to the work of the shock and thus slowing down your speed.

If you’re aiming for gravel-strewn forest roads with rugged rock walls, the Rocky Mountain Growler Powerplay 30 may give you the courage to sprint. But if you’re on a budget or want a simple, comfortable ride, I’d recommend the Trek Powerfly 4.

Trek Powerfly 4 vs Giant Stance E+ 2

The Giant Stance E+ 2 is the top end of the Giant line with unmatched advantages. It has a sturdy body as well as a strong surface, which is hydraulically formed into an exclusive tube body through a specific technology to achieve the perfect combination of weight and body. Unlike the hardtail vehicles of the Trek Powerfly 4, the full-suspension Giant Stance E+ 2 offers the ultimate damping experience with its front and rear travel (130mm front and 120mm rear). But if there’s anything that one laments, it would be the 500-watt-hour battery. It is very heavy and makes a lot of noise when it is started. If you’re looking for a full-suspension off-road e-bike, then the Giant Stance E+ 2 is the bike for you.

Although the Trek Powerfly 4 only has a dampened fork, this may not be as good as the Giant Stance E+ 2 when facing relatively harsh and bumpy terrain. But I think that’s forgivable – after all, the Trek Powerfly 4 doesn’t have a rear shock. And in real-world climbing, the Trek Powerfly 4 performs better. The relatively lighter body also saves weight on upward climbs.

If you prefer more challenging upward climbing routes, or if you prefer the more expensive Giant Stance E+ 2, the Trek Powerfly 4 is a great choice for the price.

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

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.

One bike for all occasions – with the Trek Powerfly FS 7, the American brand promises to have created a true all-rounder. The smart concept should please everyone from trekking and leisure riders to moderate trail adventurers. We tested the 120/100 mm travel eMTB with the Bosch Performance Line CX motor to find out whether the new Trek Powerfly FS 7 is the all-rounder that many have been looking for.

All-round capabilities

Overall concept

Good-natured and intuitive handling

Confidence-inspiring

Comfortable riding position and low top tube

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).

The 2021 Trek Powerfly full suspension e-MTBs blend European sensibility with modern trail capability for a unique e-mountain bike option.

If I had to think of one common theme that continually came up during our time with the Powerfly, that would be it—too damn fun. Over the months we’ve had this bike, we’ve done it all and it does it all with ease.

Oct 2018 · Alan Muldoon

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.

Built on the bones of the legendary Fuel series, the Trek Powerfly 7 FS is the top-of-the-line e-bike for Trek in Australia. It's got great pedigree, but we didn't love every aspect of its performance

Top notch build quality.

Frame feels indestructible.

Great rear suspension.

Torquey motor with plenty of range.

Will climb anything you point it at.

RockShox Recon fork isn't up to scratch.

Long rear end makes for sedate feel.

The Trek line of e-bikes continuous to evolve with better integration and better components for the mountain bike experience. - Mtbr.com

Jun 2017 · Oli Woodman

An exceptionally capable package which will take you further and faster without the need for a lift pass. Buy if you’d like to scale climbs almost as quickly as descents and aren’t afraid to be a little different

Long wheelbase makes for almost absurd stability, superb mechanical grip from well-matched and supportive suspension, Drivetrain and motor play very well together, components list features plenty of excellent e-bike specific parts

Flimsy tyres are at odds with the rest of the bike, New ‘e-mtb’ power mode perhaps a little too keen for some

Trek Powerfly 4 Review

Dano from our Colchester Revolution Store recently had a chance to get hands-on with the Trek Powerfly 4 . He let us have his initial thoughts, we wanted to share them with you: 

lets you travel to destinations that you never thought you’d reach on a mountain bike.

“ First thoughts are this is a stunning looking bike. My colour of choice would be bright orange, although it is a close run with grey and black.  625 or 500 Watt battery with some of the colours, again choices…  Plenty of attention to detail, quality finish, through axle, etc. Love the way the battery sits in the frame. Very neat.  The ride is smooth, with the power just flowing in from the CX Bosch motor. I forgot it was an Ebike during the ride. Just enjoyed the experience.  The bike is ready to go, but mudguards, the rack can be easily fitted and a wiring loom is ready if lights are required.  Spec is great, but plenty of options to upgrade if you like to make it personal.  Enjoy ” 

The Technical Bit

  The Trek Powerfly 4 is an affordable electric mountain bike. This e-MTB is built with parts that hold up, like a dependable 9-speed Shimano drivetrain, a 100 mm suspension fork, fast-rolling wheels, and a Bosch Performance CX motor that assists up to 15.5 mph. This bike expands your boundaries and lets you travel to destinations that you never thought you’d reach on a mountain bike. 

• Trek’s Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage 
• This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation and having a ridiculously fun time on the trails 
• The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain 
• It’s equipped with an external charging port for easy charging on or off the bike 

Why do you need daytime running lights?

Powerfly 4 is our most affordable electric mountain bike

It's built with parts that hold up, like a smooth-shifting Shimano drive train, and a powerful Bosch motor. Plus, it features our user-friendly Removable Integrated Battery (RIB) system that's fully encased in the frame yet doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations that you never thought you'd reach on a mountain bike.

It's right for you if...

You're sold on the e-bike revolution and want the capability and versatility of a mountain bike at a price that doesn't resemble the car you're trying to use less. You want bigger, better off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.

The tech you get

A tough yet refined aluminium frame that fully encases a 500 Wh battery for sleek looks. The latest from Bosch with smart system Performance Line CX motor capable of speeds up to 20 mph (25 km/h in Europe), including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app. A 1x10 Shimano drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

Why you'll love it

• Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
• The top-notch new Bosch smart system gives you more control over your ride with navigation and activity tracking through the eBike Flow app
• It comes equipped with Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
• It's equipped with an external charging port for easy charging on or off the bike
• You can boost your Powerfly’s utility by adding a rack and mudguards, plus built-in wiring lets you easily install lights powered by the motor

The final word

Our most affordable electric mountain bike comes with the same powerful Bosch motor and intuitive controller as our most expensive e-bikes, with a smaller battery and parts chosen to give you great value.

Trek Powerfly 4 Electric Bike on Exmoor - A review by Ross

Thinking of buying an electric bike find out how one of our new forest based electric hire bikes coped with the rigours of a somewhat hillier, wetter and more rugged national park.

At Cyclexperience, we get customers with an ever-increasing interest in renting or buying electric bikes and the main question area is usually range related.

It’s a difficult question to answer since it depends on many factors (assistance levels, battery size, weight, weather, terrain, rider ability etc) so I decided to head west and take an electric bike to Exmoor for the day. I plotted a 20-mile route which started near the head of the River Exe and included a fair amount of steep climbs.

The Bosch CX motor has 4 levels of assistance and I decided to test E-MTB mode which modulates power between 120% and 300% depending on the pedalling dynamics. I was impressed from the start.

Traversing bogs on an uphill slope, I still managed to keep up with a herd of startled deer in the distance before a flooded ditch slowed things down but the motor maintained the right amount of traction to the back wheel and kept things stable, moving forward smoothly.

It wasn’t long before I was over the hill and following the bridleway along with firmer but now rockier terrain. Being the base model Powerfly, the forks were basic Suntour with lockout and an element of damping. However, the 100mm travel was sufficient and the thicker stanchions coped well with the rocky path, especially since my airborne skills are less than ambitious.

I was now speeding along with a massive smile and enjoying the rare sunny winter weather and beautiful Exmoor scenery.

I had just passed the ruin of Hoar Oak Cottage when disaster struck on a hill in the form of a snapped chain! I wasn’t changing gear nor pushing that hard on the crank when the snap link came apart, losing one side in the mud!

I had adjusted gear cable stretch on the fly earlier when the gears jumped but obviously not enough! E-Bike riding does disguise the actual torque being delivered through the cranks so care is needed when changing gears quickly (especially up muddy hills!).

Having not brought another snap link and remembering my trusty Topeak tool still sitting in the back of the van, I was now considering my limited options, stashing the bike and jogging 5 miles back being the main one! Luckily buried in the depths of my rucksack was an old Giant multitool so I was soon on my way again, one link shorter, and with gears adjusted I had no more chain issues for the rest of the ride.

The next 8 miles were outstanding fun with steep descents and river crossings followed by challenging climbs which the Trek Powerfly managed with such ease! I couldn’t remember when cycling was this much fun.

I enjoy road and gravel biking and the gamification of Zwift on the turbo trainer and while that keeps my fitness in check, this was a new off-road biking experience that I felt anyone could enjoy with a bit of basic skill training.

I was getting so carried away that I hadn’t spotted that I was down to two bars on the charge indicator. With only 7 miles to go, I wasn’t that worried but I selected Eco mode when it was flat and turned it off on a flat road section but even then the unpowered contrast felt like I had two flat tyres and gained 30lbs!

People do comment about how heavy Electric Bikes are but you probably wouldn’t even think about how heavy a motorbike is until you run out of petrol!

It's the same principle for electric bikes (until you try and hang it off the back of a motorhome but checkout Thule for a bike rack with a ramp). Sure, there are lighter carbon electric bikes on the market now but they do come with an appropriate price tag and still have 5kg worth of motor and battery to cart around!

As the winter sun started getting particularly low, I noticed the battery was now at 1 bar and I still had 2 hills to climb, one particularly lengthy. But making the most of the descents (oh for regenerative charging) plus a short push across a boggy field, I got to the village of Challacombe and then had to decide whether to take the (less hilly but still hilly) road back or continue the final 2 miles off-road as planned.

Without lights, I opted for the off-road choice and the battery inevitably yet quietly ceased to assist at 18 miles. While able to ride (just) on the flatter parts of the track, when the hill kicked in and the mud got deeper, it became much quicker to get off and push.

And so ended the final part of my journey apart from a final downhill section back to my Van.

There was a moment of regret while dragging the bike up and over the hill but the overriding memories were being able to enjoy the flow of the descents knowing that the soon-to-follow climb was probably going to be even more enjoyable! The ability to carve through mud and bogs was an added extra bonus.

I’m sure some people will complain that E-MTB’s will unleash an unprecedented surge of cyclists onto our green and pleasant lands. I doubt this since not everyone wants to venture miles off the beaten track getting wet and muddy just to experience the ease of uphill cycling.

It’s a very niche hobby in the grand scheme of things and as long as the public Rights of Way are well signposted, there is no need to venture from the excellent trails this country offers whether on horseback or bike saddle.

I was surprised at the sub-20-mile range I achieved on this test ride as some customers manage 30+ miles on our hire bikes in the New Forest. I also tested one of our Giant Fathom E-bikes in the Brecon Beacons earlier in the year which lasted a similar number of miles but with a 400wh not a 500wh battery like the Powerfly 4.

It could have been the scale of the climbing combined with the saturated ground or perhaps the bike only had its factory charge as it was brasnd new. It seems I may have to go back to Exmoor to conduct more scientific research!

Book one of our bikes if you want to try an e-bike in the New Forest or take further afield and do some of your own research!
