The Walkthrough
favorite_borderWhy you'll love it
OCLV Mountain Carbon main frame with alloy stays make for a bike that's light and trail-tough
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 to remove the battery without tools, and lets you mount a water bottle cage—even on full suspension e-MTBs
Longer travel suspension and 27.5+ mid-fat tires are the perfect combination for traction, stability, and capability on rough 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 rides like a mountain bike because it is one: it has the same frame and suspension tech we've refined in our decades-long trail heritage
"It's nice to have a dropper post, fully-adjustable suspension, and a frame that is well-balanced. The drive system is positioned well and performs incredibly. Trek really dialed in their rear suspension and ABP reduces skipping so the rear wheel track the ground. The removable battery pack with a handle makes this an easy bike to lift, transport, service on the trail, and park securely."
"On terrain that an elite-level XC racer would struggle to conquer, the Powerfly winched up huge mountains with seamless power delivery, especially in eMTB mode that automatically matches your effort. Planted and sure-footed on the descents, it gives you the confidence to release your grip on the powerful brakes and push the tires to the limit."
"The eMTB mode is a fantastic alternative to the manually adjusted power settings found on most other e-bikes. The beauty is that eMTB mode works so well, you can forget about it entirely and focus on the ride instead. Having e-bike specific forks and four piston brakes for example is something that seems obvious, but surprisingly few companies actually make happen."
"Powerfly really feels at home blasting around even the most extreme trails. Rough terrain is simply swallowed up by the capable suspension. The relatively long chain stays are a huge advantage on steep sections, letting you stay seated without losing any traction. The front wheel hardly ever lifts off the ground and the central position makes it easy to pedal on technical sections and maintain your balance."
Bosch's Performance Line CX motor is made specifically for off-road use with more torque and power for better acceleration. The intelligent eMTB mode automatically adjusts the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power. You get optimum control, traction, and battery life so you can focus on enjoying the ride.
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Trek's Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
To see how far you can ride your electric mountain bike on a single charge, check out Bosch’s range calculator. We’ve auto-filled the variables for this bike model and the average rider, but you can make adjustments to get your most accurate estimate.
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. The rim strips are already installed; just add TLR valves and sealant.
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.
This bike has a maximum total weight limit (combined weight of bicycle, rider, and cargo) of 300 pounds (136 kg).

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
