Plus, 130mm front and rear travel with a RockShox Recon RL fork, Tubeless Ready Bontrager Kovee 23 rims, and a 10-speed Shimano Deore drivetrain.

The final word

This bike pairs electric-assist performance with singletrack trail capability. It's a fun, forgiving, full suspension ride that can help you reach new destinations on rugged trails with pedal-assist of up to 20 mph.

The Walkthrough

favorite_borderWhy you'll love it

  1. 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
  2. For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist system to its full potential
  3. 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

"Trek electric bikes are some of my favorites"

"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."

"An absolute riot"

"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."

"Easily one of our top choices"

"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."

"Trek has created something special"

"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."

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.
