All Mountain E-Bike

Why We Love It
The Powerfly FS is Trek's full suspension all-mountain e-bike. The full suspension version of the Powerfly puts 130mm of rear travel in the frame to make this e-bike capable of riding any trail you throw it at. Take advantage of the Bosch Performance Line CX motor that delivers a smooth and intuitive pedal assist while you mountain goat your way up steep technical climbs then be amazed as the motor gets out of the way and lets you cruise down techy lines with style.
