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 an e-MTB with the latest user-friendly tech is the best way to get them.
The tech you get
A tough yet refined aluminum frame that fully encases a long-range 500Wh battery for sleek looks, a Bosch Performance CX (250W, 75Nm) motor that assists up to 20 mph or 32 km/h, a Bosch Purion controller, 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.
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.
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
- This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation, and 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
- You can boost your Powerfly’s utility by adding a rack and fenders, plus built-in wiring lets you easily install lights powered by the motor
