A better battery interface

Trek’s exclusive Removable Integrated Battery (RIB) system is the most user-friendly system available. It keeps your battery hidden and protected in the frame, and requires no tools for removal.

Reliable power in every bike

Bosch drive systems are renowned for their reliability, power and ease of use. These systems deliver a powerful, intuitive experience on the trail so you can focus on enjoying your ride. Plus, Bosch offers global support and service that can’t be matched!

Simple. Fun.

With e-MTB and e-MTB Lite modes, you can set your assist level and forget it. You’ll feel it kick in with your chosen level of assist on loose, steep terrain and ease off when you don’t need it.

Whether you’re riding a rugged morning commute or planning an overnighter, you can equip all Powerfly models with accessories that are right for the way you ride, including racks, fenders, lights and a kickstand.
