The Walkthrough

favorite_borderWhy you'll love it

  1. OCLV Mountain Carbon main frame with alloy stays make for a bike that's light and trail-tough
  2. 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
  3. Longer travel suspension and 27.5+ mid-fat tires are the perfect combination for traction, stability, and capability on rough trails
  4. The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
  5. 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

Removable Integrated Battery

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.

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.
