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. OCLV Mountain Carbon main frame with alloy stays make for a bike that's light and trail-tough, Longer travel suspension and 27.5+ mid-fat tires are the perfect combination for traction, stability, and capability on rough trails
  3. Advanced spec including e-MTB-specific parts and Trek's RE:aktiv damper take this model to the next level
  4. 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

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.
