Why you'll love it:
- It comes equipped with fenders, a rear trunk rack, and lights that are powered by the battery so you're ready to ride right from the start
- Download the COBI.Bike app and your phone becomes an on-board computer. Attach it to SmartphoneHub to charge, make or take calls, listen to music, get turn-by-turn directions, and more
- Wide Line Comp 30 wheels provide more tire support so you get better traction and control
- 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
- The size S frame features a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits-29" wheels on larger frames, 27.5" wheels on smaller frames
Wheel size:
- Sizes X-Small – Small: 27.5-inch
