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
