Why you'll love it
- The Carbon Rail Gen 4 has the same enduro-inspired geometry and huge battery as the previous generation, but now it has a pocket in the top tube that makes Gen 4 compatible with Bosch’s integrated System Controller and Mini Remote
- Its clean cockpit is minimalist and sleek, and the smart system makes it easy to add a display if you want more data
- Intelligent eMTB and Tour+ modes automatically adjust the assist based on your input to give you just the right amount of power for your ride
- SRAM's direct-mount T-Type wireless transmission delivers next-level performance with precise shifts under load and unmatched durability
- 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 remove the battery without tools and lets you mount a water bottle cage
