WHY YOU'LL LOVE IT
- Rail Gen 3 is built for big adventures, with Bosch's smart system that packs in all the power you need, and a Bluetooth-connected LED remote that's sleek and intuitive
- 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
- Rail keeps your cockpit tidy by skipping a display, but smart system makes it easy to add one
- The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
- Made with the same hard-charging frame tech as our amazing trail bikes, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)
