The ride, not just the specs
Rail is an electric mountain bike for riders who want more: more laps, more climbing, and more time on the fun parts of the trail.
The motor helps you up so you have plenty left for the way down.
What makes it special
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
