It comes equipped with a Bosch Performance CX drive system with full power for crushing laps and big climbs while its massive battery takes you the distance. 160 mm of front and rear travel make Rail+ super capable in the rough and rowdy, and adjustable geometry lets you customise it for how and where you ride.
You want a bike that maximises the fun and is up for gnarly rides that get you off the grid or just hammering in an extra lap or two. You need the capability of an enduro bike for pointing it down the rough and rowdy, and love the feeling of full assist taking the sweat out of the climb back to the top for more

The Rail + 8 is an enduro e-MTB dialled for big adventures. It packs in capable, adjustable geometry, a massive battery and a powerful motor to get you wherever you want to go. An upgraded drivetrain balances price and performance for a ride that's ready for anything.
- The Rail+ delivers adventure with plenty of travel and power for getting after epic rides that take you peak to peak or chasing endless enduro laps
- The powerful Bosch Performance CX system goes full gas up steep climbs and keeps you cool for the descents
- You can tweak your geometry and suspension leverage rate for how you ride, and add in adjustable angle headset cups (sold separately) for even more adjustability
- The massive 800 Wh RIB 2.0 battery supports you for big miles and can be easily removed for travel or storage
- It's compatible with the Bosch PowerMore booster battery for going even further on epic adventures
Bosch Performance Line CX motor
The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
New RIB 2.0
Removable Integrated Battery (RIB 2.0) makes it easy to remove your battery for more convenient charging or travelling, and you don't have to worry about dropping it thanks to a secondary safety catch.
Mixed wheel size
You get a 29"" front wheel for monster truckin' over stuff, with a smaller 27.5"" wheel out back for getting rowdy.
Adjust the suss for full send
Adjust the leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don't want to bottom-out, or when you want to run a coil shock.
Bosch System Controller
The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. It's integrated into the top tube so it's out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.
Active Braking Pivot
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.
