The Rail 9.9 is our best long-travel electric mountain bike. You get an extra-beefy carbon frame, unbelievably smooth RockShox suspension, super-precise Shimano XTR drivetrain and a powerful Bosch Performance Line CX motor with an extra-long range battery and smart system, plus the new Mini Remote and System Controller display that sits flush with the top tube and pairs with the eBike Flow app to give you activity tracking, navigation and Bluetooth connectivity.
You want to spare no expense on your e-MTB experience. You want the most adjustability, smoothest performance, longest range and most high-tech electric assist you can get. You love customisation and want all the cool features of the Bosch smart system.
An upgraded OCLV Mountain Carbon frame with longer reach and oversized head tube and seat tube for maximum strength. An extra-long-range 750 Wh battery, ultra-adjustable RockShox ZEB Ultimate fork, RockShox Super Deluxe Ultimate Thru Shaft shock and ultra-responsive Shimano XTR 1x12 drivetrain. You get Bosch's smart system Performance Line CX with a new Mini Remote and Bluetooth® System Controller display that's integrated into the top tube.
The Rail 9.9 is all about top-shelf tech. RockShox's best enduro fork, Bosch's biggest battery, the super-refined shifting of XTR, an updated frame and AirWiz pressure monitoring, plus Bosch's latest tech with smart system.
- The new System Controller shows your currently-selected assist level and remaining battery level. It's neatly integrated into the top tube for maximum protection and a sleek look.
- Bosch's new smart system gives you all the same power and responsiveness with a new discrete Mini Remote that's streamlined with just the controls you need at your fingertips to toggle through assist levels or change to walk mode
- TyreWiz and AirWiz let you confirm that your tyres, fork and shock are at the right pressure at a glance. No more getting the pump or gauge out just to check
- Intelligent eMTB and eMTB Lite modes adjust the assist automatically based on your input to give you just the right amount of power for your ride
- The new frame is extra stout with a 34.9 mm seat tube to accommodate more robust dropper posts and an oversized head tube that works with burly e-MTB-optimised forks for less flex and more precise steering
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.
Removable Integrated Battery
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.
Bosch Mini Remote
The compact, ergonomic Mini Remote lets you easily change assist level, activate Walk mode, or turn on optional lights, all without moving your hand off the handlebar. Plus, it's wireless and connects with your System Controller via Bluetooth
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.
RockShox AirWiz and Quarq TireWiz
TyreWiz monitors your tyre pressure while AirWiz monitors your fork and shock pressure. Set your desired pressure in the SRAM AXS app and then just check the lights before each ride - red means you need a pump, green means go and ride.
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.
