Uncompromising E-MTB Performance
Unleash the ultimate e-MTB experience with the Rail 9.9. This machine is engineered to conquer any challenge. The rock-solid carbon frame and top-shelf RockShox suspension handle the toughest trails with ease. SRAM's wireless electronic drivetrain delivers lightning-fast, effortless gear changes. Conquer climbs effortlessly with the powerful Bosch Performance Line CX motor and extra-long range battery, all controlled through the sleek, integrated Mini Remote and System Controller display. Shred trails with confidence and control – the Rail 9.9 is built to push your limits.
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.
*Please note size: small features a 625Wh Powertube battery.
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.
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.
Transition to transmission
The SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner-looking, it's also more precise under load and easier to set up.
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.
Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
