Rail 9.9 CXR Gen 4

Buy to order bike.
The Rail 9.9 CXR is a race-ready long-travel e-bike that's ready to accelerate to the full right off the the starting line. It features our best carbon frame, smooth RockShox suspension and top-tier Shimano XTR drivetrain. But the real show stealer on this powerhouse is the limited-edition Bosch Performance Line CXR motor that accelerates faster and offers sustained power for ripping through rock gardens without pedalling. It's equipped 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.
