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.
