Box One-E 9S Drivetrain


We developed the Box One-E system as an e-bike specific drivetrain to offer a better riding experience. 9 speeds and wide range gearing means less shifting action and more efficiency for the motor. With the 42 and 50 tooth low gears, it’s possible to maintain optimum pedaling cadence while climbing steep hills. By enabling riders a higher pedaling cadence, the electric assist feature can be fully realized.
