R900 is an integrated electronic 3-speed gear hub
motor system, with transmission and motor in ONE unit.
Unlike mechanical systems, the R900’s electronic shifting responds instantly, delivering intuitive, natural gear changes with smooth transitions. Seamless 0.2s shifts ensure uninterrupted power during climbs/acceleration. Electronic precision, no lag, no missed shifts.
Its intelligent algorithm enables auto adaptive shifting based on speed, torque, cadence and gradient. Customizable shifting logic via CANbus for different bike styles.
Precise engineering combining motor and automatic shifting in one unit boosts efficiency and reduces maintenance. Optimized layout for flexible bike design.
