The bottleneck-breaking high speed inverter motor sustains high-torque output with the strong power generated by the vector magnetic field with sine wave, thus more energy-efficiency, longer range, and smoother acceleration.
R1 uses a combination of battery and seat, which not only increases the available space of the bicycle, but also increases the beauty. Moreover, the battery is very powerful and its endurance is very strong.
