Since the motor drives the wheel directly, they provide efficient power transfer. Rear hub motors are known for providing consistent and reliable performance. The left-side cable outlet prevents the cable from being snapped if your e-bike accidentally tips over. It also enhances the overall balance of the bike since the rider's weight is more evenly distributed over the rear motor.Compared with the 250w CZJB 90 series motor, the 105C series has better power.
