Specially Constructed Electric Bicycles

A small number of electric vehicles are driven by non-hub motors. These electric vehicles use side-mounted or columnar motors, mid-mounted motors, and friction tire motors. Generally, the electric vehicle driven by this kind of motor will reduce the weight of the whole vehicle, and the efficiency of the motor is lower than that of the hub type. In the case of the same battery energy, the mileage of the vehicle using these motors is generally 5%-10% shorter than that of the hub-type vehicle.
