The disadvantage is that the power is flexible, and the power loss is large. It is mostly used for scooters, but also rarely used for riding bicycles. ；Chain drive is used in most riding motorcycle. The advantage is that the power loss is small, but the disadvantage is that the maintenance is troublesome, the chain will be elongated, and the chain must be tightened every 1000 to 2000 kilometers, and it must be oiled.Shaft drive is mostly used for three-wheeled motorcycles, and some two-wheeled streetcars use shaft drive. The advantage is that it is almost maintenance-free, and the transmission direction can be changed . The disadvantage is due to the rotation direction of the transmission shaft and the forward direction of the car Inconsistent, high-speed driving may cause the body to be unstable, so motorcycles with a speed of 250+ mostly use chain transmission, and only street motorcycles that pursue comfort and not much speed use shaft transmission.
