Suspension is usually made up of two parts: springs and dampers
The spring is the main part of the suspension. This spring is like the usual way we use a spring in a ballpoint pen, but it's much bigger. The spring absorbs the impact force of the ground through the elastic part, and ensures the contact between the tire and the ground. The damper is a device for controlling the tightness and resilience of the spring.
A damper is like a cylinder filled with oil. The speed of moving up and down of the air pump depends on the size of the through hole and the viscosity of the oil. All the cars have springs and dampers, the springs are hidden on the forks, and the shock absorbers are exposed to the outside.
The suspension on the front and rear wheels is separate, and the response can be made according to the condition of the road and the way of riding.
