ABSTRACT:
A shock absorber, the shock-absorbing function of which can be turned on/off during movement and includes a basement, a clutch assembly, a control assembly and a shock-absorbing spring, the shock-absorbing spring provides damper elastic force for the respective components of the shock absorber. The shock-absorbing function can be turned off when riding up a slope, so as to prevent the drag force being increased by the up and down motion of the shock absorber. The shock-absorbing function can be turned on when riding on a horizontal road, and it can be turned off again when riding down a slope, so as to prevent the increase of the front tilt angle of the bike and leading to turnover.
