In this paper, the structure of the bicycles consist twelve parts and three absorbers connected between the parts. The material properties of parts and the related motion and constrained conditions between parts are defined. In the analysis of simulation, the absorber is described by using both the spring coefficient and the damping coefficient. Loads of the bicycle included the weight of driver and reactions are assumed to two periodical vertical force functions and one periodical torque function. Effects of spring coefficient and the damping coefficient of absorbers on the position of center mass of the frame and the twist angle of the rear frame are examined. Effects of frequencies of loads on the position of center mass of the frames and the twist angle of the rear frame are also investigated.
