After the formation of the shock absorber frame tube, it has better strength and a variety of variable shapes, and can improve the connection with the shock absorber. Sex. [Prior Art] Bicycles have the advantages of being relatively inexpensive, non-polluting, non-energy-consuming and health-promoting, so the developing countries will be the main transportation workers of people's daily life. In advanced countries, in addition to some of the mobility functions, they can also cater to them. Environmental protection requirements, and the trend of sports and leisure, compared with cars, bicycles are easy to learn, park and place, occupying a small space on the ground, will not emit greenhouse gases and carcinogens that damage the global environment, and cause accidents of others. The rate is very small, it can cope with many difficult mountains, and it is enough to meet the needs of ordinary people's recreation, sports and transportation. The bicycle mainly uses a simple frame as the connection of the various parts, the transmission of the force and the weight of the supporter. Therefore, the strength and rigidity are the main requirements of the frame. The high strength can avoid the breakage of the ride. & safety concerns, good rigidity can have better power conductivity; in addition, the frame stomach needs to be lighter, which is more labor-saving and faster when riding. The rear shock absorber frame tube is part of the bicycle frame and is usually located under the seat tube. It is mainly used to strengthen and stabilize the joint seat tube, the front and rear fork tubes, and at the same time achieve the transmission of strength; The shock system is used as a buffer
