The invention discloses a damping saddle of a bicycle, and relating to the technical field of saddles. According to the technical scheme, the saddle is characterized by comprising a saddle body and afixed beam, two connecting plates are fixed to the face, facing the fixed beam, of the saddle body, the connecting plates are bent into arcs in the width direction of the saddle body, damping spaces are formed between the connecting plates and the saddle body, and the ends, deviating from the saddle body, of the connecting plates are fixed to the fixed beam. An elastic cushion is arranged in the damping space, and the two back faces of the elastic cushion abut against the saddle body and the connecting plate respectively. The shock absorption performance of the saddle is good, and the riding comfort is high. By arranging the arc-shaped connecting plate, the shock absorption effect of the saddle is obviously superior to that of a saddle with a single shock absorption pad for shock absorption. Compared with a saddle using a spring for shock absorption, the saddle has the advantages that the weight and the complexity are greatly reduced, the attractive degree is high, and the saddle is convenient to assemble.
