A prostration-type dual-drive bicycle comprises a frame (1), a front wheel (2), a rear wheel (3), a front driving assembly (4), and a rear driving assembly (5). The front wheel (2) and the rear wheel (3) are separately disposed on the front portion and the rear portion of the frame (1). The rear driving assembly (5) comprises a rear wheel transmission mechanism (51) used for driving the rear wheel (3) and a pedaling mechanism (52) used for driving the rear wheel transmission mechanism (51). A knee dynamic support mechanism (53) synchronously moving along with the pedaling mechanism (52) is mounted between the pedaling mechanism (52) and the frame (1). Multi-point dynamic support is used on the prostration-type dual-drive bicycle, so that riding comfortableness and riding efficiency are improved, and the prostrate-type dual-drive bicycle has functions of climbing and fitness. |
