The invention discloses a novel driving device of a bicycle. The bicycle mainly comprises a bicycle frame (1), a gearbox (13), a driving rear wheel (11), an overrun clutch (37) and the driving device mounted on the bicycle frame (1) and the gearbox (13). The driving device is characterized by mainly comprising pedals (2), pedal driving arms (4) and pedal balance reset tension springs (6). According to the invention, a pedal driving device driving system is independently arranged, so that the defects that a driving connecting rod of a bicycle with the Chinese patent number of 201420590209.3 in the prior art adopts a single-side single-bar structure and is unilaterally stressed when being pulled to cause non-uniformity of overrun clutch stress, high possibility of breakage and low durability and the like are overcome; therefore, the novel driving device of the bicycle is uniform in overrun clutch stress, quite durable, and quite convenient and stable to tread, and cannot be broken.
