The invention discloses a bicycle bidirectional drive transmission system which is composed of a crank throw, pedals, a wheel disc, a chain or one-way synchronous belt, a flywheel, a chain box or belt box and the like. Mainly, the flywheel, a support, two auxiliary wheels, a steering wheel and a short chain or short single-sided synchronous belt are added to a bicycle rear wheel, and an existing single-sided synchronous belt is changed into a double-sided synchronous belt. A bicycle can be driven to advance when a user steps on the pedals forwards and backwards and can also be driven when the user stands up to step on the pedals up and down by two feet in a multi-position mode, and the pedals do not follow up the feet if the feet have a rest. Full-chain transmission is achieved, no gears are needed, high adaptability is achieved just like an ordinary bicycle, the structure is simple, standards of the prior art are adopted, manufacturing is easy, and maintenance is convenient. The bicycle bidirectional drive transmission system can be used for a single-speed bicycle, an automatic speed-change bicycle, a tricycle, a body-building bicycle and the like and is a latest tool for riding instead of walk and for body building.
