The invention discloses a bicycle swing rod driving mechanism which comprises a pair of pedals, a driving swing rod, a driving shaft, a follow-up swing rod, a support, a first bevel gear, a second bevel gear, a third bevel gear and a chain wheel, and the left pedal and the right pedal are driven to swing up and down to drive the driving swing rod to swing and the driving shaft to rotate clockwise and anticlockwise. The first bevel gear and the second bevel gear are driven by a one-way clutch to rotate, the third bevel gear is alternately driven by the first bevel gear and the second bevel gear to rotate, the chain wheel is driven by the third bevel gear to rotate together, and then the chain wheel drives a chain, a flywheel and a rear wheel of the bicycle to rotate. In addition, through a quadrilateral connecting rod mechanism arranged in the swing rod driving mechanism of the bicycle, the pedal surfaces of the pedals are always in a horizontal state in the swing process. The bicycle has the advantages of being high in transmission efficiency and easy to operate, and is suitable for sitting riding, standing riding or sitting and standing alternate riding.
