Technical solution of the present utility model is: this swing type foot-driven lever bicycle includes frame assembly, rear wheel assembly and front wheel assembly, front wheel assembly premenstrual fork support is arranged on the front end of frame assembly, front apron is installed on front forked bracket, driver's handle, car on the handle installs small bell, front brake is installed on front apron, rear wheel assembly is arranged on the rear end of frame assembly, backboard and rear braking are installed on rear wheel assembly, through seat axle, seat cushion is installed at the middle part of frame assembly, it is characterized in that: install at the middle part of frame assembly and swing treadle reverser, the both sides of swing treadle reverser are symmetrical is respectively mounted left sprocket drives, left treadle assembly, right sprocket drives and right treadle assembly, left sprocket drives is identical with right sprocket drives structure, left treadle assembly is identical with right treadle assembly structure；Described swings power transmission shaft, transition axis, sprocket wheel and the transition gear that treadle reverser includes being arranged in casing and case lid, power transmission shaft and transition axis are in bearing is arranged on casing, one transition gear and a transition sprocket wheel are installed on transition axis, left threading axle and right threading axle are respectively in bearing is arranged on casing, it is respectively mounted sprocket wheel, sprocket engagement transition gear on left threading axle in casing and right threading axle；Described sprocket drives includes that big sprocket wheel, chain and minor sprocket, big sprocket wheel are arranged on pedal spindle, and minor sprocket is arranged on rear wheel assembly, connects with chain between big sprocket wheel and minor sprocket.
The utility model has the advantages that:
1, swing treadle reverser is used, gear engagement is used to rotate backward the linkage with sprocket wheel dexterously, it is ensured that it is coaxial that the foot-driven lever on both sides swings up and down with left and right foot-driven lever axle, makes the no longer 360 degree rotations of both sides foot-driven lever, only it is by backswing 120 degree, it is to avoid human knee damages；
2, using double chain wheel to drive, it is ensured that trailing wheel longitudinal axis does not offsets, laborsaving 20% saves time 60%.
