Abrégé

A swing type transmission bicycle (100) is composed of a bicycle body (10), a chainwheel device (20), a rotation shaft, a pedaling device (30) and a group of swinging device (40). The swinging device (40) has a swing rod (60) and an oneway bearing (50) which has a centre bore (51). The rotation shaft is axially mounted in the centre bore (51) of the oneway bearing (50), and the swing rod (60) contains plural parts of socketed telescopic rod. Thereinto the end of last part of telescopic rod (62) has a radial axle hole so as that the telescopic rod can be movably arranged between the pedal (32) and the crank (31), and the front end of first part of telescopic rod (61) is mounted outside of the oneway bearing (50). When the pedaling device (30) drives the swing rod (60) to move up and down, the swing rod (60) can expand and contract passively to form axial reciprocating motion and can drive the oneway bearing (50) to cause the oneway rotation of the rotation shaft so as to make the wheels rotating. The telescopic swing type transmission mechanism for bicycle can improve riding comfort and safety.
