ABSTRACT:
A rocking pedal (10) essentially comprises a lower pedal frame (12) having a side fitting (14) for rotational adaptation to a bicycle crank (16). A lower hinge (18) uses hinge pin (21) to couple with an upper hinge (20) that is fixed to the bottom of upper pedal frame (22). Cushion pads (24) are inserted between lower pedal frame (12) and upper pedal frame (22) on each side of joined lower hinge (18) and upper hinge (20) to make rocking pedal (10) more comfortable.
