The invention discloses a foldable pedal of a pedaled bicycle. The foldable pedal of the pedaled bicycle consists of a foot bar positioning hole 1, a foot bar 2, an angle releaser 3, a pedal positioning supporting piece 4, at least three connecting rotation sleeves 5 and a pedal 6, wherein the foot bar positioning hole 1 is formed in the front end of the foot bar 2 in a welded manner; the foot bar 2 is fixedly connected with a supporting shaft on a frame of the pedaled bicycle by the foot bar positioning hole 1; the angle releaser 3 is arranged below the front of the foot bar 2; one side of the bottom of the pedal 6 is welded with the connecting rotation sleeves 5; the connecting rotation sleeves 5 are in linking connection with the foot bar 2 in a penetrating manner; by using the connecting rotation sleeves 5, the foot bar 2 is connected with the pedal 6, and the foot bar 2 and the pedal 6 can be folded in an overturning manner; and by using the pedal positioning supporting piece 4 arranged on the foot bar 2, a limiting supporting effect on the pedal 6 which overturns on the foot bar 2 at an angle is achieved.
