[0028] Specifically, when using the foldable pedal 100 provided in this application, when the electric bicycle is out of power, the rotating shaft 121, crank 122, and connecting shaft 123 of the crank assembly 120 are connected in a Z-shape. By stepping on the pedal 130, the rotating shaft 121 is rotated, which in turn drives the wheel to rotate through the sprocket transmission assembly 110, thereby realizing the travel of the electric bicycle. When the electric bicycle is powered, the connecting shaft 123 is rotated relative to the pin 124 to fold the pedal 130 to be flush with the crank 122, thereby preventing the pedal 130 from being caught in the rider's trouser legs, skirt, etc. as the electric bicycle rotates. When the electric bicycle is parked, the connecting shaft 123 is rotated relative to the pin 124 to fold the pedal 130 to be flush with the crank 122, thereby preventing the electric bicycle from colliding with surrounding objects when parked.

[0029] The foldable pedal 100 provided in the present application includes a sprocket transmission assembly 110 and a crank assembly 120 connected to the sprocket transmission assembly 110.

When the groove and the protrusion engage, the extending direction of the connecting shaft 123 is perpendicular to the extending direction of the crank 122 .

[0033] Specifically, a limiting portion is provided on the crank 122 of the present application. When the rotating shaft 121, crank 122 and connecting shaft 123 of the crank assembly 120 are arranged in a Z shape, the groove of the crank 122 is clamped with the protrusion of the connecting shaft 123 to prevent the connecting shaft 123 from rotating relative to the pin 124 when the pedal 130 is stepped on to fold the pedal 130 to be flush with the crank 122. When the electric bicycle is out of power, the rotating shaft 121, crank 122 and connecting shaft 123 of the crank assembly 120 can be stably connected in a Z shape to ensure the stability of the assisted driving of the electric bicycle when the electric bicycle is out of power. When using the foldable pedal 100 provided by the present application, when the electric bicycle is out of power, the groove of the crank 122 engages with the protrusion of the connecting shaft 123, and the rotating shaft 121, crank 122, and connecting shaft 123 of the crank assembly 120 are connected in a Z-shape. By stepping on the pedal 130, the rotating shaft 121 rotates, which in turn drives the wheel to rotate through the sprocket transmission assembly 110, thereby realizing the travel of the electric bicycle. When the electric bicycle is powered, the connecting shaft 123 is rotated relative to the pin 124 to fold the pedal 130 to be flush with the crank 122, thereby preventing the pedal 130 from being caught in the rider's trouser legs, skirt, etc. as the electric bicycle rotates.
