ABSTRACT:
A quick-release clipless pedal includes a cleat to be secured to a shoe sole and a pedal body to be mounted on a pedal shaft and releasably retaining the cleat. The cleat has first and second engaging parts respectively formed on front and rear ends thereof. The pedal body includes a frame portion and a tubular portion which partitions the frame portion in a transverse direction. The tubular portion receives one end of the pedal shaft. The frame portion has front and rear ends respectively formed with an opening. The pedal body further includes a pair of cleat engaging members respectively provided on upper and lower sides of the tubular portion and respectively having a claw portion to receive releasably the first engaging part of the cleat, and a pair of retaining units revertably engaging the second engaging part of the cleat. The cleat is rotatable relative to the pedal body so as to disengage the first engaging part from the claw portion. Rotation of the cleat causes the cleat to push hook units of the retaining units rearward, thereby causing the hook units to pivot and allow a lateral disengagement of the cleat from the pedal body.
