A pedal device includes a barrel for attaching to a cycling apparatus and having a fixed seat, a movable seat slidably attached onto the barrel and having a number of recesses facing toward corresponding recesses of the fixed seat, a spring biasing device for biasing the movable seat to move toward the fixed seat of the barrel, and an attachment for attaching to a bicycle shoe and having two end catches for selectively engaging with the recesses of the fixed seat and the movable seat, and for selectively anchoring the bicycle shoe to the seats of the pedal device. The movable seat is movable away from the fixed seat against the biasing device by the attachment.
