A quick release device includes an axle tube, a pressing unit, and a driving unit. The axle tube extends through a bicycle frame, and has a plurality of through holes. The pressing unit includes a plurality of pressing members disposed respectively and movably within the through holes in the axle tube, and a pushing member movable axially in the axle tube. The driving unit includes a movable shaft. When the driving unit is changed to a locking state, the movable shaft moves the pushing member such that the pushing member pushes and moves the pressing member to press against the bicycle frame. When the driving unit is changed to a release state, the movable shaft moves the pushing member away from the pressing members to allow the pressing members to move radially away from the bicycle frame.
