A quick-release device for a bicycle includes a shaft having a locking assembly at one end and an inner sleeve in another end. The inner sleeve is kept a distance apart from an end edge of a through hole of the shaft to form an inner annular trough portion at an outer end of the through hole. A threaded cylinder is insertedly connected to the inner annular trough portion. A perforation is defined in the threaded cylinder. One axial end of the threaded cylinder has a cylindrical flange. The cylindrical flange is insertedly connected to the inner annular trough portion of the shaft. A bolt is insertedly disposed in the perforation of the threaded cylinder. The bolt passes through the perforation and is inserted into the shaft to be screwed to the inner sleeve, so that the bolt presses and locks the threaded cylinder and the shaft.
