An improved structure for expandable bicycles to facilitate storing of a bicycle includes a cross bar which has one end fastened to the front fork of the bicycle and a sliding member slidable horizontally on the cross bar to alter the relative position of the front fork and the rear fork. The sliding member has a fastening member to fasten the head and seat of the bicycle on selected locations. Thus the bicycle may be extended as desired and stored conveniently.
