A stretchable bicycle comprises a separate but connectable crossbar consisting of a sliding bar (11) extended rearward from a head tube (12) of a front frame and a cross tube (22) fixed to a support tube (26) of rear frame (20) the cross tube (22) being adapted to telescopically receive and permit the sliding bar (11) to project from its rear end. Also, two quick-releases (30,31) are provided for fastening the sliding bar at both ends of the cross tube respectively. Hence, a distance between two wheels can be adjusted by sliding a desired portion of the sliding bar (11) inside the cross tube (22). <IMAGE>
