<p>A bicycle has a lockable horizontal hinge arranged on the bicycle frame. The articulated parts of the frame may swivel around the axis of the hinge after the hinge is unlocked. The parts (11, 14, 16, 18) of the frame may be moved in a parallel direction in a plane by means of horizontal telescope means (27) and/or levers (33, 34) that can swivel around a vertical axis.</p> |
