A collapsible bicycle (1) has a frame (2) collapsible in its plane. The frame (2) includes a head tube (3) having a collapsible bicycle front side end (10) in which a front wheel fork (12), which receives a front wheel (13), is mounted. A seat stay (5) has an end (38) receiving a seat tube (39). A lever (6) is articulated at a first articulation point (50) at a collapsible bicycle rear side end (37) of the head tube (3) and at a second articulation point (49) at the end (38) of the seat stay (5) receiving the seat tube (39). The lever (6) is arranged to the collapsible bicycle front side in a riding position of the collapsible bicycle (1). A down tube (4) is articulated at a third articulation point (18) at the collapsible bicycle front side end (10) of the head tube (3) and at a fourth articulation point (24) at an end (38a) of the seat stay (5), opposite the end (38) of the seat tube (39). The first, second, third and fourth articulation points (50; 49; 18; 24) are arranged in such a way, that, for moving the collapsible bicycle (1) from the riding position into a sliding position or from the sliding position into the riding position, respectively, the end (38) of the seat stay (5) receiving the seat tube (39) is shiftable in a direction (117) towards the head tube (3) or in a direction (119) away from the head tube, respectively.
