A foldable bicycle comprises a front frame (1), a rear frame (21), and a seat tube (20). The front frame (1) and the rear frame (21) are foldable with respect to each other. In a first aspect, a single release clamp (12) releases the front frame from the rear frame in a single operation. This occurs by having the seat tube (20) slotted at the top (11). In a second aspect, the crank housing (34) is positioned in axial alignment with the seat tube (20) and one point (14) of folding occurs below the crank housing. This aspect pertains to both a men's and a women's frame.
