A foldable bike frame is mainly composed of a steering device (1) installed below a steering rod, a front bike frame body (8), a rear bike frame body (19), a lower supporting bike frame body (9) and a lock catch device. The foldable bike frame is characterized in that the lower supporting bike frame body (9) with connecting lugs (7 and 23) at the two ends is arranged to be a damping device. As the lower supporting bike frame body (9) is arranged to be the damping device, it is unnecessary to additionally install a damping device on the bike frame, the damping purpose can be achieved, the structure of the bike frame can be simplified, and the cost can be lowered. As the front bike frame body (8) and the lower supporting bike frame body (9) are hinged to the steering device (1) and the rear bike frame body (19) through connecting shafts via connecting lugs, the steering device (1) and the lower supporting bike frame body (9) can be rapidly folded, and the purposes of saving space and facilitating carrying are achieved.
