A foldable bicycle frame mainly comprises a steering device bicycle frame body (1), a front bicycle frame body (8), a rear bicycle frame body (19), a lower supporting bicycle frame body (9) and a lock element device, wherein the steering device bicycle frame body (1), the front bicycle frame body (8), the rear bicycle frame body (19), the lower supporting bicycle frame body (9) and the lock element device are installed below a steering rod. The foldable bicycle frame is characterized in that the lock element device is mainly composed of a lock element connection shaft (13), a spring (21) and a lock element (15). The front bicycle frame body (8) and the steering device bicycle frame body (1) are hinged through a connection lug by means of the connection shaft; the lower supporting bicycle frame body (9) and the steering device bicycle frame body (1) are hinged through a connection lug through the connection shaft; the front bicycle frame body (8) and the rear bicycle frame body (19) are hinged through a connection lug through the connection shaft; the lower supporting bicycle frame body (9) and the rear bicycle frame body (19) are hinged through a connection lug through the connection shaft. Besides, the lock element device is disposed between the front bicycle frame body (8) and the rear bicycle frame body (19), so that a user only needs to slightly pull up an opening handle (16) on the lock element (15), a lock hook (20) on the lock element (15) is dehooked from a lock shaft (10) on a lock hook groove (12) of the front bicycle frame body (8), and at the moment, the front bicycle frame body (8), the rear bicycle frame body (19), the steering device bicycle frame body (1) and the lower supporting bicycle frame body (9) can be conveniently folded.
