The invention discloses a novel folding bicycle frame which is mainly composed of a steering device (2) installed below a steering rod, an upper frame and a lower frame. The novel folding bicycle frame is characterized in that the upper frame is divided into an upper frame front folding part (9) and an upper frame rear folding part (20), the lower frame is divided into a lower frame front folding part (7) and a lower frame rear folding part (25), the lower frame front folding part (7) is hinged to the lower portion of a port of the lower frame rear folding part (25) through a hinge shaft, the upper frame front folding part (9) is hinged to the lower portion of a port of the upper frame rear folding part (20) through a hinge shaft, the lower frame front folding part (7) is hinged to the steering device (2) through a hinge shaft, the upper frame front folding part (9) is hinged to the steering device (2) through a hinge shaft, the steering device (2), the upper frame front folding part (9), the upper frame rear folding part (20) and the lower frame front folding part (7) form a triangular structure, at the moment, the frames and the steering device (2) can be rapidly folded, and therefore the purposes of saving space and facilitating carrying are achieved. In addition, the novel folding bicycle frame has the advantages of being simple in structure, easy to fold, not prone to damage after being used for a long time, flexible to fold and the like.
