A folding bicycle, comprising a hidden self-locking seat tube clamp (1), a longitudinal rotating shaft folding frame (2), a brake (3), a conical detachable vertical handlebar tube (4), and a steel blade transmission system (5). The hidden self-locking seat tube clamp, the brake, the conical detachable vertical handlebar tube, and the steel blade transmission system are respectively mounted onto the longitudinal folding frame. By means of the technical solution of the present invention, the weight of a folding bicycle having a 14 inch or 16 inch wheel diameter can be reduced by around 1080 grams, such that the total weight of the folding bicycle is less than 6000 grams, which is therefore more convenient to carry. |
