Abstract

The invention provides a folding bicycle allowing an easy folding work and a stable and easy carrying by small force in a folded state. A lower part of a head lug 3 and a front end of a main frame 2 are rotatably connected. A rear end of the main frame 2 and an upper part of a main body frame 20 are rotatably connected. A saddle connecting bar 8 having an upper end connected to a saddle 7 in which a vertical position is made adjustable is suspended. A front end of a sub-frame 1a and an upper part of the head lug 3 are rotatably connected. A rear part of a rear sub-frame 1c and a lower part of the saddle connecting bar 8 are rotatably connected. The rear sub-frame 1c is rotatably connected to the main body frame 20. A center sub-frame 1b is rotatably connected to the main frame 2.

Description

technical field [0001] The present invention relates to folding bicycles. Background technique [0002] Japanese Patent Laid-Open Publication No. 2004-58912 shows an existing folding bicycle. Such as Figure 6 As shown, when folding the foldable bicycle, the bending of the vehicle frame 2, the folding of the handle 12, the removal of the saddle 7, the removal of the wheels 15, 16, etc. must be carried out in sequence. Therefore, the folding operation is not easy, the folding work takes time, and there is a problem that it cannot be easily folded. In addition, in order to carry the folded bicycle, it can be carried with the pocket, and there is a problem that a large amount of labor is required to carry some heavy bicycles. Contents of the invention [0003] The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a foldable bicycle that is easy to fold and can be transported in a folded...
