Problems solved by technology

[0005] The beneficial effects of the present invention are: the present invention uses a variety of technical means to reduce the electric welding of the vehicle body; the present invention enables the portable folding upright bicycle to achieve the effect of small enough volume after being folded; the present invention adopts The latest form of folding handlebar with telescopic section makes the folding of the handlebar simpler and more effective; the present invention uses the front beam, folder and middle beam to be located on the left side, so that the folded rear wheel can be located The right sides of the front beam and the middle beam are positioned by the rear wheel buckle; the present invention adopts the positioning of the front wheel buckle connected to the rear fork after folding, so that the front wheel, the front fork and the front beam are fixed together in the folded state The present invention adopts the matching mode of the shock-absorbing bottom bracket and the shock-absorbing baffle, which not only allows the rear fork to be folded forward and downward quickly with the rear wheel, but also enables the rear fork to have a shock-absorbing effect after unfolding; and, The spring joint is used to cooperate with the joint bolt and the screw hole steel ball, which solves the difficult problem of the spring joint penetrating into the vertical hole of the polyurethane block; the five-way pipe is used to rotate and connect with the horizontal through hole at the lower part of the five-way joint. The bottom bracket is used as the folding shaft of the rear fork and has a large contact area with the horizontal through hole at the lower part of the bottom bracket, which is durable and will not loosen due to wear and tear
