The invention relates to the technical field of vehicles, in particular to a portable folding bicycle. The front handle support rod comprises a front handle support rod, which is a two-stage telescopic rod. The handle support rod is connected with a lock, the upper nut of the handle support plate is fixed with a handle, the lower end of the handle support rod is rotated and connected with a front wheel, the lower end of the handle is rotated and connected with a cross beam rod, and the other end of the cross handle rod is vertically hinged and connected with a seat support rod. The bottom of the seat support rod is rotated and connected with a rear wheel, and the two ends of the rear wheel are also provided with a baffle, which is connected to the two ends of the rear wheel shaft and fixed to the lower end of the seat support rod through a nut. The two ends of the baffle are also provided with a foot pedal, which is connected with the rear wheel tooth chain, and the handle support rod is also connected with the seat support rod with a folding cross beam, and the seat support plate is also connected with the seat support rod. Seats are installed. The folding method of the invention is simple and labor-saving, and the bicycle has simple structure and light weight.
