The invention provides a K-shaped folding bicycle. The bicycle has a main bicycle body structure that a folding handlebar 1 is connected with a front fork 2 through a folder D; a front wheel 3 is mounted on the front fork 2; the front fork 2 is connected with a front frame 4 through a folder A; and the front frame 4 is connected with a rear frame 5 through a folder B; a seat 6 is connected with a seat sliding sleeve E welded to the rear frame 5; a small pulley is arranged at the lower end of a seat tube; the rear frame 5 is connected with a rear fork 9 through a folder C; a transmission device 8 is mounted in the rear fork folder C; a rear wheel 10 is mounted on the rear fork 9; brake devices 7 are mounted on the front fork 2 and the rear fork 9; and wheel shaft buttons 11 are mounted on a front wheel shaft and a rear wheel shaft. For the bicycle, based on a big wheel, a pass through property, a folding effect and versatility are all achieved. According to the invention, the problems that wheels of an existing folding bicycle are big, folding volume is large, wheels are small so that the pass through property is poor and the use is single are solved; the multi-direction and multi-angle folding bicycle body is formed; when the A and the C are pulled up, the bicycle body is folded and shortened to form a pushing shape; when the seat is pressed to the bottom and the B is pulled open, the vehicle body is folded in half to form a hand pushing shape; and when the D is pulled open, the handlebar is put down so that the bicycle is completely folded. The bicycle has the advantages of compactness and orderliness.
