[0002] A shared bicycle, also known as an electric shared bicycle or an electric bicycle, is a bicycle equipped with an electric sharing system. It provides additional sharing through a motor and a battery, making cycling easier, especially when going uphill or on a long-distance ride. Shared bicycles are becoming increasingly popular in urban commuting, leisure cycling, and tourism.

[0003] Most of the existing shared bicycles are of an integrally formed structure. When a water-expanded vertical pipe fork of a shared bicycle fails, the whole self-care bicycle needs to be disassembled for replacement, which is rather inconvenient.

A seat tube is fixedly installed on the upper left side of the body profile. A seat tube gland is installed at the upper end of the seat tube;

[0008] A water-expanded vertical pipe fork. The water-expanded vertical pipe fork includes two pipe forks. Front fork legs are provided at the lower ends between the two pipe forks. The middle parts of the pipe forks are fixedly connected by two front fork connecting plates. A handlebar is fixedly installed on the upper ends of the two pipe forks through a handlebar pressing block. A front fork vertical tube is installed on the lower front fork connecting plate through a rear pressing block. The front fork vertical tube is inserted into the head tube and penetrates through the upper front fork connecting plate. A limit nut is threadedly connected to the upper end of the front fork vertical tube;

[0009] A tail fork. The tail fork includes two rear fork tubes. Rear fork forgings are provided at the rear ends of the two rear fork tubes. The lower ends of the two rear fork tubes are fixedly connected to the body profile. The upper ends of the two rear fork tubes are fixedly connected to the seat tube.

[0010] Further, a footrest is rotatably installed on the lower side of the rear end of the body profile.

[0011] Further, a limiting hook is provided on the footrest, and a limiting slot matching the limiting hook is provided on the body profile.

[0012] Further, a limiting spring is hooked on the lower side of the front end of the body profile, and one end of the limiting spring away from the body profile is hooked to the rear pressure block.

[0013] Further, basket mounting holes are provided on both of the two pipe forks.

[0014] Compared with the prior art, the beneficial effects of the present utility model are at least as follows:

[0015] By providing the hydroformed upright pipe fork, by removing the limiting spring and the rear pressure block, removing the nut, and then pulling out the front fork vertical pipe, the hydroformed upright pipe fork can be disassembled as a whole at this time. When a failure occurs in the hydroformed upright pipe fork of the shared bicycle, it is more convenient to replace it.
