Handle stem structure convenient for wiring and electric bicycle

The handlebar vertical pipe structure is characterized by comprising a pipe body of a hollow structure, a wire outlet communicated with a bicycle head pipe is formed in the bottom of the pipe body, a wire inlet communicated with a bicycle handlebar is formed in the side wall of the front end of the pipe body, and a partition plate is arranged in the pipe body. The partition plate divides the interior of the pipe body into a first cavity and a second cavity, the two ends of the first cavity are communicated with the wire outlet and the wire inlet respectively, one end of the second cavity is closed, the other end of the second cavity is communicated with the wire outlet, and a first wire passing hole communicated with the first cavity and the second cavity is formed in the partition plate; the bicycle handlebar has the advantages that the front fork wire set stretches into the handlebar head from the wire inlet and then stretches into the front fork vertical pipe, when the handlebar and the head pipe rotate re
