The invention discloses a multi-angle bicycle stand pipe structure, the height of a front fork pipe is 39-41mm, the outer diameter of the front fork pipe is 32-33mm, a connecting pipe comprises a first pressing surface, a second pressing surface, a third pressing surface and a fourth pressing surface, the first pressing surface is fixedly connected with the second pressing surface through a first arc-shaped section, the second pressing surface is fixedly connected with the third pressing surface through a second arc-shaped section, and the fourth pressing surface is fixedly connected with the third pressing surface through a third arc-shaped section. The third pressing face is fixedly connected with the fourth pressing face through a third arc-shaped section, the fourth pressing face is fixedly connected with the first pressing face through a fourth arc-shaped section, the first pressing face and the third pressing face are arranged in parallel, the distance between the first pressing face and the third pressing face is equal to or smaller than the outer diameter of the front fork pipe, and the second pressing face and the fourth pressing face are arranged in parallel. The distance between the first pressing face and the third pressing face is 32-33 mm, the included angle between the second pressing face and the horizontal plane of the front fork pipe is plus or minus 10-35 degrees, and the included angle between the fourth pressing face and the horizontal plane of the front fork pipe is plus or minus 10-35 degrees. The connecting pipe is of a structure with a plurality of pressing faces and a plurality of arc-shaped sections, and the maximum included angle between the front fork pipe and the connecting pipe reaches plus or minus 35 degrees.
