Abstract

The utility model discloses a folding bicycle seat tube, wherein, the bottom of the seat tube tilts forwards; the front side at the bottom of the seat tube is connected with a bicycle beam or a stiffener; the rear side at the bottom of the seat tube is cut on the bias. Because the rear side at the bottom of the seat tube is cut on the bias, no convex rear side of the bottom exists, thereby trouser legs of riders can not be hooked and the problem of tearing in the trouser legs or tripping over the riders does not exist. Simultaneously, because the rear side at the bottom of the seat tube is not convex any more, the bottom of the seat tube can not injure carriers and can not damage other articles after the bicycle is folded.

Description

A kind of folding bicycle seat pipe
Technical field
The utility model relates to the structure of folding bicycle frame, particularly a kind of seat pipe of folding bicycle.
Technical background
