A bicycle wheel rim includes an annular rim body having a rim axis, and including left and right annular side walls, a pair of annular oblique walls, an annular base wall, left and right annular connecting walls, and a pair of annular tire-retaining ribs. Each of the left and right annular side walls has a radial outer edge. Each of the oblique walls extends obliquely from a respective one of the side walls toward the other one of the side walls. The base wall interconnects the oblique walls and has a radial outer side. Each of the left and right annular connecting walls extends from the base wall to connect to a respective one of the side walls. A radial distance between the radial outer side of the base wall and the radial outer edges,of the side walls ranges from 8.5 millimeters to 12.5 millimeters.
