Abstract: A bicycle wheel rim for assembly with a plurality of spokes includes a wheel rim body having two opposite annular sidewalls, an annular intermediate wall connected between the sidewalls, and an annular rib connected between the sidewalls opposite to the intermediate wall. The intermediate wall is formed with a plurality of angularly spaced-apart spoke holes, each of which is adapted to retain a corresponding one of the spokes. Each sidewall is formed with a plurality of angularly spaced-apart cutout portions. Access to an interior space confined by the sidewalls, the intermediate wall and the rib is permitted through the cutout portions for attachment of the spokes to the spoke holes, respectively.
