A bicycle wheel rim includes a rim body and a braking plate. The rim body includes annular first and second tire retaining walls adapted for retaining a bicycle tire therebetween, and a spoke mounting portion. Each of the tire retaining walls has a radial inner edge proximate to an axis of the wheel rim, a radial outer edge adapted for retaining the bicycle tire therebetween, and a lateral outer surface opposite to the other one of the tire retaining walls. The rim body further includes an annular spoke mounting portion which interconnects the radial inner edges of the tire retaining walls and which is adapted for mounting spokes thereon. The braking plate projects integrally from the lateral outer surface of the first tire retaining wall, and has two opposite brake pad contacting surfaces adapted to be contacted by brake pads of a brake device.
