A bicycle hub is adapted to be connected to a wheel rim by a plurality of spokes, each having-an insert portion to interconnect bent and head portions. The hub includes a hub shell rotatable about an axis, and an annular spoke mounting flange which extends radially from the hub shell, and which has a plurality of recesses, each extending from an outer radial surface of the flange axially to terminate at a recess base surface, and outwardly and radially to an outer peripheral surface, and a plurality of mounting holes extending from an inner radial surface to be communicated with the recess base surface. The head portion of each spoke abuts against one of the recess base surface and the inner radial surface so as to dispose the insert portion in the mounting hole. The bent portion and the head portion are confined in the corresponding recesses for protection purposes.
