A bicycle hub cover assembly is installed on a bicycle hub to provide a hard, rigid protective cover for the bicycle hub. In one embodiment, the bicycle hub cover assembly has a hub shell cover, a first hub end cover, a second hub end cover and a pair of fasteners that attach the hub end covers to the axle of the bicycle hub. The hub shell cover is configured and arranged to be mounted concentrically around a center portion of the hub shell of the bicycle hub, while the hub end covers overlie the axial ends of the bicycle hub. Thus, the bicycle hub is completely enclosed, except for a small gap located between the hub shell cover and each of the first and second hub end covers. In another embodiment, the hub shell cover is eliminated.
