Abstract: A wheel of a bicycle has a standard or undersized hub mounted on a wide rim using offset spokes in order to correspondingly offset the hub and a rear cog or pulley to one side. The offset hub provides chain or belt clearance between a chain or belt, a tire and a rim edge of the wide rim. An undersized tire may be mounted to the wide rim by providing mirrored inclined surfaces such that tire beads of the undersized tire may ride on the mirrored inclined surfaces and are thereby guided outwardly from a center trough of the wide rim to opposing bead seats of the wide rim during inflation of a tube disposed within the undersized tire.

Abstract: A bicycle lock bracket is formed by an elongated metal strap having an aperture in each end and folded in a loop with its opposite ends overlapped and juxtaposed with the apertures aligned. The strap is adapted to encircle a bicycle frame tube or other tube, rod or post, so that a cable lock body is held securely in place between the strap and the frame tube. The juxtaposed ends of the strap are attached together by bolts or other fasteners so that the cable lock body is tightly retained within the bracket when the lock is open. Inserting the cable through the aligned apertures into the lock body secures the strap, lock body and cable to the mounting tube.
