ABSTRACT:
A lever arm lock for a conventional quick-release hub assembly includes a cover mountable to a first skewer rod end nut supporting a quick-release lever arm. The cover is secured to the end nut with a locking mechanism (combination, magnetic, key, etc.) and maintains the lever arm in a locked position making it impossible to remove the hub. A second skewer rod end nut opposite the first end nut is formed with a substantially smooth outer surface that is continuously inclined with respect to the axle. This surface configuration prevents removal of the locked hub assembly by turning the second end nut with a pliers or other tool. The lever arm lock also prevents the hub from being jarred loose on impact with curbs, rocks, etc. The end nut assemblies have extensions which abut the frame thereby preventing loosening thereof for unauthorized removal.
