Abstract: A self-locking safety retaining mount for use with bicycles utilizing quick-release hubs for front wheel mounting. The mount comprises a left and right configured pair of devices, each of which provides positive closure of the open-ended axle receiving slot in the dropout at the end of each leg of the front forks of a bicycle by rotating a positive barrier load-bearing surface latch across the end of the axle receiving slot. The latch is retained in the closed position by the forces exerted by an accidentally loosened or undertightened hub on the load-bearing surface formed by the closed latch in cooperation with a pivot.
