Abstract: An assembly includes a face plate which is mounted to an exposed wall stud in an enclosure such as a garage. The ends of a U-shaped locking member formed from a bar of hardened steel extend through transverse openings in the face plate and encircle a portion of a bicycle frame. An eye is formed on one end of the locking member and a padlock is placed through the eye to prevent withdrawal of the locking member from the face plate. In a first embodiment of the invention the face plate is mounted to the exposed edge of the wall stud on the interior of the enclosure, and in a second embodiment the face plate is mounted to the outside surface of the wall defined by the wall stud.
