Abstract: A cable lock storage structure adapted for selective mounting as upon a bicycle frame and having a locking cable stored on a spring loaded reel retractor assembly provided therein. The cable is selectively extendable from the housing so as to be wound through the bicycle frame and around an adjacent fixed structure so as to shackle the two together. The free end of the cable is adapted for selective locking engagement with a cable lock mechanism integrally provided in the housing so that the cable forms a closed loop locking assembly with the housing. A pawl lock mechanism is integrally provided in the housing to selectively and lockably engage the reel retractor so as to prevent retraction of the extended cable. The pawl lock mechanism is adapted to selectively be disengaged to permit retraction of the cable into the housing for storage when not in use.
