摘要

The present invention is a multi-mode combination alarm and locking apparatus for bicycles, motorcycles and the like. The case of the combination alarm and locking apparatus can be attached to a bicycle or the like by a hollow bracket which can detachably mounted to a tubular section of the bicycle frame. In the preferred embodiment the combination alarm and locking apparatus includes a U-bolt lock. In an alternative embodiment the combination alarm and locking apparatus can be used in conjunction with a U-bolt lock. The combination alarm and locking apparatus also has a cable lock which has an elongated flexible cable with a conductive core and is retained by a retractable spool. The spool is releasibly engaged with a releasible rachet mechanism which controls the retraction of the spool. The combination alarm and locking apparatus further provides a multi-mode alarm protection to the bicycle, including the motion detection, the battery compartment door tampering detection and the cable lock continuity detection, all operable with a single key.
