Abstract:
A bicycle alarm system for use with a bicycle and a bicycle lock adapted to anchor the bicycle to a stationary object, the alarm system comprising:an alarm unit that connects to a bicycle and comprises an audible alarm;a lock wiring assembly that attaches onto a bicycle lock, the lock wiring assembly including multiple-conductor wiring on an outer surface of the lock comprising a plurality of conductor wires, wherein some of the conductor wires are operative wires adapted to complete a circuit when the lock is closed and are adapted to open the circuit when the lock is opened, and wherein some of the conductor wires are dummy wires that are not in the circuit;wherein the circuit completed by the operative wires is electrically connected to the alarm unit, so that breaking the circuit by opening the lock triggers the audible alarm and so that breaking the circuit by cutting any of the operative wires triggers the audible alarm;wherein the dummy wires make it difficult for a thief to select the operative wires from the plurality of conductor wires to short-circuit the operative wires in an attempt to prevent breaking of the circuit and sounding of the audible alarm while the thief opens or cuts the lock.
