The invention discloses a motorcycle lock which comprises a lock body and a lock beam, wherein the lock body is internally provided with a lock core, a storage battery, a switch and an alarm loop; the lock beam is internally provided with a small bulb and a relay; the storage battery, the switch, the relay and the small bulb are sequentially connected in series to form a loop; the storage battery is in series connection with the switch and then is connected with the alarm loop in parallel; the alarm loop comprises an electric bell and a normally closed auxiliary contact of the relay; and the electric bell is in series connection with the normally closed auxiliary contact of the relay. After the motorcycle lock is cut off by a hydraulic shear, a wire in the lock is also cut off, the small bulb in the lock beam cannot light, and the electric bell in the lock body rings, so that an owner of a motorcycle is reminded that a person steals the motorcycle. The motorcycle lock is simple in structure, and the safety performance is improved greatly.
