Blockstory Disc Lock Alarm 110dB

The Blockstory Disc Lock Alarm combines a hardened steel disc lock body with a 110-decibel motion-activated alarm that triggers on any movement attempt, providing both physical and acoustic deterrence. The disc lock format — a circular body with a short shackle that passes through the motorcycle brake disc — is the most effective physical deterrent for motorcycle wheel movement because it cannot be removed without destroying the disc or the lock. The 6mm shackle is made from hardened steel with a boron alloy core that resists cutting. The 110dB alarm activates within 3 seconds of detecting movement above the set sensitivity threshold, audible at distances up to 100 meters in open environments. The alarm runs on a standard CR2 battery with an operational life of approximately 12 months under normal use patterns. A warning cable reminder connects between the lock and the handlebar, preventing the rider from moving the motorcycle with the disc lock engaged. Waterproof to IP67 standard. Dimensions: 70mm diameter, 6mm shackle. Weight: 310g.
