ROCKBROS LBAYG8308 Disc Brake Lock with 110 dB Alarm - Orange

Disc brake lock with integrated 110 dB alarm delivers powerful anti-theft protection for bicycles, scooters, and motorcycles. The motion/vibration sensor triggers a piercing siren at the slightest tampering, while the 6 mm hardened steel pin physically blocks the brake disc. A press-to-lock mechanism enables one-handed operation without keys, and the IPX4 water-resistant aluminum alloy body withstands rain and splashes. Powered by six included LR44 batteries, the alarm remains on standby for up to eight months, with an LED status light indicating arming and low battery. Two flat keys open the anti-drill, anti-pick cylinder, ensuring only the owner can disarm the lock. The bright orange finish increases visibility, deterring potential thieves and helping you locate your vehicle quickly.

Advantages

The combination of a robust mechanical lock and a loud 110 dB alarm provides dual-layer security. The vibration sensor is highly sensitive, reacting to even minor movements, while the hardened steel pin resists cutting and prying. The aluminum alloy body is lightweight yet durable, and the IPX4 rating means the lock functions reliably in wet conditions. The press-to-lock design allows instant locking without fumbling for keys, and the included batteries mean the alarm is ready to use out of the box.
