Heavy duty alarm disc lock for motorcycles, scooters and bikes with disc brakes, with a built-in motion-sensing alarm. It clamps onto the disc brake rotor and sounds a loud, high-decibel warning when it senses vibration or tampering, scaring off thieves and alerting people nearby. The body is hardened, weather-resistant alloy steel, made to resist cutting, sawing and prying. A quick one-push mechanism locks it key-free for easy daily use. It fits the disc rotor of most motorcycles, bicycles, electric scooters and dirt bikes. The black body carries a yellow "ALARM DISC LOCK" label with a 110dB alarm mark, a chrome lock cylinder and a U-shaped rotor slot. Package: 1 disc lock alarm and 2 keys.
