Touch it and the whole street hears about it. A 120dB alarm disc lock that snaps onto your brake rotor in a second. Bump it and it warns, keep going and it screams. Rechargeable over USB-C, waterproof, and tough enough to shrug off a hammer or a pry bar. 120dB alarm – the shock sensor gives 3 warning beeps, then a full 15-second alarm if they keep at it. Press to lock – push it shut, no key needed. Unlock with the key. USB-C rechargeable – 500mAh battery charges in about 70 minutes and lasts about 5–6 months. IP67 waterproof – rain, wash days and dew don't stop it. Aluminium alloy body – rust-proof, knock-proof and pry-resistant. 1.8m safety rope – copper-core rope to run to your bars as a reminder, or through the wheel. Fits standard brake discs – motorcycles, scooters and bicycles. In the box: alarm disc lock, 2 keys, USB-C charging cable and 1.8m safety rope.
