Here we have an ear piercing Alarmed disc lock. Housed in a compact however robust hi tensile chrome body and featuring a 7mm hardened locking pin. Perfect when you’re out and about on those shorter journeys such as maybe popping to the mother in laws? Self-arming, the microprocessor controlled motion sensor will trigger the alarm when your bike is moved. A confirmation ‘beep’ sounds when locked – you are now armed. A trio of warning ‘beeps’ will alert you that disturbance is taking place. If within 15 seconds your bike is under further attack the piercing siren will sound.
