Motorcycle Disc Alarm Lock

The APC-02 Motorcycle Disc Alarm Lock is a compact, solid-steel security device that attaches directly to your bike's brake disc. Once fitted, the 6mm locking pin prevents the wheel from rotating, making it impossible to roll or ride the bike away.

The integrated alarm activates when the lock detects repeated movement or direct tampering. Unlike ultra-sensitive alarm systems, this model is intentionally calibrated to avoid nuisance triggers caused by wind, vibrations, or nearby engines ideal for daily use in busy parking areas.

The unit arms automatically with an audible beep, giving you 10-15 seconds to position it on the disc. A smart 5-second motion check ensures the alarm only sounds when it should, emitting a loud 10-second burst before resetting.

Supplied with 3 keys and spare batteries, it's a highly affordable step up from basic disc locks.
