Secure Your Bike with Confidence

Parking your motorcycle doesn’t have to be stressful. The Motorcycle Disc Lock Alarm includes a motion-sensing alarm system designed to help deter theft designed to keep your ride safe. Whether it’s a quick stop or overnight parking, you can feel confident knowing your motorcycle is locked down with smart security.

Fast and Easy Locking

Simply click the lock onto your brake disc and listen for the beep confirming activation. After five seconds, the alarm arms automatically with no extra steps required. If anyone tampers with your bike, the motion sensor triggers a 120dB alarm, producing a 120dB alarm sound when triggered.

Built Tough for Real Protection

The lock’s body is made from heavy-duty aluminium alloy that resists cutting, prying, and break-in attempts. With an IP67 waterproof rating, it stands up to rain, splashes, and even full submersion up to three feet deep. The rechargeable lithium battery lasts up to six months on a single USB-C charge.

Universal Fit and Convenience

Designed to fit most motorcycles and bikes with disc brakes up to 2.36 inches wide, this compact and lightweight lock is easy to carry. It also comes with a 5-foot reminder cable so you never forget to remove it before riding.
