Protect your ride. The Quad Lock® Bike Alarm and Finder stops a theft as it happens, and helps you find your bike with Apple Find My. MOTION ALARM A nudge sets off a warning. Keep tampering and it builds to a full 93 dBA alarm, loud enough to send most thieves running. FIND MY LOCATION Find your bike in Apple Find My, already on the iPhone you carry. Arm and disarm with your fingerprint, no phone or code needed, and store up to 20 fingerprints, so family and friends can arm and disarm it too. No new app, no subscription. STAYS ON THE BIKE Included anti-theft screws hold it firmly to the bike, so it can't be twisted off and binned like a stick-on tag. IP66 weather resistant, and up to 6 months on a single charge.
