Quad Lock Bike Alarm and Finder

Add extra security to your ride with the Quad Lock Bike Alarm and Finder. Combining a powerful motion-triggered alarm with Apple Find My compatibility, this compact device helps deter theft and locate your bike if it goes missing.

When armed, unwanted movement triggers a 93 dBA alarm to draw attention. The built-in fingerprint sensor makes arming and disarming quick and easy, with storage for up to 20 fingerprints—ideal for shared bikes.

Locate your bike through Apple’s Find My network without a separate tracking subscription or monthly fees. A rechargeable battery provides at least six months between charges, while IP66-rated protection keeps it ready for wet and dusty rides.

FIXING OPTIONS

The Bike Alarm and Finder fixes to the Quad Lock® 360™ interface, so it works with most Quad Lock® cycle mounts and the dedicated adaptors.

Fixes to:

• Out Front Mount (Purchased after September 2025)
• Out Front Mount PRO
• Stem Cap Mount*
• Stem Cap Mount Adjustable*
• Saddle Rail Adaptor
• Bottle Cage Adaptor

*The Stem Cap Mount and Stem Cap Mount Adjustable both hold the Bike Alarm and Finder, but an anti-theft screw is not available for the stem cap itself, so the mount can still be removed with standard tools.
