Quad Lock Accessory Bike Alarm Finder

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.

Requires an Apple device with 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.

COMPATIBILITY

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

^{PLEASE NOTE: Some advanced setups, such as pairing with a Wireless Charging Head and Light/Camera Adaptor, need the Quad Lock® Anti-Theft Screw Kit, sold separately.}

^{*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.}

^{Please refer to the Compatibility Guide for details.}
