Motion-Activated Bike Alarm with Apple Find My Location Support.
The Quad Lock Bike Alarm and Finder combines a three-stage motion alarm, Apple Find My support and fingerprint control in one compact security device.
A small movement triggers a warning before continued interference activates the full 93 dBA alarm. Apple Find My can then help locate the bike if it is taken.
Mount or Adaptor Required
The alarm attaches through the Quad Lock 360 interface and requires a compatible Quad Lock cycle mount or dedicated adaptor, sold separately. It does not mount directly to the bike using the included screws alone.
Compatible options include:
- Out Front Mount purchased after September 2025
- Out Front Mount PRO
- Stem Cap Mount or Stem Cap Mount Adjustable
- Saddle Rail Adaptor
- Bottle Cage Adaptor
Please note: Mounts and adaptors shown in the product images are not included unless specifically stated.
Alarm, Fingerprint and Find My
The three-stage alarm escalates from an initial warning to its full 93 dBA output. An integrated fingerprint reader allows the alarm to be armed or disarmed without entering a code or opening an app. Up to 20 fingerprints can be stored for trusted family members or other regular users.
The location function works through Apple Find My with no separate tracking subscription. It is not standalone GPS: location updates rely on Apple’s Find My network and nearby compatible Apple devices. Android location networks are not supported.
The alarm should be used alongside a strong bicycle lock secured to an immovable object.
Compact and Weatherproof
The IP66-rated polycarbonate and nylon housing weighs only 22 g. Its internal rechargeable lithium battery provides up to six months of use, with a USB-C to magnetic pogo charging cable included.
