Maximum Anti-Theft Protection: Bicycle Lock with Alarm & 110dB Loud Siren
Standard bicycle locks can be cut silently in seconds. The CycleAddons bicycle lock with alarm adds an active electronic defense system that immediately deters thieves.

Why Cyclists Rely On This Smart Alarm Cable Lock:

- Quick-Release Frame Bracket: Mounts neatly onto your seat post or frame tubing. Press the quick-separation button to release the lock in seconds when parking.
- Weatherproof & Water-Resistant Seal: Features an integrated silicone cap over the alarm module and key cylinder to guard against rain, dust, and moisture.
