The ABUS 440A U-lock adds an extra layer of security to an already-solid bicycle lock with ABUS' proven 100db alarm system featuring the 3D Position Detection System. The core of the lock is ABUS' reliable steel lock body and 12mm round shackle, which is tough enough to deter theft on its own. Add in the 100db alarm (as loud as a circular saw) and it's enough to scare away most thieves.
The intelligent alarm system is powered by long-lasting coin cell batteries for ease of use. Small bumps trigger warning beeps, while continued movement triggers the full ear-splitting alarm.
