Abus 440A Alarm U-Lock - 4.2 x 6.3", Keyed, Black/Red, Includes bracket

The Abus 440A Alarm U-Lock is a high-security lock designed to protect your bike from theft. It is equipped with a 3D Position Detection System, which registers any movement or tampering with the lock. The lock features a hardened 12 mm round shackle, made of specially hardened steel, to resist cutting and tampering. In the event of an attempted break-in, the lock sounds an alarm at a volume of at least 100 dB for 15 seconds, followed by automatic reactivation. The lock also includes CR2 batteries for power. The shackle, body, and load-bearing parts of the locking mechanism are all constructed from hardened steel, making it resistant to tampering and break-ins.
