The ULAC Air Alarm is a compact alarm disc lock for e-bikes and motorcycles. Its movement and shock sensors activate a 120 dB alarm when the locked vehicle is disturbed, while cut detection provides a second audible alert if the lock itself is attacked. Auto arming makes it straightforward to secure your bike when you stop.
Inside the lightweight aluminium-alloy body is a steel frame and stainless-steel internal assembly. The 6 mm steel pin provides the locking connection, while the anti-dust lid helps protect the cylinder. At just 156 g, it adds useful security without becoming a burden in a riding bag.
The Air Alarm is rain proof for everyday outdoor use and includes three high-security Abloy keys with 2,000 unique key combinations. You also receive an orange reminder cable, a pre-installed CR2 battery, an Allen key and a protective storage bag, making this a practical choice for commuters, e-bike owners and motorcycle riders who want an audible warning as well as a physical lock.
