The Ulac Air Alarm Disc Lock is a new addition to the Neo Alarm family. It's lightweight yet incredibly robust. Using advanced material science, it offers maximum strength. With a powerful 120 dB alarm system, it provides top - notch protection for your E - Bikes and Motorcycles. This lock combines shock/movement sensors, an alarm system, an alloy body, and a stainless - steel internal assembly, which showcases its excellent engineering design. Key Features: 120dB shock and cut alarms, rain - proof, 4 - digit combo, aluminum body with a steel frame, a protective storage bag, weighs only 156g, has an anti - dust lid, a 6mm steel pin, and auto - arming. Specifications: Lock dimensions are 68 x 46 x 86mm, weighs 243g (0.53lbs) without additional items, uses a CR2 x 1 battery, and the main materials are aluminum alloy and stainless steel. The box includes an Allen key, a pre - installed CR2 battery, and a 4mm x 140cm orange reminder cable.

Using the Ulac Air Alarm Disc Lock is easy. First, open the lock by entering the 4 - digit combo. Then, attach it to your E - Bike or motorcycle. The lock will auto - arm itself once it's in place. If someone tries to cut or move it, the 120dB alarm will go off. Keep in mind that although it's rain - proof, avoid submerging it in water for a long time. The anti - dust lid helps keep dirt out, but you can clean it gently with a dry cloth every now and then. When the battery runs out, replace the CR2 battery with a new one. The reminder cable can be used to remind you not to forget the lock. Store the lock in the protective bag when not in use to keep it safe.
