Come and take a look at our alarm brake disc lock. Our brake disc locks are made of high-quality aluminum alloy material. When the vehicle or brake disc lock vibrates, our lock will emit a "Di Di Di" warning alarm. After a five-second interval, the alarm will sound again and continue for 10 seconds. To deactivate the alarm, simply unlock it with the key. Our locks are suitable for motorcycles, electric vehicles, mountain bikes, etc. with brake discs.
