Key features

• •【Bicycle Lock with Alarm and Chain Lock Set】 These chain locks are made of extra-thick steel and zinc alloy, anti-cutting, anti-shearing, and anti-sawing. Each bike lock comes with three keys and a built-in alarm function with motion detector. This high-quality 6 mm x 1.5 m bike lock chain set provides double protection for your bike. Suitable for bicycles, motorcycles, scooters, e-scooters, etc.
• •【Durable Bike Lock】The bike lock with key includes an additional set of spare batteries. The battery is long-lasting and easy to replace. The battery lasts for about 1 year. When the device emits a "ge ge ge" beep, the battery is empty. Please be careful not to damage the internal structure when replacing the battery.
• •【Scratch-Resistant Protection】The motorcycle lock is wrapped in a dust- and tear-resistant nylon fabric for additional protection of your equipment. Never worry about scratching your motorcycle or other equipment with the chain again! Furthermore, the case is fully enclosed and therefore well protected against dirt and corrosion. Because the keyhole can be covered, the motorcycle lock is well protected against dust, dirt, and corrosion. As a result, the lock will last a long time.
• •【Strong Protection, High Security Bike Lock】The high-quality extended bike lock features a 150 cm chain length and a weight of 1.34 kg, better combining security and portability. You can easily wrap the robust chain lock around your bike rack or carry it in your backpack. The 150 cm length is more flexible, allowing you to secure the bike to a wider range of fixed objects. It's also long enough to lock multiple bikes at once.
• •【110 dB Alarm】 Our security lock features a built-in motion detector that triggers an alarm as soon as the lock is moved or someone tampers with it. The piercing 110 dB siren draws attention to the lock and deters burglars and thieves. The enormous volume will certainly not be bearable for anyone attempting to tamper with it. The lock can also be used without the alarm sound.
• •【Extremely Durable E-Scooter Lock】: Particularly secure multi-disk locking cylinder protects against lock-picking theft; ideal for motorcycles, e-bike locks, e-bicycle locks, and e-scooter locks. This bicycle alarm not only protects against theft, but more importantly, the alarm sound can immediately alert you to the situation.
