BANGTING 4FT Smart Alarm Bike Lock - 110dB Remote-Controlled Siren & 8mm Anti-Theft Chain with Key for Bicycle, E-Bike, Scooter, Motorcycle (Black)

20% Off

Why we love it

Maximum security and sound alarm.
Weatherproof with scratch protection.
Includes everything you need.

Main Highlights

🔐 【Remote-Controlled 110dB Alarm & Key Access】 Take control of your security! The wireless remote conveniently ARMS and DISARMS the built-in 110dB alarm on the lock head. When the alarm is active, it will sound upon impact. For ultimate reliability, the lock itself is always opened using a physical, tamper-proof key. This smart system separates alarm control from physical access for enhanced security.
🚨 【Instant Sonic Deterrence】 The alarm sensor is built directly into the lock head. Once armed, any attempted theft, cutting, or rough handling triggers an immediate, piercing 110dB siren from the lock itself. This loud blast (as loud as a jet engine) effectively startles thieves and alerts everyone in the vicinity, turning your lock from a passive barrier into an active guardian.
💪 【8mm Manganese Steel Chain & Drill-Resistant Lock】 The physical heart of the security is a 8mm thick, hardened manganese steel chain, highly resistant to bolt cutters and hacksaws. The lock body is constructed from reinforced zinc alloy to shield against drilling and physical attacks, ensuring the mechanical core is as tough as the electronic alarm is loud.
🌧️ 【WeatherReady Design: IP65 Waterproof & Scratch-Free】 Built for the real world. The entire lock head with its integrated alarm is rated IP65, fully protected against rain, dust, and water sprays. The chain's durable fabric sleeve prevents scratches on your bike's finish and stops the chain from rusting, ensuring long-term performance and aesthetics.
