Anti-Theft Disc Brake Lock

The Anti-Theft Disc Brake Lock features an integrated motion and vibration sensor that triggers a 110dB alarm when tampering, impact, or movement is detected. The alarm’s volume is comparable to a chainsaw or rock concert, making it highly effective in drawing attention and deterring theft attempts. Sensitivity is calibrated to detect even slight shifts in the wheel, but it is designed to avoid false alarms from wind or passing traffic vibrations. Once triggered, the alarm will sound for 10 seconds, then automatically reset, ready to detect further tampering.

This lock is engineered with a universal fit design to accommodate most motorcycles, scooters, and bicycles equipped with disc brakes. It secures directly through the brake disc’s ventilation holes, with compatibility for disc brake thicknesses up to 7mm and hole diameters larger than 6mm. The compact form factor allows for use on both front and rear wheels. Before purchasing, measure your disc brake dimensions to confirm compatibility for the most secure fit.

The body of the lock is constructed from hardened stainless steel and high-strength zinc alloy for exceptional resistance to sawing, prying, and drilling. The outer casing incorporates ABS weather-resistant housing to protect the electronic components from moisture, dust, and debris. This combination ensures the lock remains fully functional even in extreme outdoor conditions, providing long-term reliability.

The lock is rated for all-weather performance, meaning it can withstand rain, humidity, UV exposure, and temperature fluctuations from -20°C (-4°F) to 60°C (140°F). The corrosion-resistant metals and sealed electronic housing prevent internal damage caused by water ingress. This makes it ideal for riders who park their vehicles outside regularly.

The unit comes pre-installed with 6 button cell batteries (LR44/AG13 type), providing 6–8 months of standby use under normal conditions. When the alarm volume becomes noticeably weaker, or response times slow, it’s time to replace the batteries. Replacement involves simply unlocking the device, removing the alarm module, and swapping the cells—no special tools required. Spare batteries are inexpensive and widely available at hardware stores, supermarkets, or online.

To ensure longevity:

• Clean the lock monthly with a dry cloth to remove dirt and dust.
• Lubricate the keyhole with a graphite-based lubricant every 2–3 months to prevent sticking.
• Check battery condition regularly and replace as needed.
• Store in a dry place when not in use for extended periods.
