Disc brake alarm

Compact Motion-Sensor Bike Alarm

A small but powerful alarm that mounts directly to your bike for added theft deterrence. It can be securely bolted through a disc brake hole or fitted through the spokes, making it versatile and discreet.

The built-in motion sensor triggers an initial warning beep if the bike is disturbed. Continued movement activates an extremely loud alarm to draw immediate attention and discourage theft.

⚠️ Alarm only – this is not a physical lock. Always secure your bike to a fixed object with a proper lock.

Key features:

  • Compact and lightweight design

  • Fits disc brake holes or spokes

  • Motion-activated warning beep

  • Escalates to a very loud alarm with further movement

  • Ideal as an extra layer of security
