The detail

A 10 mm hardened pin lock with a built-in motion sensor. Bumping the bike triggers a warning chirp; sustained movement triggers the full alarm. Includes a bright reminder cable so you do not ride off with it fitted.

The problem

A parked bike in a public car park is an easy target and easy to move quietly.

The solution

A physical lock that is also loud, plus a visible reminder cable.

Why it matters

Deterrence and attention, in one small unit you can carry.

How it works

  1. 01Insert the pin through a brake disc hole and lock it.
  2. 02Arm the alarm with the key.
  3. 03Attach the reminder cable to the handlebar.
  4. 04Disarm before riding and remove the lock.

Loud enough

Tested it in the garage. Chirps first, then it is genuinely loud.
