How the Alarm Works

Slide the jaw over your brake disc and push the 7mm pin through one of the holes. Locking it arms the alarm. If someone touches the bike, it gives 5 warning beeps. If the movement keeps going, a 130dB siren goes off and keeps going. When everything is still for 10 seconds, it re-arms itself. Wind and a cat on the seat will not set off the full siren.

The Real Problem

Bike Thieves Work in Silence. A Quiet Lock Buys Them Time.

A plain disc lock just sits there while someone works on it. Nobody notices. Thieves count on the quiet.

FAQs

Everything You Need to Know.

Plain answers to the questions we get the most.

Will it fit my bike?

The 7mm pin fits the drilled holes on standard motorcycle and scooter brake discs, front or rear. If it does not fit, you get a full refund.

How loud is it?

130dB. At close range it is painful, and it carries across a parking lot and up to the apartments above.

Will wind set it off?

It reacts to real handling, not wind. Light bumps give 5 warning beeps first. The full siren only goes off if the movement keeps going.

Will I set it off unlocking it?

If you bump it, you get the warning beeps first. Turning the key shuts it off.

What if I forget it is on?

The hi-vis cord loops from the lock to your handlebar, so you see it before you ride.

What batteries does it use?

Standard LR44 cells, included. They last up to 6 months and take seconds to swap.

Can it stop an angle grinder or a van?

No lock stops a determined thief with power tools, and two people can lift a bike. The alarm takes away the quiet they count on, which makes most of them walk away.

What's your guarantee?

30 days. If it does not fit or you are not happy, send it back for a full refund.
