Motorcycle Disc Lock with 110dB Anti Theft Alarm

Motorcycle Disc Lock with 110dB Anti Theft Alarm

Over 46,000 motorcycles are reported stolen every year, and bikes without a visible security device are the easiest targets. This motorcycle disc lock alarm clamps onto your brake disc rotor in seconds and guards your bike with a motion sensing 110dB siren that scares thieves off before they can roll your bike an inch.

Why Riders Choose This Disc Brake Lock

A disc lock is the fastest anti theft device a rider can use: no chains to carry, no wiring to install. Clamp it on the rotor, turn the key, done. This one adds an alarm on top of the physical lock, so it works as a wheel lock, motion alarm, and visual theft deterrent in one compact unit. It fits in a jacket pocket or under the seat, ready for street parking, hotel lots, campgrounds, rallies, or long term storage in the garage.

Sensitive Auto Reset Alarm

The built in vibration sensor triggers the 110dB alarm the moment someone touches, bumps, or tries to lift your motorcycle. After sounding, the alarm resets and rearms automatically, so your bike stays protected all night without you doing a thing. Deactivating it is as simple as unlocking with the key.

Frequently Asked Questions

Does a disc lock with an alarm really stop motorcycle theft?

It is one of the most effective visual and audible deterrents you can use. The bright lock body tells a thief your bike is protected, and the 110dB siren draws instant attention the moment the bike is touched or moved. Most thieves move on to an easier target.

Will this disc lock fit my motorcycle?

Yes. It clamps onto the brake disc rotor, which nearly every motorcycle, scooter, and even many bicycles and ATVs have. No tools, wiring, or installation needed. Just clamp it on the rotor and turn the key.

How loud is the alarm and what sets it off?

The siren peaks at 110dB, about as loud as a car horn at close range. A motion and vibration sensor triggers it when someone touches, bumps, or tries to lift the bike. The alarm resets automatically and rearms itself, so it stays on guard.

Is it waterproof for outdoor parking?

Yes. The lock core and alarm housing are sealed against rain, and a tamper proof battery door keeps water and prying hands out. You can leave it on a bike parked outside in any weather.

What if I forget to remove it before riding off?

The alarm sounds the instant the wheel moves, which acts as a built in reminder before you roll. Best practice with any disc lock is to hang a reminder cable from the lock to your handlebar.

What is included and what about batteries?

You get the alarm disc lock and 2 stainless steel keys. The alarm module is replaceable, so the lock keeps working for years. Batteries are standard button cells that are easy to swap through the locking battery door.
