Motorcycle Disc Brake Alarm Lock – Scooter & Bicycle Security

$38.62 $48.42

Universal Disc Brake Alarm Lock for Motorcycles, Scooters & Bicycles

Keep your motorcycle, scooter, or bicycle secure with this compact yet powerful alarm disc brake lock. Engineered for universal compatibility, it clamps directly onto your disc brake rotor to immobilize your ride instantly — all while featuring a built-in vibration alarm that sounds off the moment anyone tampers with your vehicle.

How It Works

Simply press the lock core into the disc brake — you'll hear a single "DU" beep confirming the lock is armed and in standby mode. After 5 seconds, the vibration sensor activates. Any movement or shock triggers a loud three-beep alarm ("DU DU DU"). Repeated vibrations cause the alarm to sound continuously for up to 10 seconds per cycle, deterring would-be thieves effectively.

Includes Reminder Rope: Attach the reminder rope to your handlebars so you never accidentally ride off with the lock engaged.
Made in Mainland China.

Battery Replacement

When you hear a continuous "Ge, Ge, Ge" sound or the alarm cuts off in under 10 seconds, it's time to replace the batteries. Use the included spanner to remove the four screws, lift the top cover, and replace the batteries — paying attention to correct polarity (+ and -).

Frequently Asked Questions

Q: Is this disc brake alarm lock compatible with my motorcycle or bicycle?

A: Yes — this is a universal disc brake lock designed to fit most motorcycles, scooters, and bicycles equipped with standard disc brake rotors. Simply ensure the rotor has a hole large enough for the lock pin to pass through.

Q: How loud is the alarm, and will it deter thieves effectively?

A: The built-in vibration alarm emits a loud audible alert that triggers with any movement or shock. It cycles for up to 10 seconds per vibration event and repeats with continued movement, making it an effective deterrent in public spaces.

Q: What type of batteries does this lock use, and how long do they last?

A: The lock comes with 6 batteries included in the package. Battery life varies depending on alarm frequency. When the battery is running low, the lock will emit a distinct "Ge, Ge, Ge" chirp as a warning signal so you can replace them before they run out entirely.

Q: What happens if I forget the lock is engaged and try to ride away?

A: The included reminder rope attaches from the lock to your handlebars as a visible and physical reminder. This prevents accidental riding with the lock still engaged on the disc brake.
