110dB Motorcycle Disc Brake Alarm Lock – 6mm Pin
Add A Visible, Audible Layer Of Security To A Parked Motorcycle Or E-Bike
A compact disc-brake lock combines a mechanical locking pin with a vibration-triggered 110dB alarm to help deter tampering while your vehicle is parked.

A Disc Lock Works Where A Thief Can See — And Hear — It
The lock attaches directly through a compatible brake-disc opening. If the parked vehicle is disturbed, the sensor is designed to trigger the alarm while the mechanical lock remains engaged.
110dB Alarm
The supplied specification lists a 110dB alarm intended to draw attention when movement or vibration is detected.
Push-Down Locking
Press the lock cylinder down to secure a compatible brake disc without needing the key for the locking step.
Reminder Cord
Use the included safety cord as a visual reminder to remove the lock before riding.

Check The Brake-Disc Hole Before Ordering
The source states that the vehicle's disc-brake opening should be larger than 6mm / 0.24 in for compatibility.

Use The Alarm As A Deterrent — Not A Theft Guarantee
A compact disc lock can add friction and noise to an attempted theft, but no portable lock can make a vehicle theft-proof.

Made For Compatible Disc-Brake Vehicles
Use only where the locking pin can pass through the brake disc without contacting or damaging nearby components.

Rain-Resistant For Normal Outdoor Parking
The source describes weather seals and also specifically advises against prolonged water submersion, so the product is presented here as rain-resistant rather than fully submersible.

Frequently Asked Questions
Will it fit every motorcycle?
No. The source says the brake-disc opening should be larger than 6mm / 0.24 in, and surrounding clearance also needs to be sufficient.
Do I need the key to lock it?
The source describes a push-down mechanism that allows the lock cylinder to be pressed into the locked position. Keep the key with you for unlocking.
Is it waterproof?
The source uses waterproof language but also warns against prolonged submersion. This page therefore describes it more conservatively as suitable for normal rain exposure when used as directed.
Does it guarantee the motorcycle cannot be stolen?
No. It is a security deterrent and mechanical lock, not a guarantee against theft.
