Heavy Duty Waterproof Disc Brake Lock
Park It. Lock the Disc. Make Movement Harder to Ignore.
Add a compact physical barrier and a movement-triggered audible warning to your motorcycle, scooter or compatible e-bike whenever you park and walk away.

A Silent Lock Can Only Do Half the Talking.
A mechanical lock creates an obstacle, but it cannot call attention to unexpected movement. This disc lock adds an audible response while keeping the whole setup compact enough for everyday stops.
A conventional mechanical lock cannot create an audible warning when the bike is disturbed.
Large chains can be inconvenient when you only want an extra security layer for everyday parking.
Coffee runs, errands and work parking are exactly when fast setup matters.
It Doesn't Just Sit There Quietly.
An integrated vibration-sensitive alarm is designed to respond when the installed lock or wheel is disturbed, adding an audible warning alongside the physical locking pin.
Designed to react to disturbance around the locked wheel.
Adds a loud audible warning rather than relying only on silent mechanical resistance.
The alarm complements the disc-mounted locking pin instead of replacing it.
Press to Lock. Use the Key When You Return.
Once the locking pin is positioned through a compatible brake-disc opening, the push-down cylinder lets you engage the lock without fumbling with the key during installation.
The Sound Gets Attention. The Pin Still Blocks Wheel Rotation.
The compact alloy body sits around the brake rotor while an approximately 6mm locking pin passes through a compatible opening, creating a physical restriction against normal wheel movement.
Designed for a compatible brake-disc opening larger than the locking pin.
Compact metal construction designed around everyday motorcycle parking use.
Small enough to carry in riding gear or an onboard storage compartment.
One Small Measurement Makes the Difference.
Disc-lock fit depends on your brake rotor. Check for a suitable opening before ordering rather than assuming every rotor uses the same layout.
> 6mm
Suitable Brake-Disc Opening RequiredThe locking pin is approximately 6mm / 0.24 in thick. Choose an opening that gives the pin enough clearance to pass through without forcing it.
Remember the Lock Before You Twist the Throttle.
A disc lock prevents normal wheel movement, which means forgetting it before riding can damage the motorcycle. Use the included reminder cord every time you install the lock.
Route the reminder cord toward the handlebar so the installed lock stays in your line of sight.
Unlock and completely remove the device from the rotor before moving the vehicle.
Keep the lock and its accessories together when they are not installed.
Useful Wherever You Regularly Park and Walk Away.
Black, Red or Blue.
Go discreet with black or choose a brighter finish that is easier to notice on the wheel.

Small Enough to Carry. Quick Enough to Actually Use.
Movement sensing adds sound to a security setup that would otherwise stay silent.
The locking pin passes through a compatible disc opening to restrict normal wheel rotation.
Quick engagement makes it easier to add the lock to short everyday parking stops.
Designed for ordinary outdoor parking and rain exposure, without claiming submersible protection.

Use It as One Layer of Your Parking Security.
Portable locks can add obstacles and deterrence, but no compact lock can guarantee that a vehicle will never be stolen. Parking choices and layered security still matter.
Frequently Asked Questions
What happens when the lock is disturbed?
The integrated vibration-sensitive alarm is designed to respond to movement around the installed lock. The product lists a rated alarm output of 110dB.
Do I need the key to lock it?
The push-down cylinder allows you to engage the lock by pressing it into position. The supplied key is used to unlock and remove it.
How do I know whether it fits my motorcycle?
Inspect your brake rotor before ordering. The lock uses an approximately 6mm pin, so the intended rotor opening needs to be larger than 6mm and positioned where the lock body can sit correctly.
Is it fully waterproof?
It is designed for normal outdoor parking and rain exposure. Do not intentionally submerge the lock or leave it underwater for extended periods.
Why is a reminder cord included?
It provides a visible cue at the handlebar that the disc lock is still installed, helping remind you to remove it before moving the vehicle.
Can this guarantee my motorcycle will not be stolen?
No portable security product can provide that guarantee. This lock is intended to add a physical obstacle and an audible deterrent layer to sensible parking and other appropriate security measures.
Is it bulky to carry?
The product is approximately 80 Γ 36 Γ 50mm and weighs about 185g / 6.53 oz, making it considerably more compact than a large chain-style lock.
