Motorcycle & Bicycle Disc Brake Lock with Alarm, Black

This alarm disc brake lock is a compact anti-theft accessory for motorcycles, electric bikes, and bicycles with compatible disc brakes. It combines a push-down locking pin with a built-in motion alarm to help deter tampering when parked at home, in a garage, or in public areas.

• Built-in alarm is rated by the supplier at 110 dB to help draw attention when the lock is disturbed.
• 6 mm push-down locking pin provides a simple, key-free locking action; keys are used for unlocking.
• Alloy body with sprayed finish helps resist everyday moisture and rust exposure.
• Designed for use on compatible motorcycle, e-bike, and bicycle disc brakes.
• Includes a reminder cord option to help prevent riding away while the lock is still attached.
• Compact size makes it easy to store in a bag, under a seat, or with other riding accessories.
• Source notes indicate two keys are included, giving you one everyday key and one spare.

Choose the color that best matches your bike or is easiest for you to spot. Brighter colors such as red, yellow, green, or blue can be more visible as a reminder that the lock is installed, while black offers a more understated look. The reminder cord option is included and is useful for connecting the lock to the handlebar area so you remember to remove it before riding.

To lock, place the disc lock on a compatible brake disc and press the lock cylinder down until secured. Use the included key to unlock it before riding. Attach the reminder cord between the lock and handlebar area as a visual cue. Check disc clearance before purchase and use, and do not force the lock onto an incompatible rotor. Keep the key spare in a safe place. The included Allen wrench is intended to help access the battery compartment when batteries need replacement.
