Disc Brake Lock Alarm With Motion Sensor and USB C Rechargeable Battery for Motorcycle Security

Walking away from your parked bike never feels completely settled. You second guess the spot and spend the whole errand worrying about it. Lock it down for a quick errand, a full day out, or an overnight stay.

Clip it onto your brake disc and a beep confirms it is armed. A motion sensor detects any shift and fires a 120 decibel alarm immediately. After five seconds it arms on its own without any extra steps from you.

Aluminum alloy and zinc construction holds up against cutting and forced entry attempts. One USB C charge powers the lithium battery through up to six months of standby. A 0.27 inch hardened pin fits brake discs up to 2.4 inches wide.

IP67 water resistance means rain and wet conditions won't affect performance at all. At 10 ounces it fits neatly into a storage compartment between rides. Two keys, a charging cable, and a five foot reminder cable come included.

• INSTANT BEEP CONFIRMATION ON ARMING: Clips onto the brake disc and a beep sounds immediately to confirm the lock is armed and active without any guesswork on your part.
  
  
• 120 DECIBEL MOTION TRIGGERED ALARM: Built in motion sensor detects any shift or movement and fires a 120 decibel alarm immediately to draw attention and deter anyone attempting to move the bike.
  
  
• AUTO ARM AFTER FIVE SECONDS: Arms itself automatically five seconds after being clipped on so there are no extra steps or button presses needed before you walk away.
  
  
• ALUMINUM ALLOY AND ZINC CONSTRUCTION: Heavy duty material combination resists cutting tools and forced entry attempts to hold up against determined theft in unsupervised locations.
  
  
• USB C RECHARGEABLE LITHIUM BATTERY: Single USB C charge powers the battery through up to six months of standby so you are not constantly reaching for a cable between uses.
  
  
• 0.27 INCH HARDENED PIN FOR WIDE COMPATIBILITY: Hardened pin measures 0.27 inches and fits brake discs up to 2.4 inches wide to cover a broad range of motorcycle models without adapters.
  
  
• IP67 WATERPROOF RATING: Fully sealed against rain and wet conditions so performance stays consistent whether the bike is parked outdoors overnight or through a full day of weather.
  
  
• COMPACT AND STORAGE FRIENDLY: Weighs just 10 ounces and fits neatly into a motorcycle storage compartment so it travels with the bike without taking up meaningful space between rides.

Frequently Asked Questions

How do I know the lock is armed after clipping it on?
A beep sounds immediately after you clip it onto the brake disc to confirm it is armed, and it arms itself automatically after five seconds without any additional steps needed from you.

Will it go off from light vibrations like passing traffic?
The motion sensor is calibrated to detect meaningful shifts and movement rather than minor environmental vibrations, so it triggers on actual disturbance rather than routine street activity.

How long does a single charge last?
One USB C charge powers the lithium battery through up to six months of standby so you can go extended periods between charges without worrying about it going dead while parked.

Can it stay on the bike in the rain?
Yes, the IP67 water resistance rating means it handles rain and wet outdoor conditions without any impact on performance, making it suitable for overnight and extended outdoor parking.
