Product Description

The Best Alarm System for Your Bicycle

A regular lock is okay, but a lock with a powerful alarm system is far superior. The 440A padlock, boasting 100 decibels, will send any thief running for the hills. We use alarm systems to safeguard our most precious belongings, so why not our bikes? The 440A Alarm padlock comes with a proven 3D Position Detection System that can detect even the slightest movement. If a thief tries to mess with your bike, the lock will immediately sound a deafening alarm. At 100 decibels, as loud as a circular saw, it can be heard from a great distance. Such a powerful alarm is sure to scare off any bike thief.

Technology

  • 12 mm hardened round shackle
  • The shackle, body, and load - bearing parts of the locking mechanism are made of specially hardened steel
  • The modern and unique design of the lock body casing ensures easy handling
  • High - quality locking cylinder offers excellent protection against picking and other forms of manipulation
  • An alarm at a volume of at least 100 dB for 15 seconds, followed by automatic reactivation
  • 3D Position Detection: Detects vibrations and the smallest movements in all three dimensions and triggers an alarm
  • Comes with CR2 batteries

Using this 440A Keyed Bicycle U - Lock with Alarm is a breeze. First, make sure you have the included CR2 batteries installed. Then, find a sturdy object to lock your bike to, like a bike rack. Pass the shackle through your bike's frame and the object, and then lock it using the key. When the lock is in place, the 3D Position Detection System will start working. If anyone tries to move your bike, the alarm will go off. As for maintenance, keep the lock clean and dry. Avoid exposing it to extreme temperatures. If the alarm doesn't sound as loud as it should, check the batteries and replace them if needed. And always keep your key in a safe place so you don't lose it.
