The LINKA Auto-Unlocking Smart Bike Lock ensures your bicycle remains locked up better than before. Featuring tamper alerts and a built-in siren, this gadget helps you know your bike’s whereabouts at all times. In fact, the 100-decibel siren ensures anyone nearby looks at anyone trying to steal your bicycle. Plus, it even offers an auto-unlock feature to make access easy.

With its sophisticated triple-axis accelerometer, it reduces the chances of false alarms by recognizing the methods and movements of thieves. So it won’t go off when someone bumps your bicycle on accident.
