Immobilizers are finally coming to prevent bicycle theft

The bike lock works as an immobilizer and simply locks the pedals in a fixed position leaving the bike useless when locked. On e-bikes, it furthermore connects to the whole electrical system, which completely disables the e-bike’s motor, display, etc. when locked.   The PentaLock immobilizer is a vital part of the bike and can easily be integrated into existing bike models.

Integrated smart alarm and pas sensor

Integrated into the bike, the lock is impossible to remove and practically unbreakable. It locks automatically after 30 seconds, which means that the user will never forget to lock the bike. Furthermore, the bike is secured by an effective bike alarm system, which would scare any thief away. The lock replaces the existing bottom bracket and comes fully equipped with a PAS sensor.

With a little help from a former thief

When inventing the lock, founders involved both a former professional thief and an insurance company in the design process. Realizing the value of making the bike useless for good without the key and the unwanted attention from an alarm, they got the pillars to create the most innovative and secure bicycle lock ever.
