Hexlox is intended to make life difficult for bicycle and opportunistic thieves.
What looks like a simple screw is actually a small magnet that cannot be removed without a suitable key. You simply attach the Hexlox to the screws, wheels and saddle on the bike and they are safe from theft.
Thanks to a personal code, the Hexlox can only be attached and removed with the appropriate key. Neither magnet, pliers nor glue can remove the screw from its place.
