CONVENTIONAL BIKE LOCKS CAN BE CUT IN WELL UNDER A MINUTE
We refuse to ignore the existence of battery operated angle grinders and we won't sell you a lock that can easily be cut by an angle grinder, rebar cutter or bolt cutter without either resisting the cut or punishing the thief for trying to do so.

Finally, bike locks that fight back.

One actively fights back releasing pressurized noxious chemicals, the other passively fights back by resisting angle grinders, rebar cutters and bolt cutters. You choose, or get both for ultimate protection.
