When wandering the streets of Copenhagen, you can quickly see that they have a different way to lock their bikes than we do here in New Zealand. Over there, in one of the cycling capitals of the world, the lock of choice is a frame lock, a lock that is permanently attached to the frame of the bike, and locks through the back wheel. One of the top producers of frame locks is AXA. Plus, they make some great looking lights, with top quality LED bulbs!!
