One day while browsing in a nearby LBS, I noticed that a slightly different type of U-lock was for sale. The U-lock in itself was basically the same except that it was much smaller than older ones that I own. Attached to each lock was a long chain that can't be found in the average hardware store.
With all that I've heard which states that U-locks don't work, what will make this one different and better? Can the lock still be picked with a Bic pen? Can the chain be cut?
