I understand that, but you can still get the U-lock with the cylinder key style just the same. The thing is that some of the bic style pens are made in different circumferences and some don't work and in that regard are probably better than the traditional key style lock ? The thief has to get the right bic pen size. The traditional key style lock that's a hair pin and a pick tool from being a theft. Some of those videos were 20 seconds of actual time picking the lock. A combination lock pick, that's a visual and audible method that is just as quick as the traditional key. So throw 3 locks on your bike, 2 U-locks and a cable with a combination or traditional key lock and I figure the thief takes 2 minutes if they pause in between the locks ? Sure the thief had to work a little more, but lock a bike up on the apartment patio or a sidewalk bike parking area and it takes a thief no time at all to get a bike with the time available. With a single lock, go into a convenience store and take a little longer to decide whether a soda or sport drink is what you want, then get behind a few customers at the register and the bike is gone when you come out, especially if the thief watches the store for cyclists. It could happen in broad day light. I know that's paranoid, yet possible.
