Best bicycle locks

This is a great article about the best bicycle locks that this guy can find. He buys a bunch of different cable locks, U-locks and chains. (Sometime U-locks are called D-locks but I think it's the same thing)

He then pursues to lock up his bike and then tries to break the lock with a set of different hand tools such as hacksaw, bolt cutters, crowbar etc. Every lock is judged by security, ease of use and value in price but security is a 20 point scale whereas ease of use and value is a 10 point scale.

I like this article because A) I can learn something about what lock to buy for my bike and B) it's nice to see when someone puts his efforts in to put together a nice little article like this.

Thank you Scott Elder for the review!
