I am confident that my Kryptonite NY U-lock will stop 95% of thieves in my city. I am able to pick many locks (hobby of mine) but I'm unable to pick my U-lock. Of course, the pros use those angle grinders or chain saws to cut through the lock. If I was a bike thief I would dress just like that guy. You can fit into the downtown area M-F 9AM-5PM very easily. Did you happen to ask him what bikes they target and what locks are the hardest to get through?
