So here’s the deal I have done a huge amount of research on bike locks over the last two weeks. What I have concluded is that a U-Lock is best and that the best U-Lock on the market (in my research opinion) is the Kryptonite New York Forgetaboutit. However, it has some draw backs- it is small and it can often be hard to find the right post. Obviously, there is no lock that is cut proof, but I think the Kryptonite is about as good as we can get. What do you guys think?
