Experts agree that all bike locks can be broken, so the test of a good lock is whether it is time-consuming and difficult to hack. Reviewers say the Kryptonite New York Fahgettaboudit U-lock is one of the best at repelling attacks -- it holds up longer than other U-locks in tests with hand and power tools. It comes with a $4,500 anti-theft warranty and three flat keys, one of which is lighted. Although it weighs close to 5 pounds, experts say the Kryptonite New York Fahgettaboudit U-lock is a good choice if you live in a high-crime area. Reviewers also like its compact size (3.25 inches by 6 inches on the inside), which means less room for thieves to gain leverage, but it might be a little small for bikes with a beefy frame and thick wheels. If you don't want to carry around a second lock to secure the wheels, another option is the longer (though slightly less thick) Kryptonite New York STD U-lock (*Est. $60) , which many reviewers prefer over the Fahgettaboudit for its size.
