If you are riding a $50 bike, it probably doesn't make sense to buy expensive locks. But, if you have a $500 bike that will be "unattended" in a large city or on a college campus, you need TWO serious locks. Get a good chain lock, such as the Kryptonite Fahgettaboudit or the OnGuard Beast 5016 chain, and a good U-lock, such as the Kryptonite New York lock, or the OnGuard Brute 5001 U-lock. The combination of those two sorts of locks will send a crook to the next bike on the rack...the one with the cable lock, or the Wal-Mart U-lock. Of course, two such locks will weigh as much as your bike...but...
