If you live in "Friendly Village", you can get by with a $30 OnGuard Pitbull around the rear wheel, and a locking bolt on the front wheel, or a cheap cable around the front wheel.

But, if you park on a college campus, or in a large American city, you need a "gold" rated u-lock, such as the Kryptonite Fahgettaboudit u-lock, or the OnGuard Brute around the rear wheel and a light u-lock, such as the OnGuard Pitbull around the front wheel.

But, if you are like 90% of the cyclists in my neighborhood, you will use a $20 cable lock, attached only to the frame, or only to the front wheel. I love parking between two bikes locked only with a cable lock. They are an absolute guarantee that no crook will even look at my bike.
