There are two main styles of bike for you to choose from, and these are racing bikes and freestyle bikes. BMX racing requires you to get up to incredibly high speed and if you are serious about competing you will need a BMX bike that has an aluminum frame so that it is lightweight and responsive to your every movement. These kinds of BMX bikes aren't for doing tricks on, but you will find that they are easier to ride around town with if you would like to be able to use your bike in this way as well.
Freestyle bikes are the perfect option if you are interested in learning all about BMX stunts. These bikes are designed to be used for adrenaline-pumping jumps and tricks, and you will be able to use one you buy in your local skate park. They are often made of steel or chromoly, which has a high-end strength to weight ratio. Chromoly-made bikes can usually reach higher speeds and are thought to be easier to maneuver than those made with steel.
