When looking at BMX bikes, there are many important decisions to be made. How much money do I want to spend? What is more important: a lightweight bike or a durable one? Do I want to ride mostly on the streets or in the dirt? Knowing the answers to these questions can lead to you finding your perfect bike.
There are three styles of BMX bikes: classic BMX, jump bikes and freestyle BMX. What you will be doing with your bike gives you a good idea of which is right for you. If you intend to ride mostly on asphalt, choose the classic BMX (although it is dirt ready if you want to hit the track) or the freestyle BMX (sturdier, and equipped with road tires). Jump bikes are great if you want to ride on ramps, and freestyle bikes are perfect for trick cycling on the street, in the dirt and at a skate park. Freestyle bikes are built the sturdiest of all BMX bikes, so they come out of the shop ready to take a beating.
What type of frame is right for you? Steel (Chromoly) frames are cheaper and sturdier, so they make sense for trick bikes- if you intend to beat up your bike, best to buy one with an affordable replacement cost. Aluminum frames are lightweight, so they are more convenient for casual or street riders. The benefit of an aluminum frame for ramp and jump riding is that their lightness makes the frame easier to lift. Another benefit of aluminum frames is that they do not rust as quickly as steel frames.
Once you have these important differences sorted out, you need to decide on rims and breaks. Each bike has a style of rim generally associated with it, though you can deter from these standards: Freestyle bikes have mag or 48-spoke rims. Jumpers need strong rims, so they generally come with 48-spoke or 36 ultra-heavy-duty 13 gauge spokes. Classic BMX bikes come with 32-spoke rims.
BMX and jump bikes have rear brakes; freestyle bikes have front and rear. Although they can be tailor to your liking, these standards are generally followed, as they are what's most logical for the styles of riding the bikes are designed for.
