Bicycles are simple and beautifully elegant machines that attract just about every kid at an early age. The coolest thing about a bicycle is that it lets you get where you are going a lot faster and using a lot less energy than you would if you were walking or running. The other neat thing about bicycles for anyone interested in machines and mechanics is that everything is completely exposed. There are no covers or sheet metal hiding anything -- on a bicycle, it is all out in the open. Many kids with mechanical tendencies can't resist the desire to take their bike apart!
