Bicycles are simple and beautifully elegant machines that attract just about every kid at an early age, working their way up from tricycles and training wheels.
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 if you were walking or running.
Another 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 any of the working parts that propel you down the road -- on a bicycle, it is all out in the open. Many kids with mechanical tendencies can't resist the desire to break out the tool set and take their bike apart!
