To the unfamilair it may seem like a simple wheel with some teeth, but for me it's the world's greatest invention. This 'simple' invention is used today in tons of other way more complicated mechanic objects. For example your bike, your car and movie projectors (the older ones).

It is the foundation of modern ground transportation

In bicycles the gear is used as a gear ratio. This is done by moving the chain over sprockets with different diameters. This results in an optimal solution for a topographic varying terrain.
