This animation demonstrates the rotation of the front and rear cogs of a
bicycle. Notice that for each turn of the larger front cog the rear cog turns
twice. The animation also produces an interesting optical illusion where the
"spokes" on the front cog appear to be moving backward. |

The development of the chain drive helped make the bicycle that we know today possible. The chain drive eliminated the need to have the cyclist directly above the wheel. Instead the cyclist could be positioned between the two wheels for better balance. With the advent of gears, the cyclist could also pedal more efficiently. Riders enjoyed increased speed and easier riding up steep grades. | |||
