Explanation:
Gears linked by the chain make the machine go faster or make it easier to pedal. Gears are also an example of a simple machine. The force used by pedaling enables the gears of a bike to spin the back wheel. As the back wheel rotates, the tire uses friction to grip the area and move the bike in the desired direction.
