| The illustration shows a two wheeled bicycle which is a relatively recent invention. Describe to someone with no prior knowledge how a bicycle operates. |
Example
In general, riding bicycles is a remarkable yet straightforward process that requires little prior knowledge.
The most well-known component of a bicycle, the saddle, also known as a seat, is one of three points of contact on an upright bicycle. It’s a spot where you sit on your bike while riding. A bicycle saddle is often attached to the bicycle frame, which is the bicycle’s principal component and onto which wheels and other components are mounted.
The second point of contact on a bicycle is a pedal, which is the portion of the bike that you push with your foot to propel it forward. The pedal is responsible for connecting the cyclist’s foot or shoe to the crank arm which propels the bicycle wheel by turning the chain. The cog-set is a black circular feature in the center of the back wheel that serves as a speed transmission device.
The bicycle's handlebar, or steering mechanism, is its final point of contact. You place your hands on the handlebars and control the bicycle by turning them in different directions. The handlebars are connected to the stem, which descends and attaches to the fork—a thin metal rod that connects the front wheel to the bicycle's frame.Glossary
