Dreis was a forester, and every day he went from one forest to the other.
The hard work of walking for years inspired him to invent a means of transportation.
He thought: If people sit on wheels, they can go faster!
In this way, Dreis began to design and manufacture of bicycle.
He made a wheelbarrow with two wooden wheels, a saddle, and a handlebar that control the front wheels.
People sit on the bike and drive the wooden wheels with their feet.
That＇s it. The first bicycle in the world came out.
Tom saw an advertisement in a newspaper for a beautiful modern bicycle which cost £50, so he went to the shop to have a look.
After examining the bicycle carefully, Tom turned to the shopkeeper and said, "There isn't a lamp on this bicycle, but there was one on the bicycle in your advertisement." "Yes, sir," answered the shopkeeper, "but the lamp isn't included in the price of the bicycle. It's an extra."
"Not included in the price of bicycle?" Tom said angrily, "But that's not honest. If the lamp's in the advertisement, it should have been included in the price you gave there."
"Well, sir," answered the shopkeeper calmly, "there is also a girl on the bicycle in our advertisement, shall we supply one for you too?"
