History of bike’s invention

Слайд 2The bicycle has a very interesting inner history of invention which

started long time ago. They say that Leonardo da Vinchy was the first to invent a bicycle. There are no facts in proof of this claim but taking into account all his developments it is easy to believe that it could have been his invention.

The bicycle has a very interesting inner history of invention which started long time ago. They say

Слайд 3But one thing is to suppose, the other thing is to

have some facts. People have been using the bicycle for 200 years! A real history started with the invention of German Baron Karl von Drais. He presented his wooden “Draisienne” in about 1818.

was Fred A. Birchmore. He crossed Europe, Asia, the United States having covered the distance of 40 000 miles. It is difficult to imagine the number of tires he used! I believe that it was the best year of his life. And what about the most famous bicycle race “Tour de France”? It was the year of 1903 when it started for the first time. From the time the bicycle was invented and up to the present moment it has become not only the vehicle but the style of life.
