The book offered to the attention of readers is a kind of "encyclopedia" of a bicycle, one of the representatives of the detachment of environmentally friendly crews - eco-cars. The popularity of the bike around the world today is huge and growing. Indeed, this ancient vehicle is convenient, useful for human health and harmless to nature, and in the city it is almost as fast as its rival (we hope that they will soon become allies!) - a car. So, you have to make a fascinating journey through the pages of the book on a bicycle - you will start it on an old scooter of the 15th century and end it on an eco-car of the future, only vaguely reminiscent of a bicycle.
