The story of the birth of the bicycle is mostly associated with the German baron Karl von Drais,
who joined two carriage wheels to a wooden frame in the early 19th century and added a saddle to the frame. Driving was done by pushing with the feet.
In 1839, Scottish blacksmith Kirkpatrick MacMillan built the first so-called modern bicycle by attaching pedals to the rear wheel. Since riding a bicycle shook the rider hard (hence the name bone shaker), this problem was solved in 1888 by the Scottish veterinarian John Boyd Dunlop, who added inflatable tires to the bicycle. And in 1897, the bicycle got a freewheel mechanism.
