Changes

Bicycles, of some types, appears appear as early as Leonardo da Vinci’s sketches from 1493. It is not clear if this device was actualized but indicate concepts that became used later on. By the early 1800s, several types of bicycles were made. Initially, different forms existed. However, among the earliest forms of what would become the forerunner to the modern bicycle was the Draisine (Figure 1), which was a two-wheeled vehicle invented by Karl Drais. This bicycle consisted of front steering and was pushed along by a person's feet, as pedals had not been introduced. The frame of the bicycle is familiar to us, which is what made it different from earlier forms, and gave it an appearance we would recognize. After this development, the next big innovation was the use of pedal. This is not clear when this happened but it could have been invented by Kirkpatrick Macmillan, a Scottish blacksmith. The key design modification though was when Pierre Michaux and Pierre Lallemen put the pedals at the front wheel and put a seat on the support beam in 1863. This now made the bicycle much easier to control and power, enabling the rider to stay stationary while directing the bike.<ref>For more on the early 1800s bicycles and how they developed, see: Herlihy, D. V. (2006).<i> Bicycle: the history</i>. New Haven, Conn.; London: Yale University Press. </ref>

With that innovation, cycling soon began to develop as a recreational activity and sport. In particular, cycle races began to develop by the 1860s. The first documented cycle race of a measured distance was in Paris, which was a 1200 meter event. held in Saint-Cloud Park. Bicycles , some similar to our own forms , now began to appear throughout Europe and North America. In the United States, early bicycle manufacturers were also carriage manufacturers. Riding schools and competitions began to develop by 1869, although in the United States already by then the sport of cycling began to decline due to the fact that early bicycles were often uncomfortable, particularly the seats.<ref>For more on the development cycling as a recreational activity, see: Hutchinson, Michael. <i>Re:Cyclists 200 Years on Two Wheel</i>.
