Good morning, everyone. Today we're going to discuss the history of the bicycle. One key figure is Karl von Drais, who invented the 'running machine' in 1817. This early bicycle had no pedals; riders pushed their feet against the ground. Later, in the 1860s, pedals were added to the front wheel, creating the 'boneshaker'. However, it was not until the 1880s that the 'safety bicycle' with a chain drive and two equal-sized wheels became popular, making cycling much safer and more accessible to the general public.
