Good morning, everyone. Today we're going to discuss the history of the bicycle. Many people think the bicycle was invented in the 19th century, but its origins actually go back further. In 1817, a German inventor named Karl Drais created a wooden, two-wheeled device called a 'running machine' or 'draisine'. It had no pedals; riders pushed their feet against the ground to move. Later, in the 1860s, pedals were added to the front wheel in France, leading to the 'velocipede'. However, it wasn't until the 1880s that the modern chain-driven bicycle with two equal-sized wheels appeared in England. So, while the basic concept is older, the familiar design we know today is relatively recent.
