Good morning, everyone. Today we're going to discuss the history of the bicycle. You might think it's a simple invention, but its development took over a century. The first two-wheeled vehicle, called a draisine, appeared in 1817. It had no pedals; riders pushed their feet against the ground. Then, in the 1860s, pedals were added to the front wheel. However, these early bicycles were uncomfortable and hard to ride. The real breakthrough came in 1885 with the 'safety bicycle', which had a chain drive and two equal-sized wheels. This design made cycling much safer and more popular, especially among women, as it allowed them to wear ordinary clothes.
