Good morning, everyone. Today we're going to talk about the history of the bicycle. Now, many people think the bicycle was invented in the 19th century, but in fact, a simple two-wheeled machine appeared in France in the 1790s. It was called a 'velocipede' and had no pedals. Riders pushed their feet against the ground to move. However, it wasn't until 1860s that pedals were added, and later, in 1885, the safety bicycle, which had a chain and equal-sized wheels, became popular. So, the key development that made cycling safe and accessible was the introduction of the chain drive.
