Good morning. Today we're going to discuss the history of the bicycle. As you know, the modern bicycle has two wheels of equal size, but early versions were quite different. The first bicycle, invented in the early 19th century, had no pedals and was pushed along by the rider's feet. Later, the penny-farthing, popular in the 1870s, had a very large front wheel and a small rear wheel. It was difficult to mount and dangerous to ride. Then, in 1885, the safety bicycle was introduced with a chain drive and two equal-sized wheels, making it much more stable. This design quickly became popular.
