Good morning, everyone. Today we're going to look at the history of the bicycle. Now, you might think the bicycle is a fairly modern invention, but in fact, the first two-wheeled vehicle, called a 'draisine', was invented in 1817 by a German baron. It had no pedals; you pushed it along with your feet. Then, in the 1860s, pedals were added to the front wheel in France. However, these early bicycles were very uncomfortable because of the solid rubber tires and rough roads. It wasn't until the 1880s that the modern 'safety bicycle' with a chain drive and two equal-sized wheels appeared, making cycling much safer and more popular.
