Good morning, class. Today we're going to discuss the history of the bicycle. The first bicycle, invented in the early 19th century, had no pedals. Riders pushed their feet against the ground to move forward. Later, in the 1860s, pedals were added to the front wheel, which made riding faster but also more dangerous. By the 1880s, the 'safety bicycle' with two equal-sized wheels and a chain drive became popular, as it was much more stable. Interestingly, the rise of the safety bicycle also influenced women's fashion, as it encouraged the wearing of more practical clothing.
