Good morning, everyone. 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 along the ground. Later, in the 1860s, pedals were added to the front wheel, but this design was unstable. It wasn't until the 1880s that the safety bicycle, with two equal-sized wheels and a chain drive, became popular. Interestingly, the safety bicycle greatly increased the number of women cyclists, as it was easier to ride in long skirts. This had a significant social impact, contributing to the women's suffrage movement.
