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. By the 1860s, pedals were added to the front wheel, but this design was unstable. In 1885, the 'safety bicycle' was introduced with two equal-sized wheels and a chain drive, making it much safer. Interestingly, the rise of bicycles in the 1890s led to improved road surfaces and even influenced women's fashion, as they began wearing more practical clothing for cycling.
