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 against the ground. In the 1860s, pedals were added to the front wheel, but this design was unstable. Later, the 'penny-farthing' with a large front wheel improved speed but was dangerous. It wasn't until the 1880s that the 'safety bicycle' with two equal-sized wheels and a chain drive became popular, making cycling accessible to the general public, especially women.
