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 and was propelled by pushing your feet against the ground. It was called a 'hobby horse'. Later, in the 1860s, pedals were added to the front wheel, leading to the 'penny-farthing' design, which had a very large front wheel for speed. However, this design was dangerous because riders sat very high. By the 1880s, the 'safety bicycle' with two equal-sized wheels and a chain drive became popular, making cycling safer and more accessible to the public.
