Good morning, everyone. Today, I'd like to discuss the history of the bicycle. While many people credit the invention to the French in the 19th century, the first two-wheeled vehicle, called the draisine, was actually created by a German baron in 1817. It had no pedals; riders pushed their feet against the ground. Later, in the 1860s, pedals were added to the front wheel in France, leading to the penny-farthing. However, it was not until the 1880s that the chain-driven 'safety bicycle' with two equal-sized wheels became popular, making cycling much safer and more accessible to the general public.
