Today we're going to discuss the history of the bicycle. Many people assume the bicycle was invented in the 19th century, but its origins actually go back further. The first two-wheeled vehicle, called a draisine, appeared in 1817 in Germany. It had no pedals; riders pushed their feet against the ground. Later, in the 1860s, pedals were added to the front wheel in France. However, these early bicycles were difficult to ride because the front wheel was much larger than the rear. It wasn't until the 1880s that the 'safety bicycle' with equal-sized wheels and a chain drive became popular, making cycling safer and more accessible to the general public.
