Today we're going to discuss the history of the bicycle. While many people assume the bicycle was invented in the 19th century, its origins actually go back further. The first two-wheeled vehicle, called a draisine, was created in 1817 by a German inventor. However, it had no pedals; riders pushed their feet against the ground. Later, in the 1860s, pedals were added to the front wheel, leading to the 'penny-farthing' design with a huge front wheel. This was efficient but dangerous. Finally, in 1885, the 'safety bicycle' with a chain drive and two equal-sized wheels became popular, making cycling accessible to the general public.
