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 the rider's feet pushing against the ground. It was called a 'hobby horse'. Later, in the 1860s, pedals were added to the front wheel, creating the 'velocipede'. However, this design was uncomfortable due to its rigid frame and wooden wheels. By the 1880s, the 'safety bicycle' was introduced with a chain drive and two equal-sized wheels, which made riding much safer and more efficient. This design quickly became popular and remains the basis for modern bicycles.
