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 pushed along by the rider's feet. 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 and difficult to ride. It wasn't until the 1880s that the 'safety bicycle' was introduced, with a chain drive and two equal-sized wheels, which made cycling much safer and more popular. This design is the basis for modern bicycles.
