Today we're going to discuss the history of the bicycle. Although many people credit the invention to the 19th century, early prototypes appeared as far back as the 18th century. However, the first practical model, the 'velocipede', was introduced in the 1860s in France. It had pedals attached to the front wheel, which made it difficult to ride on rough roads. Later, in the 1880s, the 'safety bicycle' was developed in England, featuring a chain drive and two equal-sized wheels, making it much more stable. This design became the basis for modern bicycles.
