Today we're going to discuss the history of the bicycle. Now, most people think the bicycle was invented in the 19th century, but its origins go back further. The first two-wheeled vehicle, called a 'velocipede', appeared in France in the 1790s. However, it had no pedals; riders pushed their feet against the ground. It wasn't until 1860s that pedals were added to the front wheel, creating the 'boneshaker'. Later, in the 1880s, the 'safety bicycle' with a chain drive and equal-sized wheels became popular, making cycling much safer and more comfortable. This design is the basis for modern bicycles.
