Today we're going to discuss the history of the bicycle. The first two-wheeled vehicle, called a velocipede, appeared in the early 19th century. However, it had no pedals; riders pushed their feet along the ground. In the 1860s, pedals were added to the front wheel, but this design was unstable. The famous penny-farthing, with a large front wheel, became popular in the 1870s. It was fast but dangerous because riders sat high above the ground. Finally, in 1885, the 'safety bicycle' was introduced, featuring two equal-sized wheels and a chain drive, making it much safer and more practical for everyday use.
