In today's lecture, we'll discuss the history of the bicycle. The earliest bicycles, called 'hobby horses,' appeared in the early 19th century and were pushed along by the rider's feet. Then came the 'penny-farthing' in the 1870s, known for its large front wheel. However, it was dangerous because riders sat high above the ground. The modern safety bicycle, with two equal-sized wheels and a chain drive, was developed in the 1880s. This design made cycling much safer and more accessible to the general public.
