Today we're going to discuss the history of the bicycle. Surprisingly, the first bicycle, invented in the early 19th century, had no pedals. It was called a 'hobby horse' and was pushed along by the rider's feet. Later, in the 1860s, pedals were added to the front wheel. This design was known as the 'boneshaker' due to its uncomfortable ride. The real breakthrough came in 1885 with the 'safety bicycle', which had a chain drive and two equal-sized wheels. This made cycling much safer and more practical, leading to a boom in popularity among the general public.
