Good morning, everyone. Today we're going to discuss the history of the bicycle. The first bicycle, invented in the early 19th century, had no pedals and was pushed along by the rider's feet. Later, in the 1860s, pedals were added to the front wheel, but the ride was very bumpy. It wasn't until the 1880s that the chain drive was introduced, allowing the rear wheel to be powered, which made cycling much smoother and safer. This design quickly became popular and is the basis for most modern bicycles.
