Good morning, everyone. Today we're going to discuss the history of the bicycle. Now, many people think the bicycle was invented in the 19th century, but its earliest form dates back to the 18th century in France. However, the first practical bicycle with pedals was developed in Scotland in 1839 by a blacksmith named Kirkpatrick MacMillan. Interestingly, it wasn't until the 1880s that the chain drive and pneumatic tires were introduced, which made cycling much more comfortable and efficient. By the early 20th century, bicycles had become a popular mode of transport for ordinary people, especially in European cities, before the rise of motor vehicles.
