Today's lecture is about the history of the bicycle. The first pedal-powered bicycle was invented in the 1830s by a Scottish blacksmith named Kirkpatrick Macmillan. However, it wasn't until the 1880s that the 'safety bicycle' with two equal-sized wheels became popular, making cycling much safer and more accessible. Interestingly, the introduction of the safety bicycle also influenced women's fashion, as it led to the adoption of more practical clothing. By the early 20th century, bicycles had become a major mode of transport for workers, especially in European cities.
