Good morning. Today we're going to discuss the history of the bicycle, focusing on its impact on society. The first major change came in the 1860s with the invention of the pedal, which allowed riders to move without touching the ground. However, it wasn't until the 1880s that the 'safety bicycle' with two equal-sized wheels became popular, making it much safer and easier to ride. This led to a boom in cycling, especially among women, as it provided them with a new sense of freedom and independence. By the early 1900s, bicycles were also used for delivery services and even in the military for message carrying.
