Today we're going to discuss the history of the bicycle. The first bicycle, called the draisine, was invented in Germany in 1817. It had no pedals; riders pushed their feet against the ground. Later, in the 1860s, pedals were added to the front wheel, creating the velocipede. However, this design was uncomfortable due to its rigid frame. It wasn't until the 1880s that the safety bicycle, with two equal-sized wheels and a chain drive, became popular, making cycling accessible to more people, especially women.
