Today we're discussing the history of the bicycle. The first pedal-powered bicycle was invented in the 1860s, but it had a major flaw: the pedals were attached directly to the front wheel, making it difficult to steer. In the 1870s, inventors introduced the 'penny-farthing' with a large front wheel and a small rear wheel, which allowed for greater speed but was very unstable. It wasn't until the 1880s that the 'safety bicycle' appeared, featuring two equal-sized wheels and a chain drive. This design made riding much safer and more comfortable, and it quickly became popular among both men and women.
