The term "Safety Bicycle" refers to a type of bicycle that became popular in the late 19th century. Unlike earlier designs, such as the penny-farthing, the safety bicycle features two wheels of equal size, making it more stable and easier to ride. This design allowed for a lower center of gravity, which improved balance and safety for riders. Safety bicycles typically have a chain drive system, which connects the pedals to the rear wheel, enhancing efficiency and control. The introduction of the safety bicycle marked a significant advancement in cycling technology, leading to increased popularity and accessibility for a wider range of people, including women.
