A safety bicycle is a type of bicycle that was developed in the late 19th century, designed to be more stable and easier to ride than earlier models. It features two equal-sized wheels, unlike older bicycles with a large front wheel and a small rear wheel. The design includes a chain-driven mechanism, which allows the rider to pedal directly to propel the bike forward, providing a smoother and safer ride. The safety bicycle is considered the predecessor to the modern bicycle and made cycling more accessible to the general public by offering better balance and control.
