Read the text. Bicycles have evolved over many years. In 1818, a heavy two-wheeled device called a
"velocipede" was patented in Paris. The rider controlled the direction with a steering
wheel and moved it forward by pushing his feet on the ground. It caught on briefly, and
many people worked to refine its design. In 1863, pedals were added. A few years later,
a new, lighter bike was developed that used a very large front wheel and a small rear
wheel. Called the "Ariel," it became popular but was quite accident-prone. Over the next
decade, "safety" bicycles were produced, incorporating welcome improvements such as
air-filled rubber tires, brakes, and gears. By 1899, about a million bicycles were in use.
