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.
