The bicycle is still popular. In some countries, people use bicycles because they are the cheapest way to getting around. In some another countries, people use them mainly because they prefer this form of transport than any other.

It is said that when a German inventor created the first bicycle in 1816. It was two-wheeled and moved along by push of the rider's feet upon the ground. This vehicle was improving in 1839 by a Scottish blacksmith, which invented pedals(踏板). Eventually, bicycles are also made specially for women. They had big rear wheels than front wheels, and riders could sit more upright. Nowadays, women’s bicycles have changed again to become more usefully to those involved in sports.
