Introduction
Learning to ride a bicycle is a strong memory from many of our childhoods. Bicycles have been around since the 1800s, although their design has changed from the earliest models. The Draisienne is one of the earliest two-wheeled machines. Made out of wood, it had two wheels of the same size mounted in a frame and handle bars to steer. There were no pedals, so people pushed themselves along with their feet.
The next model to come along was the Velocipede or Boneshaker in the 1860s. It was similar to the Draisienne, however it had pedals added to the front wheel. The wheels were still made of wood, and later metal. This bicycle earned its name "Boneshaker" from the movement riders received when pedaling over the cobblestone roads present during that time.
