Today we're going to discuss the history of the bicycle. The first two-wheeled vehicle, called the draisine, was invented in 1817 by Karl von Drais. It had no pedals, and riders pushed themselves along with their feet. In the 1860s, pedals were added to the front wheel, creating the 'boneshaker'. Later, in the 1870s, the high-wheel bicycle became popular, but it was dangerous because riders sat high above the ground. The modern safety bicycle, with two equal-sized wheels and a chain drive, was developed in 1885 by John Kemp Starley. This design quickly became the standard we still use today.
