Good morning, class. Today we're discussing the history of the bicycle. The first two-wheeled vehicle, called a 'draisine,' was invented in 1817 by a German baron. It had no pedals; riders pushed their feet against the ground. In the 1860s, pedals were added to the front wheel in France, creating the 'velocipede.' Later, the high-wheel bicycle became popular in the 1870s, but it was dangerous because riders sat very high. Finally, in 1885, the 'safety bicycle' was introduced with a chain drive and equal-sized wheels, making riding much safer and more practical.
