Today we're going to discuss the history of the bicycle. The first two-wheeled vehicle, called the draisine, was invented in 1817 by a German baron. It had no pedals; riders pushed their feet against the ground. Later, in the 1860s, pedals were added to the front wheel in France. This design, known as the velocipede, was popular but uncomfortable due to its rigid frame. The major breakthrough came in 1885 when the safety bicycle was introduced, featuring a chain drive and two equal-sized wheels, making it much safer and faster than previous models.
