The document traces the history of the bicycle from 1817 to present day. It shows the early prototypes like the Draisienne and Velocipede that led to the high wheel bicycle popular in the late 1800s. The safety bicycle design with equal sized wheels, chain drive, and pneumatic tires emerged in the 1880s making cycling more accessible. Bicycles grew rapidly in popularity in the late 1800s but declined with the rise of automobiles in the 1920s when they became seen as children's toys. Different styles of bicycles then emerged through the 1900s for various uses like racing, mountain biking, BMX, and cargo/utility bicycles. Hybrid and electric folding bikes gained popularity in recent decades.
