What were the early forms of bicycles?
Since its establishment by the UN in 2018, World Bicycle Day is observed on June 3.
In 1418, an Italian engineer, Giovanni Fontana (or de la Fontana), constructed one of the first known iterations of a wheeled, human-powered vehicle consisting of four wheels and a loop of rope connected by gears.
In 1817, about 400 years after Fontana, a German inventor Karl von Drais debuted his Laufmaschine (running machine), a two-wheeled vehicle, known by many names, including Draisienne, dandy horse and hobby horse.
In the early 1860s a velocipede (fast foot) or a "bone shaker" made of a wooden contraption with two steel wheels, pedals and a fixed gear system, became a popular bicycle form.
In 1885, John Kemp Starley from England introduced the "Rover." With its nearly equal-sized wheels, center pivot steering and differential gears with a chain drive, it was extremely stable, and the first highly practical iteration of the bicycle.
