The 'hobby horse' is one of the earliest forms of bicycle and is believed to have been developed by Karl von Drais, Baron of Sauerbrom in 1816. It is claimed that it was so called because the Baron spent so much money on this hobby that he couldn't afford a horse. The hobby horse, or the 'Draisine' as it became known, didn't have pedals and so the rider used their legs to propel the bicycle forward.
