1790
The first contraption that can realistically be said resembles a bicycle was constructed around 1790 by Comte Mede de Sivrac of France. Called a celerifere, it was a wooden scooter-like device with no pedals or steering. A similar model, improved with a steering mechanism attached to the front wheel, was created in 1816 by German Baron Karl von Drais de Sauerbrun. He called it a Draisienne, after himself, though popular parlance also dubbed it the hobby horse.
