Bicycle invention ----
Some history books will state that Pierre and Ernest Michaux, the French father and son team of carriage-makers, invented the first bicycle during the 1860s. Historians now disagree and there is evidence that the bicycle is older than that. However, historians do agree that Ernest Michaux did invent the modern bicycle pedal and cranks in 1861.
Baron Karl Drais von Sauerbronn - Early Bicycles
The German Baron Karl Drais von Sauerbronn invented the "Laufmaschine" or "Running Machine", a type of pre-bicycle. The steerable Laufmaschine was made entirely of wood and had no pedals; a rider would push his/her feet against the ground to make the machine go forward. Sauerbronn's bicycle was first exhibited in Paris on April 6, 1818. The celerifere was another similar early bicycle precursor invented in 1790 by Frenchmen, Comte Mede de Sivrac, however, it had no steering.
