In 1885, a germany engineer was named Gottlieb Daimler composed a combustion engine of his own design to be a vehicle covered by a wood. The vehicle has 4 wheels, included two round wheels for stability (more similiar to excercise wheels), which techically does not make it included into a bicycle. But, historians assume Daimler's vehicle as the first motorcycle in the world.
The son of Daimler, Paul, became the first rider on November 10th, 1885, when he rode the discovery of his father and reached almost 10 km (6 miles).
