1868 Michaux-Perreaux steam powered

In 1868, the French engineer Louis-Guillaume Perreaux patented a steam-powered vehicle, These steam-powered vehicles were invented prior to the first petroleum-powered motorcycle.
By 1868 Michaux of Paris were already established as the largest bicycle manufacturer in Europe. Small industrial steam engine had become commercially available in France and Pierre Michaux decided to install a complete steam power plant, which he obtained from Perreaux, within the framework of one of his ‘boneshaker’ bicycles.

The rider started the cycle by foot pedals on the front wheel, and once forward motion was established pressurized steam was admitted to the cylinder. Transmission was by two leather belts direct from an engine pulley to each side of the rear wheel. The machine had no brakes, iron tyres, and was reputedly capable of 10 mph.
