Michaux-Perreaux steam velocipede
L. J. K. Setright and David Burgess-Wise say that it was Pierre Michaux's son Ernest who first attached the engine to the velocipede. Charles M. Falco says it was Louis-Guillaume Perreaux. The Michaux-Perreaux machine was made out of one of the first pedal bicycles that sold well, a boneshaker. Michaux had been building over 400 of these bicycles per year since 1863. The velocipede also used a single cylinder alcohol fueled Perreaux engine, which used twin flexible leather belt drives to the rear wheel. They put a steam pressure gauge where the rider could see it, above the front wheel. They added a hand control so the rider could control the steam. The base Michaux velocipede came with a spoon brake, but the steam version had no brakes. The engine weighed , and the whole steam velocipede weighed . In a June 14, 1871 version, Perreaux removed some cranks and pedals from the front wheel. There was an arched downtube instead of straight one to give the engine more space. The steam velocipede worked. It did not have any commercial successors.
