Charles Mochet of France first set out to build a four wheel bicycle, because his wife (just a tad overprotective, are we?) thought that bikes of the day (the 1930s) were way too dangerous for her precious baby boy. So Charles made a little 4 wheeled car that his son could not fall off of. However, he found that the little car was very fast, and son George was leaving the other kids on their bikes in the dust. That observation started Charles on his next project. The first was to make more pedal cars, and there was a mini craze over pedal cars.
From the childs pedal car, Mochet went on to improve a recumbent bike design to a world speed record setting form.
