In 1887, Félix Théodore Millet (1844-1929) invented a tricycle with a motor consisting of a rotary 5-cylinder star. He then climbs it into the rear wheel of a bicycle in 1893, riding a motorcycle. This is the first multi-cylinder motorcycle.
how about those springy front tires? Wow... and they also had the 5 cylinder rotary engine powering the front tire, rotating around the end of the front forks
