James Roots

James Roots made a light tricycle in 1892.

It was capable of 15 mph and the engine was a single-cylinder two-stroke operating on the 'Day' cycle, with crankcase compression. It was water-cooled and hung upside-down behind the rear axle, which it drove by bevel gears. The frame tubes circulated the the cooling water and it had a single front wheel.

Although the De Dion-Bouton tricycle was more famous, this pre-dated it.
