List of motorized trikes is a list of motorized tricycles also called trikes, and are sometimes considered cars. Three main configurations are motorized bicycle with side-car, two wheels in rear one in front, and two in front one in the rear (aka reverse trike). However, language and definitions vary.
One of the most successful trikes of its day was the De Dion-Bouton tricycle; from 1897 until the start of the 20th century about 15,000 copies were sold and was overall the most popular motor vehicle in Europe. Trikes have caused tautological confusion and simply defied typical 2 and 4 wheel classifications, especially in the 21st century; regardless many popular motorcycles and/or automobiles had three wheels.

Whike are sail-powered trikes, which may or may not have be motorized depending if one considers a sail to be a type of motorization.
There is another arrangement of three-wheel, with the wheels in a line; this is so far pretty rare.
Motorcycle with sidecars often end up with three wheels, but there is has been some use of two sidecars (one one each side of a motorcycle, not a sidecar that seats two which is another thing). In one case the use of flexible type sidecars allow the center-line motor bicycle wheels to stay on the ground, and providing adequate handling
