Alternatively, a more conventional front-engine, front wheel drive layout as is common in four-wheeled cars can be used, with subsequent advantages for transversal stability (the center of mass is further to the front) and traction (two driven wheels instead of one). This approach was used by the Messerschmitt KR200 and BMW Isetta. ĭiagram showing an initial velocity vector for three vehicles and the corresponding angular displacement from the initial wheel positions required to change the direction of the initial velocity vector by the same value when turning using various three-wheeled car steering mechanism configurations Two front Ī configuration of two wheels in the front and one wheel at the back presents two advantages: it has improved aerodynamics, and that it readily enables the use of a small lightweight motorcycle powerplant and rear wheel. In 1897, Edward Butler made the Butler Petrol Cycle, another three-wheeled car.Ī Conti 6 hp Tri-car competed in (but did not complete) a 1907 Peking to Paris race sponsored by a French newspaper, Le Matin. In 1896, John Henry Knight showed a tri-car at The Great Exhibition. One of these, the Benz Patent Motorwagen, is regarded as the first purpose-built automobile. Three-wheeler transport vehicles known as auto rickshaws are a common means of public transportation in many countries in the world, and are an essential form of urban transport in many developing countries such as India and the Philippines.Įarly automotive pioneer Karl Benz developed a number of three-wheeled models. Some inexpensive three-wheelers have been designed specifically to improve mobility for disabled people. As a result of their light construction and potential better streamlining, three-wheeled cars are usually less expensive to operate. Three-wheelers, including some cyclecars, bubble cars and microcars, are built for economic and legal reasons: in the UK for tax advantages, or in the US to take advantage of lower safety regulations, being classed as motorcycles. A variant on the 'one at the front' layout was the Scott Sociable, which resembled a four-wheeler with a front wheel missing. Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or "reverse trike" sometimes with front drive but usually with rear drive. Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Other trikes include All-terrain vehicles that are specially constructed for off-road use. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end. ![]() Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. ![]() Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles. Trihawk, a tadpole-type trike manufactured in California, United States during the 1980sĪ three-wheeler is a vehicle with three wheels.
