In 1896 Henry Ford named his first vehicle design the "Quadricycle". it ran on four bicycle wheels, with an engine driving the back wheels.[1]
In 21st century France, a quadricycle is a 4-wheel car that cannot go faster than 45 km/h (28 mph), weighs less than 425 kg (937 lb), and has a maximum power of 4 kW (5.4 hp).[2][3] In the United States, a similar classification is the low-speed vehicle class.
