At the age of 14 Andrew Riker built an electric motor in his parent's basement in New York City. Riker later built the first electric vehicle in the United States, in the form of a battery powered tricycle. It was called the Riker Electric. A Riker electric tricycle beat a gasoline automobile built by Duryea in a race in 1896. the Riker electric was built until 1900, when Riker switched to building gasoline powered automobiles.
Riker made electric trucks, and built a two person racer which set the world land speed record in 1901 at 57.1 mph. One of his vehicles set a speed record that endured for 10 years. Riker was hired by the Locomobile company to design a gasoline powered car for them, and switched his interest to gasoline engine automobiles.
