The Kelsey automobile brand, produced in the United States from 1899 to 1919, was an early American motorcar manufacturer noted for engineering innovation and quality craftsmanship. Founded by Edward C. Kelsey with offices in Flint, Michigan and later Detroit, Kelsey built a range of vehicles including runabouts, touring cars, and roadsters powered by single and four-cylinder engines. The marque was particularly known for pioneering early safety and comfort features, such as the Kelsey Motorette, one of the first affordable cyclecars, and for its durable, lightweight designs. Production ended in 1924, and Kelsey is remembered for its contributions to the formative years of the U.S. automobile industry.
