In 1913, Hugo H. Young and Carl F. Dudte founded the Flexible Sidecar Co. in Loudonville, Ohio, to manufacture motorcycle sidecars with a flexible mounting to the motorcycle. The flexible mounting allowed the sidecar to lean on corners along with the motorcycle, and was based on a design patented by Young.
In 1919, the company's name was changed to The Flxible Co. (still pronounced "flexible") so that the name could be registered as a trademark.
After low-priced automobiles became available in the 1920s, the motorcycle sidecar demand dropped and in 1924, Flxible turned to production of funeral cars (hearses), and ambulances, which were primarily manufactured on Buick chassis, but also occasionally on Studebaker, Cadillac and REO chassis, and intercity buses, initially (1930's and early 40's) built on GMC truck chassis, and powered with Buick Straight 8 engines.
