The Flxible Company, not unlike many other companies, had a modest, but unique beginning. In 1912, Hugo H. Young had an idea for a new type of motorcycle sidecar.  In 1936, it was decided that Flxible would concentrate on inter city coaches, and all its resources were devoted to developing a coach that would be outstanding in this field. In 1939, Flxible introduced its famous 29 passenger Clipper powered by a modified straight-eight Buick engine. Flxible produced a variety of models of one and two level inter city passenger buses through the 1950’s and 1960’s that have since been converted to motor homes.
