Not certain of the manufacture of this bike. Bike was made in the USA during WWII probably by an Ohio based bike company. Bike may have been an exercise in attempt to make a bike with less materials for defense plant workers. Front and rear utilize mono leg design. Front and rear New Departure hubs are built specifically for single side attachment, the rear coaster brake has no external coaster brake arm, the job of the coaster brake arm is dealt with a oversized axle. Both hubs have the original black satin finish that was typically used during WWII as a substitute for chrome plating. The S shape frame supplies a great deal of compliance and affords comfort bike style suspension although the bike is all original the original finish had been repainted with primer before I acquired it.
