Well the engine and the bike are real. There is an early bike motor by the name of Steffey. When I say early I mean 1902 to the late teens. this engine is identical to the Steffey, but also were installed on a garden tractor by the name of Sprywheel. Some guys are restoring bikes with these engines and calling them Steffey. So just for fun I put my engine in the frame, which is from about 1890, and other unrestorable pieces like the rusted out tank, etc. The fad these days is to have the original "patina" which in my case is rust. So its half real and half art.
