Greetings!
I'm sure the Schwinn Super Sport will work just fine. If I remember my Schwinn bicycle models from back then, the Super Sport was a ten-speed "racer" as they called them. I built my motorized bike using a Schwinn "Suburban", which is a 5-speed (no front derailleur shift), but with 27" x 1.25" road bike tires, and a more upright, "cruiser" style seating. It works just fine! The engine (low priced two-stroke kit) fit nicely into the frame, and with the bulletproof Chicago Schwinn construction, nothing has broken yet. (I had to upgrade the rear tire and tube, though. Frequent flats due to the stressful life the engine subjects the tire to.)
Good luck!
