I changed my build off bike to this build. It will be built to honor the Special 8, a straight eight motor made by Pontiac way back when. I thought only Buick and Oldsmobile made that motor, but Pontiac did too, and a special version was made for the Pontiac Bonneville Special sportscar. Only 2 were made. It was a two seater so my tandem frame, a 1963 Schwinn Bicycle Built for Two frame will work just fine. A little background: from wiki: "At the General Motors Motorama for 1954, Pontiac debuted its all new Bonneville Special, a concept car envisioned by head designer Harley J. Earl. The concept was equipped with the "Special"-8, a high output 268-cubic-inch (4.39 L) engine that was painted bright red and detailed in chrome. This was a unique configuration for the "eight", installed in the only two Specials ever made."
