The Schwinn Stingray has gone through a lot of evolution, from its beginnings in the 1960s to its more recent chopper style versions. I guess the chopper styling motivated some owners to take the next step and put an engine into the bike and create an actual motorcycle. Putting engines on bikes is certainly nothing new, it’s been done for a century or more but I hadn’t noticed much activity recently until I saw this one for sale. Interesting.
