I was born in Pontiac, MI. The Whizzer Factory was on my paper rte. A neighbor of mine was lucky
enough to have a dad that put a used Whizzer engine on a very old motorcycle frame. Quite often, he would let me ride it. The frame was complete with crash bars and foot pads. There was no way to start it...except pushing. The centrifugal clutch kicked-in and we jumped on hopefully without tripping over the crash bar-foot pad combo. Then once we got going...did I mention there wasn't any compression release lever? We just had to slow it down enough to let the centrifugal clutch kick-out. It was the worst thing on two wheels, but we loved every minute. Unless it quit at the bottom of a hill that was uphill in both directions. that meant we had to push it uphill so we could run it back downhill and hope it started before we hit the bottom again.
Anyway here's a little trivia that very few people know--the Whizzer Factory was located at the corner of S. Sanford and Osmun St.
I just found out about 2 months ago that Whiizzers were back. I was planning on getting one just about 3 days before our air conditioner quit.
