This looks like it could be a gasBack in the early 70's I had a bike (10 speed) equipped with a "Chicken Power" gas engine that is very similar to this kit I found on EBAY. That thing was a blast to ride and in fact I rode/drove it a few times about 26 miles to the airport where I kept my old Cessna tied down. Anyway this looks like a fun project to sort of re-live my youth! No big loss if it's a POS. I can't remember what brand engine was in the "Chicken Power" kit but I believe it was only a 25cc motor. What do you guys think? http://cgi.ebay.com/50CC-BICYCLE-ENG...d=p3286.c0.m14
