Uh, those motors on those things are dumb ideas.Someone should have thought of them. Joggers, but no bikers? What's that all about?

Was talking survival with some survivalist friends and we agreed a small 4 stroke friction drive on a good mountain bike that would run on home made corn squeezin's would be ideal !If it don't burn gasoline...it ain't no motorbike.
Technically we should call them engine bikes. Then there would be no confusion about what's in the fuel tank; fossil fuels or volts.
