I like the $350 HF 142F 4-stroke with 4G transfer case kit from gasbike.net http://www.gasbike.net/bike-motor-ki...-2879-prd1.htm
They typically need a little pedal help to get going so a low geared single speed which is easy by replacing the $2 18T hub sprocket with a 19T or just us a 7-speed bike but once you get them going they run nice and can do ~30MPH.
What really rocks that engine with a SBP shift kit and an internal 3-speed, not need to pedal and they will they 35MPH.
But that is way out of your price range.
