I saw there was a big push for 2 wheelers with good sucess. I hoped to see one of the most basic vehicles out there, a Bicycle and a bicicle with a small 2 or 4 stroke motor attachment. There are many brands of 2 stroke engines and 4 stroke engines. There are also many types of bycicles. Raceing type engines will make the bicycle move fast, average standard engines will help the bike glide along. If we have more luck with the 2 wheelers this is a must in my opinion.
