Two days ago, I stopped at the grocery store on the way home to pick up a few things, and parked in front was a cheap mountain bike with one of those little two-stroke motors on it! As I stood there looking the thing over, the owner came out and we started talking.
To make a long story short... he's an engineer-type nerd like me... and he made some changes and tweaks to the system. He has this thing going at a top speed of about 45MPH (he mounted a disc brake suspension fork for safety) and it's getting almost 280 MPG!!
I know the emissions of the two-stroke are worse than its 4-stroke bretheren, but hell's bells... how bad could the emissions be for a vehicle that's getting 280 miles on a single gallon? I'd venture to say that it puts out waaaay less than ANY conventional auotmobile on the road.
TC-W3 2 cycle engine oil is designed to be environmentally friendly when used in a properly designed 2 cycle engine. Combustion is near 100% so pollutants emitted are very low. So low in fact the EPA has granted import certification for those little Chinese bicycle engines. They had been banned from importation for 2006 and 2007 but with a new tuned exhaust system and the use of TC-W3 oil those little engines passed strict EPA requirements. I purchased a Chinese bicycle engine in 2005 and wore out the first bicycle I installed it on. I built another bicycle just for that engine. I'm very happy with it. It does not smoke or smell and the stock exhaust is very quiet. Here is a picture of my motorbike.
