My Son works for a bicycle mfg and recently he obtained a carbon fiber frame from work and custom made a bike with a little 1 cylinder motor on it and started riding it to work. About 4 miles 1 way. It took him a month to use a gallon of gas. I rode it and it is fun. It will go 30-35 top end but it cruises nice at around 20mph or so. We clocked the speed of it with a car. Now everybody in the shop wants one.
Lots of makes and models. I'm wanting to get a 2-stoke in frame engine and do the bicycle up MX style.
Thanks for that info. I checked it out and there are a lot of people on there. I gave it to my Son. He had no idea (nor did I) there was a website for motored bikes.
