I bought a motorized bicycle engine kit off CL a couple years ago for $125. Put it on a fixie/single speed type Walmart special I got for free. Found out it needs a coil, haven't got around to ordering one, only $10. I like riding my bicycle(non motorized) up and down the alleys in my town looking for scrap. One time I found a drop ceiling type four tube 4' fluro fixture. Carried it in one hand and the other hand on my handlebars and got it home. If I find something bulky I'll run home and get one of my vehicles. I perfer not to do any scouting in my vehicles because I don't need to be wasting gas, plus the exersize is good for my knee.
