I have been lurking in these forums for awhile and debating whether I should by an engine kit. A few days ago I finally decided to buy myself a bike kit and I went with a 80cc Chinese kit off of ebay for around $145 with shipping from Zippybike. I have wanted one ever since I was a kid. I used to see the kits in the back of Boy's Life magazine and would dream of building one. I'm excited for the project. I will be attempting the install on a early 90's GT mountain bike that has sat in my shed for the past 10 years. I was originally going to put the motor on my Electra Revil cruiser but I'm certain I will have clearance issues on the frame and on the fat rear tire. I most likely wont have time to start the project until November as my band will be on the road but I will post pictures and let you guys know my experiences!
