Just use google and type in gas powered bicycle and you will get info..

You're right! I could! Thank you, Ruthie G.

Hope you found some info. Have any links for us? What kind of gas motor do they use? Something small, like from a gas trimmer or blower?

I've heard that the small gas engine might overheat due to the heavy load.. Any opinions/advice? I also have a problem attaching a 60 teeth sprocket to my rear tyre( originally comes with a 6 sprocket cassette).. anyone who has done it b4 pls help!!
