Default Re: Can I use a power generator engine for a bicycle motor

I know that you didn't hear what you wanted to hear, but you wanted some opinions. Among the issues for me was not the weight of the engine, but it's power. My suggestion would be to do a bunch of research here by reading people's build threads. If friction drive is your interest I'd suggest reading up on cannonball2 and his numerous build threads, several of which are friction drive and economical. A four stroke engine around 3 horsepower would be sweet for a friction drive. Lots of used ones of that size are around from snowblowers and all sorts of things. Watch Craigslist and you'll find your motor for not much money. Maybe sell your generator with motor on Craigslist, too. People here will be very willing to help you answer questions about your project. I hope you do it as it can be a lot of fun and practical transportation, too.
This is the time to do your homework, both in school and out... ha! Good luck.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
