Very cool.

I'm curious how much power it would be able to put out for a bike.

A little small, but you would definitely need wide cranks.

Creative Engineering should take a whack at this...maybe even modify it to be 49cc :) He's probably one of the few of us that would have the proper tools and knowledge to make one of these.

He says it's all from round stock I don't see anything from the picture I can't make on a mill & lathe. It's the time it takes!

Yes, I do hope Creative Engineering would see this thread. He has all the tools and knowledge to build one of these babies, not to mention the expertise too. But I don't think he has the time to build one... :-(
