It is getting too hot. I really enjoy my Happytime. I would like something that does not buzzz so much. I found goped nation Ehhhh!!! I also found an $42.00 plus 15.00 shipping total cost mod that attaches a continuously variable transmission. to a small engine. I am planning on building a rack mounted friction drive or a chain drive version with a 62 tooth rear sprocket. The friction drive version would be a complete backend off a go ped with the cvt mod , using a solid rubber convex drive wheel. Quite possibly NO slippage with an automatic transmission. The chain drive version is a 10 tooth output gear with some BMX chain and a 62 tooth rag mounted rear sprocket from andyinchville's sprocket sales.

I have had people get mad at me when I tell them how much I spend on gas per month. Wait till my average gas price goes to $2.00 per month. My happy time cost four fill-up's. About a months worth of gasoline for an average car. LOL! Add another Rackee to the tally.
