I wonder if he was getting decent MPG on that crazy machine? I've been looking at adding a 49cc engine kit to a bicycle for around town, surface street errand running. Anyone have any experience with this sort of conversion? The price is right if they work decently.

Mileage can vary, with a fast moped like that you can see your mileage drop drastically, down in to the 30's, most mopeds in stock form get 100mpg the two Tomos mopeds I have owned got 80-90mpg for the 1980 Bullet with an after market performance exhaust and my stock 2005 Arrow would get 107mpg or so, bicycle kits tend to get the same kind of mileage, some of them with 4 stroke engines going 20mph get 200mpg if you are light and live in a flat area but the faster you go the more your mileage drops so 100mpg at 30mph is pretty common.

I may try something like that. Here in Missouri no registration is required of it is less than 50cc. As long as I don't have any great expectations it might just work out as a grocery getter. Not much investment required to give it a try.

Re the bicycle conversion you could also look into a plug-in electric setup. I have an engineer friend who rigged up his cannondale to go 50mph+ on an all electric setup using pretty inexpensive components. Its still in the R&D phase though.
