Well, no more: Industrial designer Adrian Van Anz has created a stylish, retro moto-bike that looks like a cross between a Ducati and a Schwinn. Behold, the Derringer Cycles:
Derringers can be pedaled as a traditional bicycle, propelled via engine power, or pedaled with the assistance of engine power. While under power, the pedals can also remain stationary, allowing you to operate in the style of a traditional motorcycle. Capable of fuel economy ratings that can exceed 150 mpg, Derringers are the first product to take the compromise out of environmentalism ...

Admittedly very much cooler than the ones that were on the market 30 years ago. The uncoolness of mopeds is what killed them, imo- these guys have taken a good approach (especially in appealling to the "green" fad).
It is nice to see this particular concept of cheap, efficient transportation is regaining popularity.
Incidentally, while I would hop on one of these in a heartbeat, I wouldn't be able to keep it as my primary form of transportation. Where I live, it just isn't practical -- we have these things called "winter" and "thunderstorms." I don't care how green it is, I'm not riding an open vehicle in that kind of weather. It's just not pleasant (or safe!).

look too nobby.
I found spookytooth a while back when looking into adding an electric motor to my bike for summer commuting. The electric is a nice option, but limits your range a bit.
