It's probably much better for the urban environment, in terms of people not breathing gasoline exhaust (doubly so for breathing two-stroke gasoline exhaust from a motorcycle, which is more of an alternative than a big car). The lead-acid batteries on some of the cheapest ones are a little iffy, though, and the carbon consumption isn't a huge win.
