Actually- aren't the laws just a bit antiquated? Because all the time there's new and different products. Here's an ad for a 50 cc scooter- a really good one and good buy I think.
It conveniently doesn't describe the tranny- I even queried them and got no answer- I was just interested, so I'm not gonna call them. I'll bet it's a 4 speed "semi-automatic" with a centrifical clutch- meaning you shift it with a foot lever, but it can slow down in gear otherwise-
but really NOT much different from a "moped" like this one on another site:
that sells for hundreds more- just because of the ad. And probably priced higher because of the laws- put in place largely to sell more gasoline and discourage such transport.
