I love it, but I also build extremely powerful electric bikes (one that goes 85km/h), so I'd take the frame etc and put decent power in it with a legal switch hidden somewhere. That way I could keep up with traffic if needs be, something I feel keeps me safer at times on my commute.
To be honest though, I don't really see a need for it in a warm country, and this not having a second seat wouldn't be able to replace my car for hauling the kid.
