I also ride EUC's. They are even more fun than e-bikes IMHO! But they're more expensive and certainly more dangerous and come with more bodily risk.
I have a gotway begode EX.n and a king song 16s. I am currently waiting on a king song s20 to ship AND hope to buy an inmotion v12 soon.
I haven't tried one, but I'd like to. On group rides in Detroit, we usually have about 5 EUC's, 20 OneWheel's, 10 e-bikes, and the rest e-boards and scooters.
