Are there advantages to sticking with such small wheels on a powered board like this? I'd think that something like this [1] but with a motor would be way more usable on real-world streets. In general though, I really do think that these kinds of "personal transportation" devices are the way of the future. I ride my self-balancing electric unicycle [2] from the light-rail to the office any time it's nice out and I'm not hauling anything in. It's the best way to get around in the city as far as I'm concerned. I feel like it's a better solution because of the big, pneumatic tire. I can ride it up a bump of about an inch without even thinking. I feel like it'd be quite a challenge to ride something with wheels that small on the roads/sidewalks/trails around here (Minnesota).

Carrying this thing around for extended periods of time can get tiring.
