"lightweight, short-distance personal transportation is something we’re interested in" I think that's called the bicycle. (Of course there are plenty of barriers to people actually using the things, especially in the US, but those have little to do with the machine itself and everything to do with the social context in which it's used. If a startup can manage to solve those problems then more power to them. Start by talking to the Dutch perhaps.)
