I was letting my mind wander when suddenly the notion hit me that it would be really cool to have an electric scooter that could be carried in a backpack. You could ride it on suitable surfaces, carry it over rough ones, go pretty much anywhere. This seems like such a good idea that I did a quick search to see if anyone had actually done it and came up with this. I don't know if it is any good or not but I really like the idea. What do others think of this?
