  1. It's interesting to see the history of "Electric single motor wheel for pedestrian" . I thought Inventist "invented" the solo wheel. I was wrong. Stunningly similar wheels were issued patents as back as 1977! See the links below. My question was, how did they manage "self balancing" back then? That technology was introduced by Segway...like in 2000 (AFAIK). https://www.google.com/patents/US4109741 https://www.google.com/patents/US20090266629 This last one is of course by Inventist. http://www.google.com/patents/US8807250 Your thoughts?
