Can I just mention I find it very strange that there are hip techy Silicon Valley startups that invest their time in these scooters, when from a pure engineering perspective these things are doomed to be unsafe. COG is very high above the ground, which makes keeping balance more difficult. Wheels are close to the COG in the horizontal direction, making it easier to fall forward over the steering handle. Wheel radius is small causing the scooter to get stuck behind all pits in the road and stuff like that. I mean sure it’s fun to ride these things but please tell me this is not the Technology Age’s means of transportation. Apart from that I found this article to be quite sensational. I’m missing the cold hard statistics proving these things are actually dangerous, which do not (yet) exist as stated in the article itself.
