@gadgetrider I totally agree, you won't get pushback from me (I am not sure if the pun was intended :-). I commute to work on my board as well as go on small (what fits in my backpack) shopping trips. Riding with knees bent is essential as I often hit some really bad road conditions (uneven pavement, pinecones, rocks, holes), most of which I steer around but not always; the board handles it much better than I expect. I thought pine cones would feel worse than they do.
In addition to your motor torque comments, the acceleration of the board is not fast and that is where I think many people go wrong. If your stance is not "correct" then you may not realize how much torque you are asking of the motor. My nosedive happened because of this, as I had more than 50% battery (with balanced cells), smooth rode, not moving very fast, and no obstacles. Since I changed my stance (as described by both of us and the wiki), I have scraped the nose (my fault) without any incident. It would have been a nosedive had I did the "full body lean" even at less the 10 mph. Again, I completely agree with your comments.
