In this way the wheel parameters would be complemented with the information about forces acting on the rider. Of course, a phone is not usually rigidly attached to the rider, but it could still be very valuable information in the analysis of such events. This would have been greatly entertaining in the aftermath of my skid out on Saturday, when I could then measure just how hard I thumped into the ground 1 1 Quote Link to comment Share on other sites More sharing options...

You must have been reading other peoples post where they say it can't happen. you know, the flat earth society, armchair expert crowd. How hard did you flap your arms? Try it again at 35kph, and report back. Edited May 29, 2019 by Smoother 1 Quote Link to comment Share on other sites More sharing options...

Whats my speed? How fast am I accelerating? What battery level am I at? What's the slope of this hill? How hot is the weather? How old is my wheel/battery pack? Whats my PSI? What temperature is my mainboard and motor wires? What firmware am I running? How windy is it? Is it raining? Am I restricted from riding here.. This is a good description, imho, of what should be known to a rider while riding. I say" known" rather than "constantly thinking about" because some things, like battery % don't change that quickly, so, for example, If I have only been riding a few minutes and my wheel started at 90% charge, I don't have to think about the battery for now. After riding for half an hour though, it needs to be considered, even if to be disregarded again for a while. I think at some point in our riding life, ALL these considerations are automatically assimilated into ones riding behavior and it just isn't the mental work out it appears to be when written out long hand. But it is an excellent description of what one should be considering while riding, plus all the other stuff about obstacles, traffic, pedestrians, dogs, children, the police if applicable) etc, etc, etc. Wow! it sounds mentally exhausting. Thank God We know it isn't. Quote Link to comment Share on other sites More sharing options...

I shouldn't be laughing but you sound like you're ok. How hard one "Thumps" into the ground, now that WOULD be interesting.

If one would have the exact data with a good timely resolution the points in a diagram would look like a "cloud" - by the self balancing the wheel is always in some "torque range" and "speed range" changing a couple of 100 times per second. So if one nears the limit, this "cloud" starts to touch the limit with some of its periphery. At this "outliers" the motor cannot deliver the full torque, but as these are just some "seldom" points and the majority of points in the cloud are well within the limit where enough torque is available, everything is still "ok" but not as perfect selfbalancing as if the whole cloud would be within the limit. This is imo felt as the "pedals getting weaker" - or one gets a bit a bad gut feeling of "missing support". The nearer one comes with the "center of the cloud" to the limit, the worse the self balancing of the wheel gets. Delighted to receive such a constructive criticism and in depth analysis of general overleans and log analysis. Thank you very much, was very educational and eyeopening, always willing to learn. 3 Quote Link to comment Share on other sites More sharing options...

I'm absolutely fine the right knee that went down was completely uninjured thanks to d3o knee guard inserts in my riding jeans - a couple of scrapes on my left palm which wouldn't have happened if I hadn't left my riding gloves airing and forgot them 1 Quote Link to comment Share on other sites More sharing options...

What is amazing is that it monitors the tilt position and adjusts the speed of the wheel several hundred times every second. That makes the pedals feel like a stable platform. But they are not any more solid than when the wheel is powered off. All the stability comes only from accelerating the wheel with incredible precision. Nothing more. Exactly! Well said! All the magic is in the automation, but the magic "wears off" when you hit the physical limits. That's what trips people up. (My wife overloads the washing machine all the time. Maybe if it caused a face-plant, she'd stop doing it.) 7 Quote Link to comment Share on other sites More sharing options...
