  1. The main safety concern though is not the riders who indeed should know their risk, but everybody else who may not know the risk and should not need to care. Protecting our fellow citizens should be our main safety concern, always, not protecting ourselves. Of course, if you only meet one of them twice a day, this concern doesn't need to be that big.
  2. On a decent wheel like the InMotion I would be pretty confident that a cut out only happens when one exceeds the maximal speed (which should be beyond 30km/h for the V5F). Before that, the wheel might still not be able to deliver enough power to keep the pedals horizontal. Fortunately, this is quite different and a situation from which I have recovered in the past without going down. Tiltback advances the wheel in front of the rider and makes it very difficult to accelerate further. That's what it is for. I have the same impression as you though: hard braking seems to become more difficult under tiltback and one may well have the fear to slide down the pedals. I think, as usual, bent, soft knees help to mitigate the problem even though they make the foot positioning even more awkward in this case. I also agree that tilt forward can be a perfectly feasible way to notify the rider to slow down and it has happened to me once or twice on different wheels when I apparently reached the power limits of the motor. A wheel that gets suddenly soft and mushy gives a great incentive to slow down. I don't think though that it would have the advantage to make braking easier. In particular to initiate braking becomes rather more difficult.
  3. I think to set the tilt back speed to a lower than the maximal value is a good idea and the best you can do. I am doing the same on my V8. This has two beneficial effects. The wheel is always further away from its power limits and from its cutout speed, and when a crash happens, it happens at a lower speed. I do not expect the wheel to ever cut off due to running into the tilt back speed but only due to running into/over the cutout speed.
  4. Yes, it's perfectly OK. The only downside: due to the weird and changing foot positioning, the wheel may be more difficult to control.
  5. I was just citing what you said: Aaaaand of course, with higher voltage comes higher power motors... If you define an increase of 25% to be going through the roof, right Just for a rough reference: EUC: 1kW at 60V -> ~17A Tesla: 2x200kW at 400V -> ~2x5000A
  6. It took much longer for me. Less than an hour but certainly way more than 10 minutes. I would calculate 20-25min for changing the battery. That is the reason why I abandoned the idea to carry a second battery for increasing the range.
  7. I have never heard of a firmware update for InNotion wheels.
  8. All true (well, almost, higher voltage does of course not always come with higher motor power. Voltage and power are independent specifications. We can well have a 50V 1000W motor and a 100V 400W motor). Nobody in the right mind would deny that there is a difference between 67V and 84V. Yet, this seems neither to explain why this 25% difference may be decisive, nor that any of these consequences cannot be achieved through other means, e.g. 25% thicker wires or...
  9. Depends on which market one wants to take over

  12. Analysing the data, I found a negative correlation between tilt back angle and current in the above graphs. It remains negative when taken from second 31 or when removing acceleration in a multivariate linear regression. AFAICS it's not likely a direct causal link, as I still have no reasons to believe that tilt angle effects energy demand.
  13. That's right, the current is not limited in a controlled way. Then the weakest element in the chain is likely the battery with the smaller voltage experiencing an overvoltage and overcurrent under charging.
  14. Is it multifunctional in that the wheel can rest on it staying upright? Should be doable.
  15. I have been letting ride quite a few strangers, mostly kids, but not only. I can't even remember a single case of someone who was brave enough to get on and obviously put off afterwards. There was one girl who I didn't even manage to get standing on the wheel (my fault, I guess, I have a steep and slow learning curve as an advisor), who I assume wouldn't consider to pursue even if she had considered before. It helps though that the "brave" are usually above average in climbing the initial learning curve.
