What is a nosedive in this context?
> Once the device senses that it is getting dangerously close to these limits, it shuts off. This wouldn’t be a big problem on a regular motorized scooter, moped, or other comparable device, but the Onewheel has self-balancing technology that requires power. Instead of simply cutting off additional forward momentum and letting the user coast to a stop, the board lurches violently forward into the ground as soon as the motor stops, according to the reports of injured users.
What do you think should happen at that edge case? Preferably in a way that adheres to physics…
Why this feature wasn't implemented after the first prototype ever made is completely beyond me. Seems like a literal no brainer. The "bump" feedback can easily be mistaken for an uneven road surface (ask me and my broken ass wrist how I know) but a board buzzing and audibly yelling at you is hard to mistake.
The nose starts lifting and it’s quite obvious. I’ve heard the term “Captain Morganing” in multiple groups of riders, because that’s how it feels if you’re not aggressively leaning into it to go faster.
The GT already has an audible alert, it’s less obvious than pushback.
Amazing, would love to hear how this works!
It seemed like vernon99 was talking about nosediving from a complete stop(trying to go from motor off -> motor engaged but the motor doesn’t engage), whereas in the post you linked to, I was talking about starting from having the motor engaged already at a low speed (ie <5mph slowly moving back and forth waiting for a light) and then the power would just drop out.
Same result, but likely different causes.
If I had to guess, it sounds like the motor hits some thermal limit and cuts out. Which would explain why it happens at red lights often, lots of high torque motor excursion performing small moves to maintain balance, but little to no airflow because the motor isn’t moving fast enough to pump air through itself.
