onewheels suffer from a problem known as nosediving in which the board shuts off when it can't supply enough power to support the rider, as the board is self balancing this is a problem intrinsic to the board's form factor. The board works in a similar fashion to balancing something like an umbrella on your hand, as the rider leans forward it creates an imbalance that requires the board to accelerate in order to keep…

Pushback is extremely unintuitive, it should do pushforward instead.

I don't think that would work, because pitching the board forward would require the wheel to accelerate to keep you upright. Also, what if it needs to warn you while you're actively accelerating (with the board already pitched forward)?

Of course the type of person to ride a scooter on the sidewalk and hit someone will spin it as a lesson to others. It’s too bad you weren’t sued so you could learn to accept so e responsibility.

If anon334455 didn't want to leave a comment, anon334455 didn't have to. What's the point of anon334455 commenting except to warn others to be careful?

Catharsis, ego, etc.

Maybe. But even so, I do think the comment might cause some readers to behave more safely. Someone saying "I did this thing and it had a bad outcome, don't be like me" has more impact that someone saying "Don't do this thing."

And we have still had one of those cyclists (on a traditional road bike) with all of those riding hours, handling skills and instincts, kill an elderly pedestrian on a mixed-use trail around here by maintaining that 20+mph. I'm starting to think e-bikes that go that fast should use traffic lanes intended for cars and motorcycles, not mixed-use trails intended for bicycles and pedestrians.

That's heartbreaking. 20 mph on a mixed-use trail is dangerously reckless, unless you get a long empty stretch out in the countryside. There are always groups of 4+ pedestrians who will suddenly spread out and block both lanes completely, with almost zero warning. If you can't react to that without an accident, you're going way too fast. It would be nice if pedestrians would stay in the correct lane, but it's never g…

According to witnesses in this case, the cyclist called "on your left" (which is the local convention) prior to attempting the pass, and the pedestrian moved left. The descriptions did not sound over-the-top reckless to me.

"Heartbreaking" was really the only word for it.

Isn't the way it keeps the nose up by speeding up though?

No, it uses battery power to self balance once it detects you standing on the board, the nose will stay up at a standstill. This also means if you run out of battery power the nose will just drop on you.

The force to balance though comes from the wheel torque which are from either speeding up or slowing down.
