I'd be in if they make a kick scooter, I wouldn't be comfortable at that speed on a one-wheel. Is this meant to ride in the street?
I love that they support right to repair. That's my big concern with my ninebot, if something goes wrong it seems to be really hard to get parts. I can't even find the 5A DC charger in stock.
If I need to replace a tire I feel like I'm going to have to ship the whole thing somewhere.
My question stands I suppose - is this meant for the street? I usually see these on sidewalks zipping through crowds, so I'm just imagining that if you gave someone one that could do 22, they'd be doing that instead of the 10 or whatever most do.
Side note, is there a practical limit on acceleration given how fast you can change the position of your body? The ground speed is just a product of trying to keep the center of mass above the center of the tire's contact patch, right? If you just lean forward and push it to go faster until it hits it's limit, wouldn't you go over from the Δa?
About acceleration: you're 100% right. I can easily overpower my current wheel by overleaning it. But the more power a wheel has, the harder it is to overpower it and fall forwards.
Wheels don't actually have a "top speed" (technically they do but it's impossible to hit), they just have different power. The more power, the safer they are and the faster they can accelerate and the better they can balance. A heavy rider may cut out at 22mph, but a 100lb rider might cut out at 30+.
A heavy rider may faceplant when simply accelerating slightly too fast up a hill too, even at 5mph.
Also, onewheel GTs can easily hit 22 today, and even faster for light riders. People just don't like to ride that fast usually.
