superfast (too fast?) electric scooters

Dentists best friends.

JFC these things are free darwin award coupons.
Everything about these makes the stability awful. Tiny wheels, centre of gravity, handlebars and rake angle......
I got thrown off one of these things at 20kmh on the tiniest of bumps. Whats hilarious is that I rode over the same bump with my mountain bike and I could roll over it without even holding the handlebars. The difference in stability is night and day.
Unfortunately the world is full of darwin award candidates, and so the more people do stupid stuff on them, the more government and police attention it's going to bring to everyone else.
Also, I have come off a motorcycle and slid down the road at 80kmh. I had leathers with armor inserts. You wont be dressed like that on one of these scooters, and if you come off you can expect a serious hospital stay with skin grafts.

I don't think two motors gets you too much other than faster acceleration. As long as you have braking on the front and back, which I'm sure all of the high end ones will.
The range is probably harder to find. They seem to top out around ~1500Wh.
This one is only 24kg weight, but looks cheaply made: https://www.voromotors.com/en-ca/products/emove-cruiser?ref=electricscooterinsider

Yes the stability is crap, you 100% have to keep your hands on at all times.
I thought the small wheels were due to a legal requirement but here it is 430mm diameter maximum. Maybe in other countries they specify a smaller diameter?
OP may be better off with an e-bike, if the roads are rough, for sure.

Needs to be a 'Skip-Flyer' to be practical, as in those potholes mentioned...; Partial rolling, towards pothole surface defect, and then, turbine up to speed, it does a 32 foot span 'HOP' barely clearing any ground surfaces.
That's why they call it a 'Skip-Hop' ground effect.

Yeah, and it gets even worse. On motorcycles and bicycles it's advantageous to not hold onto the handlebars too hard. This reduces fatigue, but also reduces the positive feedback loop between your hands/arms and the bars. Ie, when you hit bumps or uneveness, that shock gets sent through your arms and hands to the steering input, which then further upsets the bike.
On the death scooters, I found myself holding on far too hard to ensure bars didn't throw me off again. My hands and wrists got far too fatigued.
