micromobility - Ebikes, scooters, longboards: Whatever floats your goat, this is micromobility
Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

Couldn't they just put like a small wheel on the front that only got used if they dip too far that way it's not a slingshot. Like it's still "one" wheel when it's used normally.
That still leaves the problem that when it hits top speed, the user is leaning forwards.
When the acceleration stops, the physical effect is the same as when you are leaning at that same angle, but standing still. That the board would be able to continue rolling at that same speed, doesn't solve the fact that to get under a leaning rider and to keep them fom hitting the pavement, it needs to accelerate, not just maintain speed.
Going from top acceleration, to no acceleration, is the same as going from no acceleration, to full braking, front wheel or not.
Thanks for this detailed explanation.
These are everywhere in NYC. Last year, a guy who passed me in the bike lane on one of these ate shit for what seemed like no reason a block and a half after he flew by me. I stayed with him until the ambulance arrived and never saw him again, but I always wondered what caused his fall. Now I know.
It's unfortunate. I met a guy who gushed about how amazing his high-performance EUC was. How it cannot fall over because it's gyroscopically stabilized and I had to sit him down for a long talk to explain to him all the limitations of these things. He was under the impression that it had some kind of ABS braking, too, which supposedly made it safe to ride on ice.
They are often advertised to have E-ABS, which is just a marketing term for regenerative braking. It doesn't actually provide the benefits of ABS on motorcycles and cars, which are smart braking systems which rely on traction-sensors from more than one wheel. Real ABS is not possible with just one wheel. And active balancers need 100% traction 100% of the time. They need torque to self-right, and without traction, there is no torque.
Yes, they are amazing, but they aren't nearly magical enough to be stupid-proof. You need to know how they work to really ride them safely.
ABS only needs to sense when the wheel locks up, or stops spinning. You only need one when for that. Traction control usually uses multiple sensors, maybe you're thinking of that?
Except a wheel doesn't need to actually lock up for braking to cause loss of traction. Modern ABS systems don't just pulse the brakes when the wheel stops spinning, it does so upon loss of traction. To determine whether traction has been lost, one wheel isn't enough of a sample size. The ABS works in tandem with traction control.
Regenerative braking cannot lock up, which is where the whole idea of calling it E-ABS got started, but it absolutely can still brake hard enough to cause loss of traction. I experience it all the time when slowing down on gravel with my electric skateboards, for example. It simply doesn't, and cannot, work the way ABS does on a mechanical braking systems, where braking is pulsed to regain traction the instant it is lost.
Yes, all ABS really means is anti-lock braking system, but what most people expect it to DO is to guarantee that traction is maintained while braking. (Even though that isn't technically correct, either)
