Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles, heelies, or an office chair: 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.

I mean, yes, all that's true, but they were also doomed from the get-go just because the huge bearing creates so much more unnecessary friction. Did you see how poorly it coasted? That negates one of the biggest advantages of cycling over walking all by itself!
Engineering-wise, large diameter bearings with low friction are entirely possible. This just happens to be one of the worst implementations of a large bearing, in an application where it really, really matters to be low resistance.
My point is that low-friction bearings still wouldn't have saved this design from impracticality, so focusing on just the bearing issue would be giving a free-pass to the rest of the design pitfalls of this monstrosity.
