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.

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.
