Ebikes, scooters, longboards: 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.

Bike gears are just not meant for this kind of torque. Cassettes get worn way faster at 750W + rider output. The derailleur transmission is lightweight and cheap, but it has limits and needs to be abandoned if you go much higher.
Who was talking about using bike gears? But also, you should abandon derailleurs at any speed unless you're racing the tour de france. The only advantage they have over internal hub gears is weight. And hub gears can be easily made strong enough to handle that sort of torque.
But you wouldn't necessarily need gears At All for something throttle driven. Electric motors have more than enough range of RPM on a single speed gearing system to get to 45mph. E-bikes only have gears for the human component, not the motor.
