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.

More torque sounds great, but I imagine current ebike components are designed for the amount of torque they are expected to be under now.
For this to work well, all the bits on the receiving end of the extra torque need to be prepared for it.
I have a e-bike kit with a chain that skips under the torque of electric motor but not normal pedaling. It’s proven difficult for local bike shops and myself to diagnose as it can’t be reproduced on a bike stand where the wheel spins without resistance. Something about high torque is the trigger.
Shimano LINKGLIDE cassette and chain should be able to handle that much torque and more. It's got more metal where needed and is a bit heavier as a result. You should try it.
New Shimano XT can take 200Nm for a bit but it gets eaten relatively quickly if you keep running that much torque through it.
Importantly, most drivetrains have to be able to handle 200-ish Nm of torque because that's what gets applied when you ride standing up. However the ones intended for human use don't handle that torque continuously. Every time you run that much torque through it, the metal surfaces wear out significantly more so after some wear, you get abnormal behavior.
