Why does combustion engines need multigeared transmission while electrical engines can make due with a single gear?

Question

So trying to figure out why electrical engine only needs a single gear while a combustion engines needs multiple gears. Cant wrap my head around it for some reason

EDIT: Thanks for all the explanation, but now another question popped up in my head. Would there ever be a point of having a manual electric car? I’ve heard rumors of Toyota registering a patent for a system which would mimic a manual transmission, but through all this conversation I assume there’s really no point?

Answer 1

Variable frequency drives.

You can get a multitude of speed control by handling the Hz and voltage to a motor, a VFD is essentially a transmission for a motor. Without one it will spin at a set speed based of the wiring of the poles and the voltage. A VFD and specialized motor will give you a multitude of speed control / torque

Engines have transmissions that do this.
