Sorry, stupid question: why doesn't an electric car need to vary its gear ratio?
My experience with electric motors is pretty much limited to capsela cars, and IIRC almost every chapter of the instruction manual contained a note about gear ratios.
Internal combustion engines output more power at a certain band of RPM, so you have gears to stay in that band at various road speeds. Electric engines can produce about the same torque at any RPM, so you don't need gears.
well i'm not sure what's done in electric cars, but in many modern consumer gas cars, part of having an automatic transmission is having a "continuously varying transmission" which is like a cone of gear ratios

Only a few cars have cvts. And to be honest you shouldn't buy one. They are all junk and are extremely expensive the minute they break out of warranty
