The motors don’t but the drivetrains often do. Not for multiple gear ratios usually but to get a good ratio for it particular motor in the car. But IIRC some EVs do have two speed transmissions because high RPMs might not necessarily be the most efficient for an electric motor even if they can be reached.

Electric motors don’t use gears… we have gears to grind because the oil companies have made a lot of people think they’re necessary.

Are you selling me something?
Or are you trying to insinuate I’m gay?
Either way, I’m not converting to Islam
