They don’t need them.

Transmissions are needed for internal combustion engine cars because ICE motors need to maintain certain RPMs to produce useful power. This is often a range of about 1000 to 7000 RPM… and worse yet the best power and best efficiency are at even smaller ranges (and those aren’t the *same* ranges).

The solution to this is to have multiple ratios of engine to wheel speed; 1st gets you moving from a dead stop and the top gear is for cruising at ~2000 RPM at highway speeds.

Electric motors don’t need this because they have a (nearly) ‘flat’ power curve; you can start from a dead stop, accelerate, and cruise at highways speeds all with the same gear ratio.
