Electric motors have a wider rpm operating range than gas, but they still get limited at lower speeds so gears are often needed. Of course there are several different ways to wind a motor with different trade offs, but in general you want a few gears.
You’re not gaining a lot for the increased weight and added complexity and decreased reliability for having a gearbox, you’ll just end up with two gears and still no ability to manually shift.
There is next to zero need for more than a single speed unless top-end speed is required. That is why not a single EV motorcycle that I know of has more than one gear, and almost no EV cars (except for the Porsche Taycan and I think one of the Lucid models) has multiple gears either. Everything else is fine with a single speed, but they tend to quickly lose power above 100 MPH or so (which I think most people think is perfectly fine).
