You mean continuously variable transmissions? Those could work in an EV I suppose. I don't know much about CVTs but I think the general complaints against them are that they tend to have a narrower highest-to-lowest gear ratio range than a traditional geared transmission, and it's hard to build them to handle large amounts of power.
