Inventive embodiments are directed to components, subassemblies, systems, and/or methods for electric traction drives employing a continuously variable transmission (CVT) having a variator provided with a plurality of tilting traction planets and opposing traction rings. In one embodiment, an electric traction drive is provided with an electromotive device configured to transfer power to or from a traction sun of a CVT, In other embodiments, an electric traction drive is provided with an electromotive device that couples to certain components of a CVT such as a traction ring, a carrier assembly, and a main axle. Various inventive shifting assemblies having shift cams and shift cam cages can be used to facilitate adjusting the transmission speed ratio of a CVT. Various related devices include embodiments of, for example, a power input apparatus, a speed ratio shifter, a shift cam actuator, a shift nut, and a carrier assembly configured to support the tilting traction planets.
