A powertrain system for a commercial electric vehicle includes an electric motor, a multi-speed transmission, and a drive line. A reducer assembly is added prior to connection to the drive line to decease the rotational speed generated by the electric motor prior to being transmitted to the drive line. The reducer assembly can be placed before the multi-speed transmission input, after the multi-speed transmission output, or somewhere in between those two locations. The reducer assembly includes a reducer gearset for decreasing shaft rotational speed. The reducer assembly may include adjacent idler gears to reduce the pressure load on the gear teeth of the reducer assembly.
