A transmission system for a vehicle with an electric motor includes a continuously variable transmission having a drive pulley, a driven pulley connected to one wheel of the vehicle, and a belt operatively connected between the drive pulley and the driven pulley such that a pitch radius of the belt in contact with each pulley is variable. The transmission system further includes a planetary gear set having a sun gear connected to the output of the motor, a ring gear connected to the drive pulley, and a planet gear operatively connected between the sun gear and the ring gear. The planet gear is rotatable about a respective planet gear axis which is fixed in position relative to the sun gear axis such that the planetary gear set is arranged to be operable at a fixed gear reduction.
