The present invention relates to a two-speed transmission for an electric vehicle, which comprises: an input unit providing power; first and second transmission delivery units individually engaged with both sides of the input unit; first and second transmission gear units individually connected to the first and second transmission delivery units, and transmitting power through combination of gears with axes crossing each other; first and second braking units individually connected to the first and second transmission gear units to provide a braking force; and an output unit connected to the first and second transmission gear units to discharge power. Therefore, manufacturing costs are reduced, and a transmission ratio can be freely designed.
