ABSTRACT:
A remote controlled electric skate-board has a motor to drive two sets of sun and planet gear units connected with a pair of rollers rotated to move the skate-board by a remote controller transmitting a signal to an electronic circuit carried on the board to start or to stop the motor so that the skate-board may be moved or stopped by electric power in addition to human force.
