An electrically driven brake controlled skateboard employing an electric motor and associated battery mounted on the bottom of its foot supporting board employs a pulley arrangement whereby the initial slipping of its belt acts as a clutch for transferring rotational power from the motor to a U-grooved drive wheel of the skateboard. The U-groove is low cut so that the drive belt is partially exposed to the road surface. A dual purpose tether mounted brake control and on/off switch is used to control the braking of the skateboard and the energization of the drive motor.
