Abstract: Disclosed is an electric surfboard that can determine whether or not a user is on board while the surfboard is working, and if not, can stop operation of the surfboard, and that can naturally cool heat generated from a control unit and a motor unit. The electric surfboard includes a surfboard housing, foot bindings which are put on a user, a step-out detecting unit for creating a magnetic field and attracted to the housing by a magnetic force, as well as being physically coupled to an ankle strap, in which if the user steps out of the surfboard, the step-out detecting unit being detached from the housing, thereby detecting step-out of the user, and a control unit receiving a step-out detecting signal outputted from the step-out detecting unit to send a signal for stopping operation of the surfboard.
