ABSTRACT:
An electric skateboard is capable of detecting a load applied from a rider accurately without influence from various positions of the rider on the board and without influence from various road conditions. The electric skateboard includes a board arranged to receive a load from the rider, a load detection sensor arranged to detect the load received by the board, a front wheel provided on a lower surface of the board, an arm which rotatably supports the front wheel, a first frame connected with the arm, a second frame fixed to the board, and a shaft connecting the first and second frames. The load detection sensor is sandwiched by the first and second frames. A rear wheel is provided on the lower surface of the board and has a construction that is similar to that of the front wheel.
