1. An installation method comprising:

  • providing an electrical vehicle including a frame, an axle fixed to the frame in a non-movable manner relative to the frame, a hub rotatable on the axle, a pedal rotatably mounted to the frame, and a driving chain extending between the pedal and the hub; and

    installing a strain gauge sensor at an installation location on the frame spaced from the axle and the pedal, with the strain gauge sensor generating a deformation signal measuring a pushing/pulling force applied by the driving chain, with the installation location of the strain gauge sensor satisfying the following methods;

    Method 1;

    when the pushing/pulling force is applied by the pedal to the installation location of an electrical vehicle, the installation location is deformable and a deforming action force is directly proportional to the pushing/pulling force;

    Method 2;

    when the pushing/pulling force is applied, the vehicle deforming direction at the installation location is independent to a pushing/pulling force moving direction; and

    Method 3;

    a strain detecting direction of the strain gauge sensor is in a same direction as a vehicle deforming direction at the installation location.
