1. A method for absorbing shocks encountered by a self-balancing electric vehicle, the method comprising:

  • rotating a wheel of a one-wheeled vehicle around an axle using a motor assembly, the vehicle including a board tiltable about a tilt axis oriented perpendicular to a direction of travel, wherein the vehicle is configured to receive left and right feet of a rider oriented generally parallel to the tilt axis;

    measuring tilt orientation information of the board using at least one sensor;

    based on the tilt orientation information, using a motor controller to cause the motor assembly to propel the vehicle; and

    compressing and expanding a shock absorber in response to the board moving relative to the axle as a result of wheel movement during operation;

    wherein the shock absorber comprises a first linkage assembly connecting a first end of the shock absorber to the board, and a second linkage assembly connecting a second end of the shock absorber to the wheel; and

    wherein at least one member of one of the linkage assemblies is rotatable on an axis extending perpendicular to the direction of travel of the board.
