1. A method of setting a current-limiting value by adjusting parameters of control circuit of an electric vehicle motor, to set a predetermined upper current corresponding to a rated current which flows when said motor is locked, said method comprising the steps of:

  • placing a mode of said control circuit to a current-limiting value setting mode;

    displaying, on a display means, a detected current value of said motor while said motor is in locked condition;

    operating an up/down adjusting means which, with an accelerator operated fully, increases or decreases a duty-cycle of a current applied to said motor so that said detected current value displayed on said means represents a predetermined current-limiting value; and

    storing said duty-cycle of said current in a memory means, wherein said mode of said control circuit is placed in an effective current display mode when said detected current value is approximately equal to said predetermined current-limiting value.
