The invention discloses a height-adjustable balance wheel structure. The height-adjustable balance wheel structure comprises a bearing block, a balance wheel supporting seat, a left balance wheel supporting plate, a right balance wheel supporting plate, a balance wheel assembly and a screw; the upper end of the balance wheel supporting seat is cylindrical, a bearing is arranged between the cylindrical part and the bearing block, and the balance wheel supporting seat is capable of rotating relatively to the bearing block; the lower end of the balance wheel supporting seat is crescent and 5 first through holes penetrating left and right are formed in the crescent; the left balance wheel supporting plate and the right balance wheel supporting plate are symmetrically arranged on the two sides of the crescent of the balance wheel supporting seat, and second through hole eccentric away from the first through holes are formed in the rear ends of the two balance wheel supporting plates; the screw orderly penetrates through the left balance wheel supporting plate, the balance wheel assembly and the right balance wheel supporting plate and is locked by use of a nut. According to the height-adjustable balance wheel structure, when the balance wheel assembly is worn down to a certain extent, the balance wheel is adjusted to a proper mounting height by virtue of the eccentricity of the first through holes and the second through holes so as to guarantee that the driveability of the whole vehicle is not affected.
