The present invention discloses a double-bend double-girder structure for a scooter. A frame comprises a frame body; at a front end of the frame body, two girders arranged longitudinally in a front-rear direction, a mandrel arranged transversely in a left-right direction and fixed to the girders, and a tiller arranged vertically are provided; one shock absorber is fixed to each of left and right ends of the mandrel, and a lower end of the shock absorber is fixed to a front wheel bar, an outer end of which is fixed to a front wheel; and each of the girders consists of a front girder segment, a middle girder segment and a rear girder segment, the front girder segment being relatively located above the rear girder segment, and the middle girder segment being arranged between the front girder segment and the rear girder segment. The present invention has the advantages that the structural strength of the frame is increased, the concentration points of stress are reduced, the service life of the scooter is increased, the structure of the scooter frame is simplified, the stress distribution of the shock absorption system is optimized, and the comfort during the use of the scooter of the present invention is improved.
