The telescopic spring is fixedly connected to the outer side of the main shaft and fixedly connected with the fixing rings through the main shaft. The main shaft is embedded in the middle position of the beam frame. The fixing rings wrap the two ends of the main shaft fixedly. The fixing rings are arranged at the joints of the beam frame and the main shaft. The beam frame is arranged above the supporting band. The supporting feet comprise the movable bolts, the connecting rods, the sleeves and the bottom boards. The double-supporting-foot type bicycle frame is provided with the two supporting feet, so that a bicycle is more stable when stopped; and meanwhile, due to the movable bolts, the normal travel of the bicycle cannot be affected by the supporting feet, and the double-supporting-foot type bicycle frame is simple in structure, economical and practical.
