The invention relates to a car hopper for transporting shared bikes, and belongs to the field of shared bike maintenance equipment. The car hopper is composed of a rear baffle, a chassis, a front wheel trough, a first positioning rod, a second positioning rod, a front baffle, positioning holes, a clamping groove, a wheel trough, a spindle trough, a positioning frame, a limiting mechanism, a five-way trough and a rear wheel trough. The rear baffle is arranged on the left side of the chassis, the front baffle is arranged on the right side of the chassis, the positioning holes are formed in the front baffle and the rear baffle correspondingly, the first positioning rod and the second positioning rod are both matched with the positioning holes, the first half portion of the chassis is provided with the front wheel trough, and the second half portion of the chassis is provided with the rear wheel trough. According to the car hopper for transporting the shared bikes, the front wheel trough and the rear wheel trough which are alternatively distributed in the car hopper improve the space utilization rate, transportation of the shared bikes can be more effectively conducted, the stability of the shared bikes on the chassis can be effectively enhanced by arranging the limiting mechanism and the positioning frame, the structure of the car hopper is relatively ingenious, the transporting efficiency of the shared bikes can be effectively improved, and the labor intensity of people is relieved.
