The invention discloses a double-shaft rear-single-wheel drive electric automobile which comprises a frame, two front steering wheels, a rear drive wheel and an electromotor. The two front steering wheels are arranged at the front end of the frame, the rear drive wheel is arranged at the rear end of the frame through a rear bottom fork, and the electromotor drives the rear drive wheel through chain transmission. By the adoption of rear-single-wheel drive, the rolling resistance of the automobile is reduced when the wheels make contact with the ground, an assembly of a transmission and a differential mechanism of a traditional automobile is omitted, the whole mass of the automobile is reduced, consumption of an automobile-mounted battery is reduced, and runtime of the automobile is greatly prolonged. A lengthened lever connected with a shock absorber is arranged, the connecting position between the shock absorber and the lengthened lever is adjusted, the double-shaft rear-single-wheel drive electric automobile can be suitable for different road conditions, the drive wheel can be kept to be tightly attached to the road surface when the automobile is under the various road conditions, enough drive force is acquired, the method is simple, cost is low, weight is low, and the design strength requirements are met.
