A variable-structure self-balancing two-wheeled vehicle is integrally of a symmetrical structure, and is provided with a vehicle body device, a driving device, a steering handlebar device and an electronic control device. The vehicle body comprises saddles, a manned pedal and vertical plates, wherein the saddles are in bilateral symmetry, the middle of the manned pedal is low, and the vertical plates are used for fixedly and integrally connecting the saddles with the manned pedal. The saddles and the pedal are hollow boxes for holding the driving device and the electronic control device respectively. The driving device comprises two wheel carriers, wheels, four driving motors, storage batteries and driving gears for the wheel carriers and the wheels, wherein the four driving motors are used for providing power for the wheel carriers and the wheels respectively and are controlled by the electronic control device. The steering handlebar device comprises a steering handlebar base, steering handlebars, a coil spring, a steering handlebar motor and a main control panel, and the electronic control device consists of a main control circuit, a plurality of different sensors, an electroniccontrol power source and control circuits for the sensors. The variable-structure self-balancing two-wheeled vehicle has the advantages that a plurality of driving motors are controlled by a computerand by means of digital technology, the vehicle can be driven in the front, back, left and right directions, the driving directions can be switched during driving, and the variable-structure self-balancing two-wheeled vehicle is multifunctional, flexible in operation and convenient in driving.
