Brief introduction of the invention: The invention creatively puts forward a new concept that the steering movement of two-wheeled motorcycle is synchronized between different shafts through mechanical transmission, so that the front wheel and handlebar can adjust the front and rear distance according to the design needs of the vehicle type, so that the design of the vehicle type is more in line with the principles of ergonomics and aerodynamics, and provides a necessary premise for perfecting the use function of the two-wheeled motorcycle and improving the driving posture. In addition, a design patent "Two-seater and Two-wheeled Motorcycle with Different Axle Steering" was introduced. The car has perfect streamlined shape, comfortable seats, complete windshield, foldable lifting roof, certain safety and anti-collision functions, and its cost is several hundred yuan higher than that of ordinary scooters. It is predicted that the development of this car will have a broad market demand and economic benefits of tens of billions of yuan.
