[RobinM1]

The Robin M1 has it's own patents. And to go into more depth on that one as well. Wheels, tires, windshields, etc ets. are part of every vehicle, not just one particular make. Taken a step further. All cars and truck have engines, those engines all have many components that make them run, and there pretty much all the same far as powering a car.....pistons that move back and forth inside a block to produce energy. The same thing goes with the Robin, the robin has it's own Computer Controlled Gyro system to keep balance, so there are no patent infringements.
