The Superconductive Linear Motorcycle (超電導リニア二輪 Chōdendō Rinia Niwa?, lit. "Superconductive Maglev Two-wheeler") is apparently a famous two-wheeled vehicle in Academy City. According to Itsuwa, the vehicle is said to have donut-shaped wheels, and that they and the axles are held together by magnets, letting the wheel pass through the motor gas and run.[1]
