A sleek, futuristic single-wheeled motorcycle with a human rider crouched inside a massive gyroscopic wheel, speeding through rain-slicked neon-lit city streets at night. The vehicle features an enclosed spherical cockpit surrounded by a giant rotating outer ring, glowing with cyan energy lines. The rider wears a streamlined helmet, leaning forward in an aerodynamic pose. Reflections of pink and purple city lights shimmer on wet asphalt. Steam rises from street grates. Towering holographic advertisements blur in the background. Shot from a low dramatic angle emphasizing speed and motion blur. Cyberpunk style with high contrast lighting, chrome surfaces, and atmospheric fog.
