Act as a visionary urban mobility designer with 10+ years of experience in sustainable transportation. Design a futuristic bike-sharing system featuring sleek, self-balancing cycles that integrate seamlessly into smart cities. The bikes should have [MODULAR BATTERY SWAPPING], [AUGMENTED REALITY NAVIGATION], and [AUTOMATED MAINTENANCE DRONES]. Describe the aesthetic: matte black frames with neon blue accents, lightweight carbon-fiber construction, and holographic displays. The docking stations should be solar-powered and equipped with [BIOMETRIC ACCESS], [WEATHER-PROOF CHARGING PORTS], and [AI-POWERED DEMAND PREDICTION]. The scene should depict a bustling cityscape at dusk, with the bikes glowing softly as they move in sync with traffic. Use a cyberpunk-inspired art style with high contrast and vibrant lighting to emphasize the cutting-edge technology.
