Comic-Book Heroine on a Bicycle

In a bold, high-contrast comic-book style, a beautiful White woman rides a sleek bicycle through a sunlit city street. Dynamic action pose, wind in her hair, flowing scarf, and a confident expression. Thick black ink outlines, dramatic halftone shading, and vivid primary colors. Slightly low, dynamic perspective with motion lines around spinning wheels to convey speed. Cityscape background with tall buildings, storefronts, and streetlamps. Retro-pulp vibe with speech bubble and caption box elements to emphasize action.
