This SVG code creates a simple illustration of a pelican with a bicycle. The pelican's body is represented by brown ovals, and the bicycle is depicted using black lines for the frame, handlebars, and wheels. The eyes and some details are added with white circles and paths. You can adjust the `viewBox`, dimensions, and colors to fit your specific needs.
