Creating a detailed SVG image of a pelican riding a bicycle involves several steps, including designing the pelican, the bicycle, and how they interact. Since I can't directly create or display images, I'll guide you through creating a simple version of such an SVG using descriptive markup. You can then use this markup in any SVG-compatible environment to visualize the image.

### SVG Markup for a Pelican Riding a Bicycle

```xml
<svg width="600" height="400" xmlns="http://www.w3.org/2000/svg">
  <!-- Background -->
  <rect width="100%" height="100%" fill="skyblue"/>

  <!-- Pelican -->
  <g transform="translate(50, 50) scale(0.5)">
    <!-- Body -->
    <circle cx="0" cy="0" r="40" fill="#8B4513"/>
    <!-- Head -->
    <circle cx="0" cy="-15" r="10" fill="#FFFFFF"/>
    <!-- Wings -->
    <path d="M -30, 10 L 30, 10 L 0, -20 Z" fill="#8B4513"/>
    <!-- Beak -->
    <path d="M 0, -20 L 10, -35 L -10, -35 Z" fill="#8B4513"/>
    <!-- Eyes -->
    <circle cx="0" cy="-25" r="2" fill="#000"/>
    <circle cx="-5" cy="-30" r="2" fill="#000"/>
  </g>

  <!-- Bicycle -->
  <g transform="translate(300, 150)">
    <!-- Frame -->
    <rect x="-30" y="-20" width="60" height="40" fill="#F5DEB3"/>
    <!-- Seat -->
    <rect x="-30" y="-40" width="60" height="20" fill="#FFFFFF"/>
    <!-- Wheels -->
    <circle cx="-30" cy="-30" r="10" fill="#8B4513"/>
    <circle cx="0" cy="-30" r="10" fill="#8B4513"/>
  </g>

  <!-- Bicycle Handlebars -->
  <path d="M 300, 200 L 330, 120" stroke="#8B4513" stroke-width="5" fill="none"/>

  <!-- Bicycle Pedals -->
  <circle cx="310" cy="160" r="10" fill="#8B4513"/>
  <circle cx="290" cy="160" r="10" fill="#8B4513"/>
</svg>
```

### How to Use This SVG

1. **Copy the Code**: Select and copy the entire SVG code provided above.
2. **Paste into an Editor**: Open any text editor and paste the code. Save the file with a `.svg` extension, for example, `pelican_bicycle.svg`.
3. **Open in a Browser or SVG Viewer**: You can open this file directly in a web browser or use any SVG-compatible image viewer to see the rendered image.

### Notes

- The design is quite basic and stylized for simplicity. You can enhance it by adding more details, adjusting colors, or scaling elements to better fit your vision.
- The `transform` attribute is used to position the pelican and bicycle within the SVG canvas. Adjust the `translate` values to change their placement.
- Feel free to modify the shapes, colors, and sizes to better match your idea of a pelican riding a bicycle.

This guide provides a starting point. SVG allows for a lot of customization, so you can experiment with different shapes, paths, and styles to create a more realistic or stylized image.
