Here's an example of what the requested SVG code might look like:

```xml
<svg width="400" height="300">
  <rect x="0" y="-100" width="200" height="50"
    fill="#f5a9b2"/>
  
  <!-- Pelican head -->
  <circle cx="40" cy="70" r="20" 
          stroke-width="4" stroke="#333c8d" fill-opacity=".7">    
      <desc>Pelican</desc>
   </circle>

  <!-- Wings (using mask for opacity)-->
  <mask id="wingMask1"
         data='url("#")'
        >
       <use href='#wings'>
           <div class = 'opacity-30'></div></use>
     </mask>
     
      
  <rect x="-100%" y="%50" width ="200% height= "25%
    clip-path: url('#wingMask2')">
  
<!-- Winger -->
<svg xmlns="http://www.w3.org/1999/xhtml
vector"><polygon points="
          -10,0 
          20,-40   
          -80 ,60 "
      fill="#333c8d"/></svg>

 <!-- Bicycle frame (simplified)-->
<g transform='rotate(45 120,140)' stroke-width=".5px"
        mask="url(#frame)">
   <circle cx = '150' cy ='170'
           r ='30'/>
</g>
      
     
     </rect> 

 -- Frame of bicycle -->

       
    //Frame details

       rectangle x="-100%" y="%50" width ="200% height= "25%
    
<!--Handle -->
<use href='#handle'></use></mask><text
         text-anchor='.5'>Pelican Rides!</text>"
          font-family="'Arial', sans-serif">
          
      <!-- Handle position (x,y)-->
<g transform='rotate(45 120,140)' fill="#333c8d"
        stroke-width=".4px">   
   <line 
     start="0,-10" end = "-20 ,40"/>
</g>
      
     
 </svg>  
```

Please note that this is a simplified representation and may not perfectly depict the actual appearance of pelicans riding bicycles. The SVG code uses various shapes to create visual elements like circles for body parts, rectangles or polygons representing bicycle frames using masks with opacity effects.

You can customize it further by adjusting colors, sizes etc., as per your requirements!
