Formatting data in dropdown box pulled from db?

Question

I have the following snippet of code:

<li>
    <label>Engine Size:</label>
    <select name="engine">
        <?php
        $sql = mysql_query("SELECT DISTINCT BikeEngine FROM bikes "
                . "ORDER BY BikeEngine ASC");
        while ($row = mysql_fetch_array($sql)) {
            echo "<option>" . $row['BikeEngine'] . "cc" . "</option>";
        }
        ?>
    </select>
</li>

My main issue is that the engine size is stored as an int in the database field but I want to add the cc on the end in the dropdown box as a suffix, but when the query is ran, it searches for say 1500cc and returns no results because it is stored as 1500 in the database field.

I was wondering how I'd go about resolving this?

Model:

public function searchBikes($brand, $engine)
{
    if ($engine=='Any' || $brandString=='Any')
    {
        $this->db->select('BikeEngine');
        $this->db->select('BikeMake');
        $query = $this->db->get('bikes');
    }

    else
    {
        $this->db->like('BikeEngine', $engine);
        $this->db->like('BikeMake', $brand);
    }

    $query = $this->db->get('bikes');
    return $query->result();
}

Controller:

function search() {
$this->load->helper(array('form', 'url')); //without this form will not display

if ($this->input->post())
{
    $brand = $this->input->post('brand');
    $engine = $this->input->post('engine');
    $this->load->model("mbikes");
    $data['results'] = $this->mbikes->searchBikes($brand, $engine);
    $this->load->view('searchresults.php', $data);
} 
else 
{
    $this->load->view('search.php'); //display success view
}
}

选项值可以与其显示不同：

echo "<option value=". $row['BikeEngine'] .">" . $row['BikeEngine'] . "cc" . "</option>";
