I was having the same issue. If the script tag is referenced without specifying a version, the bicyclingLayer does not render. If you add &v=3.0 like william suggested, it renders.
Here is the script tag I am using now, which works as expected: <script type="text/javascript" src="http://maps.google.com/maps/api/js? sensor=false&v=3.0"></script> -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
