I found this image searching Google while preparing my post about Ashley Gilbertson's book. It's from a photo-sharing site in an album maintained by a Marine photo journalist, Staff Sergeant Chad McMeen. This is the photographer's own caption:
This Marine customized his bicycle beyone the point most are capable of. By extending the front forks and welding the rear swingarm in a lower angle he was able to position himself feet above the ground. Somehow with a backpack, bulky jacket and rifle slung across his body he managed to mount the bike and ride effortless.
