Ooooh that's a tough one! I think guys are the hardest to shop/scrap for! You think he'd pose for one like this?....

LOL probably not but if he complains then you can say "Hey at least you didn't have to..."
Not that there is anything wrong with that LO (actually it is fantastic, which is why it was published) but most guys I know would give you a look if you wanted to take a picture like that.
Maybe you could do a collage of pics of him with his bike, and then some wordart over the top. Sorry I can't be much more help!
