Picking out a present for a hobbyist is an easy thing to do. You just need to know his interest or hobby and get something that he can use. For a cyclist, for instance, a yakima bike rack will be sure to make him happy. Of course, you would have to check that he doesn't already have one. It is always good to do some checking beforehand so that your present would be useful to the recipient otherwise it would end up being clutter.
