Cafe Press has some T shirts with 'Kona' on the front and decals, mugs, etc. with logos like 'Think, Live, Be Green...Kona' but they refer to the location for now, but once the Kona has been out longer, I imagine they'll have stuff with the vehicle featured. You can also submit a custom design or photo and they will print it on T shirts, although I've never done that, and can't vouch for the results.
