Hi bwientjes -
Just a couple suggestions: You might do better if you simply stated the fact that it's a 25" frame - and refrained from limiting your audience to "someone over 6'3" " - (While many people prefer bikes that are small - there are some who prefer slightly larger frames and who are not so tall.

Also - (and you will get varying opinions on this) if you are looking to get $200, I would list it for just $220. (Unless there is something wrong with the bike you should not have to discount it by any 25%. )
