Some online research implies that your wheelset uses relabeled "Formula" brand hubs. Their flip flop hubs have threads at both ends and no built in freewheel mechanism. A track (fixie) cog and a lockring go on the end with a small step in the threading. A single speed freewheel goes on the other end.
(I'd've posted a link, but couldn't find a definitive link to Formula products!)
It isn't a big deal 'cause single speed freewheels are cheap!
