After thinking a bit (always dangerous) it seems that you need to know if the handlepost folds to the left side of the front wheel or to the right side of the front wheel. When the Tern Link C7 is folded (not an N-fold bike), the handlepost ends up inside/between the wheels. AFAIK, when any other Tern Link is folded, the handlepost ends up outside of the wheels. However, in both instances, the handlepost folds to the left of the front wheel. There are some models of Dahons where the handlepost folds to the right of the front wheel. On most of those models, the handlepost ends up outside of the wheels. I believe you will want an inside fold handlepost, but I will defer to Thor if his opinion differs from mine.
