Good point. I went back to the pictures Catrin originally posted of the bike to get the bigger picture. Oakleaf is right that the stem is awfully short. Your bars are also high relative to your saddle. Was that a conscious decision on your part?

If you'd let me, I wouldn't mind riding the bike myself for a few minutes to get a feel for it.
