I acquired a pair of old folders for something to do during this lazy summer. The previous owners re-painted them so there are no signs of any decal, brands, or lettering. The only thing that shows something is the rear coaster hub. It is Shimano CB-E110. They still have both front and rear caliper brakes.
The only difference between the man's and woman's is the length of the seatpost.
I am attaching a few photos. It is a rainy day so the pictures are not that great inside the garage. The handlebar also has a quick release type of hinge to rotate it up or down.
My gut feeling is that these are some kind of Asian knockoffs of certain euro folders but I could be wrong.
