...Very interesting bike, I'd like to know more about it.
I still owe you some info. (I took this info from a brochure): the bikes are called "the well-being Columbus Bicycle" by EZ-up and comes in different models. Folded size is 36x50x79. It folds 2-way ("horizontal and vertical") and when folded the bike can be used as a cart on its wheels and additional roller wheels. Weight depending on specs is between 12,8 kg and 13,8 kg. Gearing: Single speed or automatic internal 2 speed hub gear or 3Spd. Braking: V-brakes , on the 12inch model "band brake" in the rear.
look how the pedal folds and the strange curved cranks they had on one, here pics:
