The seat is unique to Rans and is derived from their recumbents. Basically you sit on it and pull down hard on the bars, particularly when pedaling uphill. Riding is stable and predictable and there is the added element of reassurance in that one can put both feet down when stopped while remaining seated.

A crank forward is not that long. And I expect the Mini Me to be good enough to be put in a car trunk once the wheels are removed.
