This Flevo-variant of Andreas Leutz has a different rear suspension: A pneumatic gas cylinder. You can see it diagonally under the rear fork. The gas cylinder is connected to a pressure reservoir behind the seat.
On the picture, the bike is at it utmost recumbent position, but with one push on a button it can be tilted more upright.

This unnamed bike with Flevo-like steering can be moved up and down while riding. This way, the rider can change between a pretty upright and a recumbent posture.
The rear wheel contains a modificated 7 gear hub, with some 3 speed hub parts in it. Under the frame is a steel cable which is wound around a drum. This drum has replaced the chain gear-wheel of the rear hub.
A handle can switch the rear hub in such a way that the steel cable can be wound or unwound. This mechanism is powered by the riding rear wheel.
Detail: A special mechanism keeps the luggage carrier always horizontal. The headlight has not (yet) such a mechanism...
