This power point was presented on the 2012 velomobile summerlab (Link to the original keynote version). It gives some info about how I started, why plywood is an interesting material and detail pictures of the proto.
The rear wheel with Rohloff hub is mounted directly to the body. The front wheels are suspended with a Mc Pherson linkage.

This post describes the mass distribution of the prototype. I think we can loose some extra kilo grams. The McPherson struts have a wall strength of 2.5 to 5 mm now. Can be less. Maybe someone comes up with a nice deux chevaux like front wheel suspension. The plywood thickness could be reduced to 1 mm. There is an aluminium tube at the sheet edges on top and at the foot hole. These tubes measure 22x1.5 mm. The foot hole should be eliminated. The size of the opening at the top should be decreased and maybe the tube can be reduced to 20x1 mm.
