Frame sketch

To make my idea of the planned plywood frame more comprehensible to You,
I have made a sketch.

It's rather crude, but understandable, I hope.
The cantilevering extensions of the middle box will take up the swingarms for the rear wheels.
These are placed off center to the red main beams, to provide maximum rear track and room between the wheels for childs/passengers on the back seat.
The geometry is the same as in the recent test frame.
