The bike needed to be easy to build and easy to get off of when fully loaded, (some people do not understand the need for a low step through frame); and sitting up straight is needed for carpal tunnel syndrome.
And the design must be original!
These should to be community projects, not entrepreneurial projects.
I am not interested in helping the bicycle industry improve their machines. Capitalism will never give you a good product for a good price because they have to make it as cheaply as possible to make the largest possible profit.
Actually I do not expect anyone to do better. Because it took me years to learn how to construct a bicycle from used bikes, without a shop.
Based on this design concept, I have another winner
I do like leaning trikes and other cargo bikes, but not for ease of construction.
I like the idea of using a Nuvinci hub gear with a motor. So that it is easy to match the pedaling with the motor speed.

boxes front and rear, vertical sitting position, and disc brakes,
and most important a two stage gear box driving the left side of the wheel.
