Seeing this picture from a magazine got me thinking about an aerodynamic version of this. put on a full fairing and reshape the cargo area to be more aerodynamic.
I have seen many bicycles with full fairings before but this has advantages those don't. Bicycles with full fairings are not very practical for much other then racing. The cargo area is great for caring more then you could with a normal bike and yes I know you can get a bike trailer. The fact that it is a trike also makes it easier to carry more weight.
You could easily make it into an electric bike with all the room for batteries and other components in the cargo area.
