There is a body of previous work. The Girl who designed the TYPE NINE , in the process of creating a LADIES VERSION of the Bike, changed the Design in such a way, that it was thought impossible to add a Roof again. I had to re-evaluate her Design, and bring back items from the previous TYPE SIX.

I would suggest that the nose be narrower more like Type 9. A prone delta velomobile has potential for low cost and low drag with lots of cargo room. Don't let the "That ain't it" gang stop you from doing your homework and coming up with sound designs.

Yes, the sides could curve in, to a narrower nose.

It´s all been done before (late 1980s, that is).

We have not seen that in Google searches this side of the Atlantic. Thanks. I have a similar design under construction.
For a prone bike I dragged out some 20" frames and the rear section of an adult trike. The bottom bracket height would be about 9" and the trike frame is 30" wide. My inseam is 30" and my torso is 19" so I would use a 30 degree hip angle. Support at the hips and shoulders would leave the stomach free for breathing. My upper arm is about 9" and my home made aero bars are 14" long mounted 10" apart on a flat bar. Width at the shoulders is 20". A nice size enclosure under the chest and the basket in the rear combined would handle 8 bags of groceries. Cut the frame top and down tubes and insert a sturdy box structure. My eye height would be at about 40". The shell could be based on the Poisson (fish) curve profile. See ecomodder.com Template C or Joseph Katz 'Race Car Aerodynamics: Designing for Speed' (1995) pg 48 Fig. 2.21 example 5. Think Sunracer meets B-2.
Side note: I was going through my father's service records so he could be buried in a national cemetery. During the late 1940's he was an ADEAN on the USS Kearsarge.

Hey Av', don't forget to include a massive two point kickstand, as it makes it much more convenient when loading and unloading massive loads of groceries. The design you're proposing is a lot like a no welding shopping bike I cooked up with 2 foot square wire baskets front an back. I built a swing down kick stand on the back edge of the rear basket out of hockey stick shafts. No cab on it, but it has a golf umbrella for rain protection. A Fred Flintstone type of project, I went free form with multiple colors of left over spray paint and went "Jackson Pollack" throwing on splatters. Come to think about it, I could add a coroplas body quite easily to my bike with some ty-wraps and duck tape.

Definitely a good idea for a two wheeler. Coroplast works well with zip ties and 2" Gorilla tape.

Is this the same machine , that Ivo.M showed us?

No, wait, it has bulge-pods, for a wider set of handlebars, and a different ladies-bike underneath... has to be a ladies bike, or else you can't swing your leg over to easily... I was lucky , I found a 20 inch wheel , six speed bike in 1986, , but that design was never repeated, so I can't use the fairing design, so it had it's drawbacks...

I could make a fairing with a low roof, only high enough for a racer in "tuck" position, but I think it would be awfully uncomfortable... unless maybe the top lifts up like a sun-roof, or the hatch on a recumbent velomobile...

I will probably use THIS bike, which is only one speed, and the left pannier is deeper than the right:

I find the Fiberglass Seat to be comfortable, and if I crouch down, to get my face behind the Fairing, I can move my big Butt back - far enough - that my face does Not impinge the Windshield... As this is Fiberglass, 7 layers thick, using tape with a good selvage , to keep it from fraying while I work< I have avoided the need to buy a Tig Welder:

I have decided to hinge the upper section of the tail box at the rear 18" from the seat to allow for putting a leg over. I have switched to a step through frame because of stiffness in my hips. Bar end grips can be used like clip on bars on a motorcycle. I have a 5 spd 20+ inch wheel so a 14-28T freewheel matched with 50/40T chain rings should let me have a top speed of 18 mph.
I found that stopping the fairing just below the knee to work well. It may have less drag and is much easier to put a foot down.

That's great. But which do you prefer? Step Thru or swinging your leg over? Or you keep the option of both?

The 1:4 scale model has been crated, and put in storage. I have too much other stuff to work on...

This guy copied a stealth bomber or something. Good thing he's wearing socks and sandals, you wouldn't want sweaty feet while riding that thing (how would you stretch to reach between your toes?):

Right now it's step through for me until I loosen up my hips but I design for both. The duct tape special could put the disc wheel cover on the rear and use some HED style aero on the front rims. I let my nose piece come down to the joint of the head tube and down tube then continue back to the leg just below the knee. The tail section tucks in behind the upper leg at about 30 degrees. I have noted in tuft tests a lot of turbulence around the brake assembly.
The weather protection domes would likely catch air without side panels. Believe it or not I like rubber barn boots in wet weather. The shape is oval from the ankle up too. My old Campmor chaps are almost worn out so I need to make some new ones out of tarp material and a nylon liner. I'll use velcro instead of tie strings at the top and snaps at the bottom.

Yes, much too large. Quicker to go to https://ibb.co/album/cmsk8v and select a photo. Thanks for posting them.

This seems a better design of all especially on standing against weather and wind. I'm planning to do this kind of design right after we finished installing the Moto metal wheels on the current truck project.

See the BMW C-1 scooter for a similar configuration. The area behind the rider would be closed off to reduce drag.

Nevermind the BMW C-1 ... I scored some photos yesterday of the PIAGGIO MP3 !!!

Check out the Windshield... very similar in *Dimensions* to what I built... I believe this will keep 90% of the rain off of the rider...
