Fairing Reduces Windchill
Latest photos. The fairing and Tailbox are made of Coroplast (corrugated polypropylene plastic). The handlebars are BMX because I can’t assume a crouch position, it’s my neck vertebrae. So therefore I can’t mass produce these fairings, they won’t fit any other bike. It is custom fit to install on this bike.
For windchill reduction, I have added extensions on the handlebar nacelles. They each have one stainless steel machine screw, and the edges sealed with blue masking tape . No need to add lots of screws, in fact I think it’s better if they rip loose in a collision, and flop around hanging by the one screw. Masking tape is cheap.
Haven’t installed the studded tires yet, I’m going to wait and see what the weather does. I have installed Tannus Armour on both wheels.
The cargo space is very small on this bike, I have other cargo bikes, based on the same parameters and construction techniques. I consider this my touring bike.
The LED Lights are also a key feature of my creations. I’ve recently upgraded to motorcycle headlights and LiFePO4 batteries. I had been using lead/acid from 1986 until three weeks ago!
I’ve decided I’m not going to start a business making fairings. It was a student project for engineering school. My fairings suit my riding habits and local conditions. You certainly would not need windchill protection in the equatorial regions of the planet. It would be suicidal to ride without good LED lighting in New York City.
Yes, I keep the design very boxy. Molded curved plastic would require expensive molds. So flat plastic board is used. For the record, the angle of the front surfaces is less than 54° , and the trailing angle of the tailbox is 11°, 5° or 6° on each side. Really the edges should be curved. Feel free to make your own, it’s a DIY project. I can’t sue anyone for patent infringement.

I used a Zzipper fairing for years in Michigan and Seattle. In cold weather, that simple fairing = a full layer of clothes. Also a tooth on a fix gear cog (though I didn't change because the hills stayed the same).

I wanted something with cargo space, electrical dashboard, solid colors, LED lighting, solar panels,and angular lines, that’s why I built my own. Also I have mounting points for a rain canopy.

Yes, that’s my experience. The fairing helps riding in a higher gear. Amazingly the Tailbox added a 6MPH increase in speed. But it’s the front fairing that reduces windchill. Would you buy another Zzipper or did you move south?

Nice work. My only concern would be with the use of masking tape. If it gets wet the whole thing might fall apart.

All I know is that I am a winter rider in Winnipeg and I want to leave here.

The inner nacelles are rugged, the outer nacelles are pinned by a 10-32 machine screw with a stainless wing nut, you can see in this picture.
The winter extensions are pinned by a 10-32 machine screw, only the edges are sealed with blue masking tape.
I like it like this, in the event of a sideswipe the masking tape will rip loose, but the pin will hold it together. It’s not perfect, but it’s also a DIY project that anyone can modify if they think they can do it better.

So this is why I’m so happy with Coroplast ™️ corrugated polypropylene!
Fiberglass fairings would cost fifty times more to make, not even counting the cost of the molds!
Fortunately , the discussion only involved what I would do with other peoples money, if they had been willing to lend it...
I knew Coroplast ™️ existed, but I didn’t know what it was called.
With the Internet, information is available that people would otherwise be unaware of (or tight lipped about).

Corrugated polypropylene marked up before folding, pannier/Tailbox for rear rack
Finished polypropylene pannier/Tailbox from plans above.
Alternate 16” cube version of Pannier/Tailbox
Now, having gotten past the difficult part, the rest is easy. The fairing for the rear of the bike fits a standard rear touring rack, so I don’t have to make my own hardware, or redesign the fairing for every make, model, colors, and handlebars style of every bike on the market.
Here is the e-bike with the Fairing/Pannier system parked on a marble floor
It turns out that equipping the bike with LED lights costs more than equipping it with plastic.
Well , I’ve got one bad ass ride. See you around.
