Fairing Reduces Windchill









Latest photos. The fairing and Tailbox are made of Coroplast (corrugated polypropylene plastic). The handlebars are BMX because I canít assume a crouch position, itís my neck vertebrae. So therefore I canít mass produce these fairings, they wonít 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 itís better if they rip loose in a collision, and flop around hanging by the one screw. Masking tape is cheap.
Havenít installed the studded tires yet, Iím 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. Iíve recently upgraded to motorcycle headlights and LiFePO4 batteries. I had been using lead/acid from 1986 until three weeks ago!

Iíve decided Iím 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 54į , and the trailing angle of the tailbox is 11į, 5į or 6į on each side. Really the edges should be curved. Feel free to make your own, itís a DIY project. I canít 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).

Yes, thatís my experience. The fairing helps riding in a higher gear. Amazingly the Tailbox added a 6MPH increase in speed. But itís the front fairing that reduces windchill. Would you buy another Zzipper or did you move south?
I wanted something with cargo space, electrical dashboard, solid colors, LED lighting, solar panels,and angular lines, thatís why I built my own. Also I have mounting points for a rain canopy.

I no longer commute, plus I've tapered off winter riding because crashes have bigger consequences than they used to. Also I've never really liked the brake hood attachment and loss of hand position. As someone who has studied a lot of aerodynamics, I love the Zzippers. That simple shape works very well.

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.
