@rod1148 seems like the coroplastic would need some kind of support structure. I was thinkng of making triagular pipe with the coroplastic and then taping/gluing it to the fairing for added structural support.
Just a tiny bit squirrley ... mostly when there was a heavy cross-wind. Love those days with a tail-wind though! I have converted this fairing into a yard-wagon for leaves and the like and will be building a different design this fall. I am hoping to try something more V-shaped to see if it cuts down on wind-resistance better.
Yep, I am real cheap. But it worked for awhile. Then I needed something to move dirt from the front yard to the back yard. The fairing worked great. Now I am going to design a new one ... thinner at the front.
I am in the process of designing a new one I was surprised by how little structural support the coroplast needed. The support came from the handlebars and also the fender posts. The rest of the support was from the angle of cuts and folding.
@lhtrees would like more details on your fairing design and mounting system. I have a bikeE and have been working on some designs using coroplastic board. Also designing a full surround skin, with either the coroplas or stretch fabric or plastic.
I built a similar coroplast fairing for my BikeE a few years ago. A road it a couple of times but found the handling to be a bit squirrley. Seemed like the center of gravity for the steering was pushed to far forward. Have you had that experience? I took mine off after a riding only a short time.
@NASIRUB1 it can even get cheaper by scanenge the real estate for sale/open house signs that real estate agents/broker leave out as litter on the streets.
