Help me with DIY motorcycle fairing

Hey Guys,

Now that the electric motorcycle goes 45 mpg, I am really starting to feel the effects of wind. (Plus my wife doesn't like the rougher ride at that speed)

Please help me with some ideas on how I can make some sort of aerodynamic fairing for it to reduce wind resistance and gain economy.

I was reading through an old motorcycle book and found some cool photos of fairings on British race bikes.(Cool sidecar racing too) Those fairings completely covered the front tire.

Something like this:

I am a bit inspired by the aero-CRX with the use of flexible plastic pipe and fiberglass.

My dad has been working on building wood canoes, so he has plenty of fiberglass materials around for that. I know that one of the earliest salt-flats racing cars actually used an upside-down canoe as the car body!

Perhaps I could design something with bent flexible tubing, cover it with fabric, and then fiberglass that?

Recumbent bikes have had "bodysocks" available to them for a while: a fabric stretched around the windshield and frame to smooth out aerodynamcs.

In the end, it would be nice to have a very light, rigid shell that would entirely cover the cycle. Then I would redo the head and tail lights custom with LEDs designed to fit that shell.

I would also like to fit a little bit of cargo space onto the cycle. Having no storage other than a backpack is a bit limiting. Even when I slapped the pizza rack on the back of the bike, it really did suddenly make a lot more usable space.

Here are a few designs I like:

I had one of those light cycles as a kid. Wish I still had it!!!
