So I just found this on a motorcycle, has some interesting things built into it's shape.
Ecosse Spirit: Frameless Motorcycle from Bikes in the Fast Lane - Daily Motorcycle News
It says it has a Cd of about .4 and weighs 265 pounds. I feel that I can probably beat the Cd fairly easily by creating a bit of a tail and enclosing the front feel design, but I like how it's contoured around the rider. I don't think that I could beat their weight though but who knows.
For now I am going to plan on a Cd of .35 (which I can probably beat that but I need to be pessimistic for my battery sizing) and maybe 330 for the weight.
I'm going to guess that frontal area will be around 10 square feet, though it is probably lower, which will give us a CdA of 3.5.
