This 70's chopper bike started from a tutorial about the anisotropic node for cycles. I made the brake disk, and kept going-not sparing a single vertex!
I ended up using hands for some of the details like the sissy bars and to hold the spark plug wires from getting into the main drive belt. The bike is gold, chrome, and flaky green (thank you meta-androcto for the car paint). It has spoke rims with old style treads (mesh) tires, ape hanger handle bars and a surprise holding them that sums up the 70's in some ways.
There are a ton of previews on my web page http://zelozelos.ml and you should see it right at the top, but if its been a while, it will be down a little further. After you click on it it will take you to a whole page with images, pd3 windows and some info about it.
You will need 2 textures for it. 1st you will need a hdri mirror ball image for the world' environment texture. And then you will need a head lamp texture. The one I used was of an old round head light bulb's front that probably came from the 70's.
