If you visit the Orange County Chopper website, you can use their online interface to design your own chopper, complete with a full-color “photo” of what your bike would look like. Choose from a variety of chassis designs, tanks, fenders, wheels, etc. Add your own graphics (although right now the only choices are flames or no flames) and select your own paint color.
When you’re done, you can add a background and see the bike you’ve just designed. Fill out the form attached, and they’ll send you a quote so you can see what your bike will cost.
