They have Kilos in lots of different colors. If you want a bike with crazy colors and decent components though you'd have to build one yourself.

OR... the EighthInch Scrambler is a decent bike and might be just the thing for you. Kind of pricey for what it is, but you are also paying for the color customization. I think you'd end up paying around the same price if you were to build one up with similar-quality components.
