Pimping up your bike is half the fun really - once you got the components together to make it into a bike in the first place of course. You can go extreme and colour-coordinate everything or you can just add a few touches that make the bike stand out. Here are some great examples of what people have got up to:

Anders Bruun Andersen's Daccordi

Bryan Kraft's Miyata

Bill Palladino's Coppi - that splits into two!

Branden's Cannondale - stripped, sanded and handpolished

Charles' Moth

Alex Vermeulen's Raleigh

Timothy Keen's Fuji Regis
