I’m a massive fan of the TV show American Chopper. Mainly because I like seeing them conceptualise a bike and document the process of building it (not to mention building works of art in a week!).
I’m also a fan of the show Biker Build-off. Some of the custom shit they do is soooo inspiring. Blows my brain and makes me feel weak for buying off the shelf bolt on parts for my cars and bicycles.
Here are a couple of links to guys who put their heart into bikes they build:

Their work is to die for.
