I saw this video on you tube and thought..."If only".
I doubt many people have the time, equipment and circumstances to be able to do this. I'm sure some people do, but it may take them months, even years, to finish the bike off.
For most of us life is too busy to be able to make a custom bicycle. I'd hazard a guess that life is also too expensive to be able to buy a custom bicycle like this.
I know I sound like I'm being hard on the people who do this sort of thing. Maybe I'm jealous or I don't have enough cash!
Either way, take a look at the video and I'm sure you'll agree that it looks pretty cool and a great use of scrap cars.
