This badass chopper was (apparently) hand-built by Emile, a Frenchman whose Citroen car broke down in the middle of the northwestern African desert, and who built himself a motorcycle out of the parts, without any tools. Here's the Imgur gallery, and an accompanying Reddit thread. There's a Hack-A-Day has a rough translation from Chameaudacier's site:
While traveling through the desert somewhere in north west Africa in his Citroen 2CV , [Emile] is stopped, and told not to go any further due to some military conflicts in the area. Not wanting to actually listen to this advice, he decides to loop around, through the desert, to circumvent this roadblock.
After a while of treading off the beaten path, [Emile] manages to snap a swing arm on his vehicle, leaving him stranded. He decided that the best course of action was to disassemble his vehicle and construct a motorcycle from the parts. This feat would be impressive on its own, but remember, he’s still in the desert and un-prepared. If we’re reading this correctly, he managed to drill holes by bending metal and sawing at it, then un-bending it to be flat again.
It takes him twelve days to construct this thing. There are more pictures on the site, you simply have to go look at it. Feel free to translate the labels and post them in the comments.
