There are many threads for lovely clean best bikes, with cranks nicely aligned with frame tubes, valves at 12 or 6 o'clock, marmite in the kitchen etc - very nice they are too. This thread is for beaters, filthy commuting bikes, mismatched components, bikes built from the spares box, nice bikes disguised through uglification, Mad Max styled bikes, basically bikes you like to ride even though conventional wisdom says they look rubbish. I think there's a certain appeal to this kind of bike.
Here's my Langster. I didn't like the zebra look of the paint job, but I did want a black bike. Preferably matt black. That didn't look flashy, because it's going to get locked up everywhere. So I got to work with tape and inner tube.
Now it's starting the mis-matched components phase, because black wasn't available, but blue was and was cheap.
This is how it might have otherwised looked:
