Not sure if i'm completely through fiddling with it (especially the paint - i may redo it with better paint), but i'm pretty happy with my first ever single speed conversion. i pulled an old Huffy LeGrande 12 speed out of the trash. It was in pretty sorry shape, but i figured it was an excuse to give conversion a try. i tried to reuse as many parts as possible, to keep this on the cheap, but also in the name of recycling. After mangling the rear hub, after trying to get it apart and convert it, i broke down and bought a relatively cheap (around 50 bucks) rear wheel with a flip/flop hub (which came with a fixed cog) and a new 16T freewheel. I also invested in a new brake lever. Everything else is either original or taken from other bikes - special thanks to the BMX that a neighborhood kid abandoned from which i commandeered the chain ring.
I re-upholstered the seat using some leftover faux leather vinyl to give it an old school look, though it's harder to do than i thought and consequently the material is not as tight as i would have liked it. oh well.
overall i'm excited to ride it! Here are some before, during and after photos.
