Crack Bike 

A bike that was stolen and sold for well below it's original price by a crack cocaine addict so they can fund their drug habit.

Dude 1: Dude, I just bought this bike for $20 from that used bike store.

Dude 2: Yeah man, it's totally a crack bike. Apparently this hobo shows up everyday with a new one.
