I understand your bike was stolen but I think most bike thieves steal in order to sell. In other words, maybe you're victimizing someone else who bought you're bike from a thief, unknowingly. Honestly it's rough, when you're in the market for a used bike, to know exactly where it came from. Just don't assume. Investigate before you do something rash or else, in the end, you'll be the one feeling like a criminal. Good Luck.
