I was bikejacked once, when I used bike. And my mom saw the bike with a guy some weeks later (with others wheels and stuff). She recognized the mothafucka (she knew where his mother lived), and told him : "or you gimme the original bike in 30 minutes or I'll call police and talk with your mom (he was like 19 yo)". 30 minutes later, there was my little bike

That was on April 1st, I only believed in my mom when I saw the bike. I have the super-mother ! hehe
Good luck ace0r. And the police really sucks.
Now I just walk and metro.
