An ambitious bike thief thought he was going to make a clean getaway, until he saw another bike in his stolen side mirror. The victim's best-friend turned vigilante hopped on his own bike and chased down the scumbag. From his helmet cam we see the hero quickly close the distance. As soon as he's close enough, the avenging rider kicks the bike out from underneath the fleeing crook. The cops arrive a few minutes later to throw some handcuffs on the battered and bruised perp.
