The anonymous vigilante now scours Craigslist, OfferUp, and other dens of villainy for suspicious bikes, then cross-references them with ones reported stolen on Bike Index. It's a time-consuming task, since Seattle has tons of bikes, tons of drugs, and therefore tons of bike theft. Once he gets a match, he asks the seller to meet up ... which doesn't always go so well. One time, the thief recognized him from a previous incident and brought four pals, forcing Bike Batman to flee the scene. That episode probably explains why the two-wheeled crusader has started coordinating his stings with the police beforehand.
He's not alone. Snow removal worker Floyd Hall devotes four to six hours a day to snooping Facebook pages on stolen cars and digging through his tip-inundated inbox.
