Most heroes are not super.They don't appear in comic books，on television，or in movies.They just do what they believe needs to be done to make their world a better place.Bike Batman is one of them.
   Bike Batman is a 30-year-old married engineer who lives in Seattle，Washington.He's a cyclist who also buys and sells bikes as a hobby.
   About three years ago，he was looking for a bike for his wife.He found one on Craigslist，a website where people list things they want to sell.As he often does，he also looked at Bike Index，a popular website that allows users to register their bikes and post reports when they're taken.The bike，which he was considering purchasing，clearly matched one reported stolen on Bike Index.
   Then he called the person who claimed（聲稱(chēng)） to be the bike's owner and arranged to meet him- supposedly to complete the sale.When the two men met，Bike Batman told the thief， "You've got two choices.You can wait until a police officer gets here，or you can just get out of here." You can imagine what the thief did.
   After that first success，Bike Batman developed a safer routine.When he sees questionable bike ads on Craigslist，he cross-references the image with bikes reported on Bike Index.Once he has confirmed it with the owner，he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action.In more than half of the 22 cases in which he has got back and returned bikes，the thieves have been caught.In one case，Bike Batman even helped a family recover a wide range of prized belongings that suspects（嫌疑犯）had stolen during a home burglary.
   His nickname came from a discussion with a police officer who suggested he be called "Robin Hood".Since he wasn't exactly stealing from the rich and giving to the poor， "Batman" seemed a better fit.The idea of a superhero punishing criminals feels pretty silly to him，but the main reason he continues his work is to keep up Seattle's fame as a friendly city.
