MickPolly, an owner of a toy store, lives with his teenage daughter Carolina inKentucky. He is known as the Bike Man. Over the past five years, Mick has builthundreds of bikes for needy kids.

Oneday in 2012, a 13-year-old boy with a broken bike walked by Mick\'s house. \"Iwas working in my garage(车库); and he asked if I couldfix it,\" says Mick, now 53.

Theboy\'s bike had a broken wheel. Mick sent a post(帖子)on Facebook, asking his friends if they had the needed part. One friend saw thepost and gave away two used bikes. Mick took parts from each to build a new setof wheels for the boy.

Soonafter, Mick repaired a bike for the boy\'s brother and fixed one for his sister.Word spread, and during the year, he had fixed up lots of bikes for local kidswhose parents were not able to afford new ones.

\"People are throwing away bikes day and night,\" says Mick.

Mickputs the bikes and bike parts in his garage. \"I take off the good tires orthe handlebars or the seats and use them,\" he says.

Up tonow, the bike man has repaired hundreds of bikes and given away nearly 700newly repaired bikes. They\'re free, but the kids must agree on two things: Theyhave to learn how to put waste things to good use and they have to try theirbest to study in school.

If akid\'s grades are low, Mick requires a teacher\'s note \"saying that you\'redoing your best\". Mick also hopes the bikes will get kids off the sofa. \"WhenI was growing up, we all rode our bikes,\" he says. \"Hopefully thesekids can get some exercise.\"
