Jack the Bike Man Hairston in the charity's massive warehouse of bikes that are rebuilt and given to those in need

When some guys retire they like to spend their days playing golf. Not Jack Hairston. He likes to give away bikes. Not just a few of them, but thousands of them. To needy kids and their families.

"I just wanted to make the community a little bit better," he says, and adds "What else would I be doing?"

At the age of 75, Jack "The Bike Man" will be at it again this holiday season.

His bicycle giveaway is an annual spectacle in West Palm Beach, Fla., that attracts hundreds of families every year. From his enormous warehouse with the giant bicycle mural painted on the front, he and a dedicated team of volunteers distribute recycled bicycles to at-need children of all ages. This is an event that really can make a big difference for a child or family without a bike.
