Mas Contractor, owner of the non-profit Bike4Life bicycle shop in Logan Square, learned long ago the power of helping others.

“My grandfather used to always say you need to help one person in the world,” Contractor said. “If you can help one person, then you did your deed.”

Two years ago, Contractor and a group of fellow cyclists decided to do some good deeds for the homeless.

On a recent Saturday, more than 100 cyclists volunteered to deliver food to homeless people in some 20 locations around the city.
