TULSA, Oklahoma - Hundreds of bicycles will brighten the holiday for kids in Green Country.

It took four big trucks to deliver 220 bikes to Tulsa's Family and Children's Services Monday.

They'll end up under the trees for children who may not have a gift this Christmas.

"Their families have economic challenges, but there's also kids who have been through divorce or abuse, some trauma in their life, and so having something like a bike, it's just a little bit of happiness. And that can make all the difference in recovery and better functioning in just the rest of their lives," said Tina Wells.

The bicycles were donated by Tulsa's "Bikes for Tykes," which also supplies new helmets with every bike it delivers.
