There's going to be a big bikeathon in Busytown to raise money for charity, and Billy wants to raise a lot of money. Except when Billy's bike is run over it looks like he's out of the game, unless he can earn enough money to buy a second hand bike. As the big day approaches, Billy keeps track of his savings, but he's still short. And that's when to his great surprise, all his friends chip in and Billy gets that bike. Boy... it sure is nice being able to count on your friends.
