The boy, Leo, treasures his bicycle so much he gives it a name--Big Red. But eventually Leo outgrows Big Red, and this is where the bicycle's story takes a turn from the everyday, because Leo decides to donate it to an organization that ships bicycles to Africa. Big Red is sent to Burkina Faso, in West Africa, where it finds a home with Alisetta, who uses it to gain quicker access to her family's sorghum field and to the market. Then, over time, it finds its way to a young woman named Haridata, who has a new purpose for the bicycle--renamed Le Grand Rouge--delivering medications and bringing sick people to the hospital.
