CanUgan Disability Support Project

Uganda is home to five million people with disabilities, whether from birth defects, malnutrition, disease or injuries sustained during the violence-wracked internal conflicts. Whatever the cause, Ugandans without the use of their legs have, in the past, been unable to use bicycles. And as Uganda is one of the poorest countries on this Earth, the bicycle is a crucially important method of transportation there. Without it, some cannot earn a living.
