Whether walking to get the mail, biking to school or work, or simply walking or biking around the block, many of us are pedestrians or bicyclists at some point during our day.If you are an individual with a bicycle or two, or bicycle parts and accessories to donate for repair, reuse and recycling, it is usually most practical and cost effective to donate them to a local program.In some areas you have a choice of directing you bike to an organization that will use it internationally or to a domestic program.
