This is the one of the main means of transport of most goods that are sold in the markets in Goma and the rest of the region. Men load up bicycles or wooden carts with huge loads of vegetables, maize, beans, charcoal, whatever. Their strength is amazing. Some people actually ride the bicycles with big loads on the back.
There's no telling how far this guy hauled his load. I took this picture on the Sake road, well outside of Goma. He probably walked at least 10 kilometers, maybe more.
