The extra large deck can be used to store all sorts of cargo. Otherwise Chukudus can be used like any regular kick scooter, or like knee scooters given their higher decks.
According to locals, they appeared in the 1970s during the dictatorial reign of Mobutu Sese Seko, back when the country was called Zaire.
One Chukudu builder says he uses fire treated Eucalyptus wood for extra strength. The Chukudus can hold hundreds of kilograms. Parts like springs and bearings are salvaged from old cars and trucks. His handmade scooters are available for $50 to $100 dollars, though many are available for around $20.
For extra large loads, the Chukudus can be used like push carts.
