Cyclists desperately try to keep their heavily-laden bicycles upright as they arrive at a market with baskets full of pineapples on August 23, 2018. The men travel up to 12 and a half miles with two baskets tied to the sides of their bikes, carrying between 50 and 100 pineapples to sell. Each of the bicycles is so heavily laden with fruit it is impossible for the men to actually ride their bikes, instead having to walk alongside them.
