The durian (IPA: [d̪uˈɾi.ɑn]) is the fruit of trees of the genus Durio belonging to the Malvaceae, a large family which includes hibiscus, okra, cotton, mallows and linden trees. Widely known and revered in Southeast Asia as the "King of Fruits,"the fruit is distinctive for its large size, unique odour, and a formidable thorn-covered husk. Its name comes from the Malay word duri (thorn) together with Malay suffix that is -an (for building a noun in Malay), meaning "thorny fruit."Actual, there is no 'direct' relation between Durian and Cycling but in case that you are riding your bike and accidentally found durians at the side of the road, tie the durians on the top and both sides of the rear rack with a bungee cord that will press them securely to the rack (see above picture- btw that is steve's leg)...and you are good to go!
