MotoVai is a simple wooden cart that attaches to the back of a motorcycle. It is designed for use by small middlemen in Brazil who transport mud crabs from mangrove to market. These middleman are currently limited to selling the small number of crabs they can carry on the back of their bikes, which is usually limited around 140-200 crabs. But the MotoVai will enable them to quadruple this number, significantly increasing their earning potential. This product will be marketed and sold through a local entrepreneur with support of the conservation organization, Rare.
