This document summarizes Neil du Preez's proposal for Mellowcabs, an electric three-wheeled vehicle designed for urban passenger and cargo transport. It notes that 80% of urban trips are short and emissions from urban transport are high. Mellowcabs aims to provide a low-cost, efficient, and emissions-free solution. Prototypes have been developed and road tested. Partnerships have been secured with Uber and logistics companies for pilots in multiple countries. The proposal outlines the market opportunity and competitive advantages of Mellowcabs.
