Human powered vehicles can play a role in overall urban transport solutions. This is an open access article under the CC BY-NC-ND licenseįinding solutions for efficient modes of urban transportation is becoming more pressing given concerns over fossil fuel depletion and climate change. In addition, eDrive can be configured and scaled to provide CVT functionality for a variety of other vehicles and machines, such as wind or water turbines and electric vehicles. The eDrive promises to increase a bicyclist's user experience, provide more efficient conversion of human energy to locomotion, and overall promote sustainable urban transportation. The sprocket accommodates a rotational input and provides an output using a loop belt rotationally engaged with sprocket. The eDrive incorporates a sprocket able to vary its effective diameter via computer controlled actuation. These attributes allow eDrive to be used in human-powered transport devices such as bicycles. Unlike many CVTs that are relatively heavy and bulky, the present CVT, named "eDrive", is fairly small and lightweight. This paper describes a new continuously variable transmission (CVT) that may be used in a variety of machines and transport devices.
