The Hauler, from Senkai Motor Works in Hood River, Oregon is an electric-assisted "human utility vehicle." Powered by solar, sweat, and electricity, the Hauler is designed to bridge the gap between bicycle and car. The end goal is to bring affordable utility and mobility to millions in China and the US.
A solar panel that doubles as a roof over the cargo bin is a feature designed to extend the range of the motor. It can deliver a full charge to the electric battery over the course of a day.
