EV360: Electric Monowheel

Our team has designed and built a one-wheeled electric motorcycle designed to be capable of reaching speeds in excess of 70 mph.  

We're not an official Duke team or organization; we're a group of friends who don't have a garage, established funding sources, or dedicated tools like most motorsports teams. We've built this vehicle just about from the ground up. 

Introduction

During the summer of 2018, I was hanging out with a friend helping him clean up one in one of his labs; on his computer, I saw a window pulled up with a picture of a monowheel. “What’s that?” I asked. After explaining that he had been looking at cool science-fiction style vehicles out of curiosity, I said “let’s build one.” That’s how EV360 was born.

Our Team

Our team consists of Fran Romano, documentarian, Kristine Stanners, Event Planning, Logistics, and Publicity, and four mechanical engineering students: Ahmed Ahmed-Fouad, Carlo Lindner, Jolán von Plutzner, Anuj Thakkar. The team was founded by Anuj Thakkar and Logan Fettes.

Recognition

APPLE: During the early design process, Apple featured the monowheel in a commercial based around the application of their technologies in an educational setting.

RUBENSTEIN ARTS CENTER: After a public display of the monowheel at the Rubenstein Arts Center (Ruby), the Ruby featured the monowheel on the cover of future printed content. 

INNOVATION CO-LAB: After the vehicle’s first public display, Duke University’s Innovation Co-Lab made the vehicle the centerpiece for visitors touring the facility.
