For the final project of the class on computer-aided mechanical design, we were tasked with building simple two-wheeled vehicles that could be pedaled by the rider. Our di-wheel went a little above and beyond, as it was the only one that had a fiberglass seat, a working differential, and of course, a spoiler. I was principally in charge of frame design and construction. Another special feature of our vehicle was that it didn't have any frame members in front of the driver to obstruct their ingress or egress, which if you're in the middle of a relay race gains you all-important seconds. We were able to make the frame rigid enough with ribs and braces so as to not necessitate a front member.
