Our team sought to improve upon previous designs to achieve a lighter, stiffer wheel that minimized issues with impact steering, rolling resistance, and lack of stiffness in previous versions.
Starting with half-scale prototypes, we developed a form to minimize weight and maximize lateral stiffness (A notorious weakness of bicycle wheels). The design path was chosen from a variety of concept models considered by the team. The final design was reached through iterative prototyping.
Each 28" wheel weighs in at about 7lb (with tread), and supports over 200lb directly lateral to the hub, and far more axially.
