In the September of 2020 Alex Lewis begins his quest to become the first quadruple amputee to complete the 12-day circumnavigation of the Gobi Desert. To do this he tasked a team of fourth-year engineering students to design and build a bespoke, electrically assisted hand-cycle. In order to effectively, quickly and safe complete the task the following systems were designed and built: A strong light-weight aluminium chassis; an electric assist system capable of reaching speeds up to 30 km/h; a combined cranking, steering and braking mechanism; an intelligent solar panel system capable of actively charging two batteries; an automatic gear shifting system. Through the integration of these systems the team believe they are creating a world first product.
