This article from Core77 shows how the development process of a concept can be aided with concept models. Note all the photos of “users” on the bike are staged in order to give the “impression” of how it would function. None of the materials used in the modelling would actually be used in the final product.
Professor Kevin Shankwiler of GeorgiaTech has been teaching a third-year bicycle design studio for the past four years. The 8-week course is primarily focused on understanding product systems design and exploring opportunities for innovation in commuter bike design. David Hotard was among the 12 students in the SRAM-sponsored fall studio, which culminated with four teams (of three students each) developing very different bikes. He worked with Matthew Campbell and Edwin Collier on re-imagining the hubless wheel as a cargo space; here Hotard shares how they arrived at the final product.
