The aim of this project was to explore what was possible to maximize rider comfort for cycling saddles. Since saddles are a main point of interface between rider and cycle, comfort is paramount to the experience of the rider. Currently, there are designs that mix different geometry and materials to specifically match a rider's needs for one situation. However, the situation changes when they are riding road versus trail or even long vs short riding. A saddle needs to be versatile throughout a season. The Engine system is a proposed solution that brings versatility and personalization.
