The purpose of this study is to provide the necessary technical background and data for the development of a suspension system for a recumbent bicycle. For this reason, the customer requirements-design criteria for the development of the suspension system were set, and several static and dynamic tests were conducted on the bicycle's suspension components in order to determine their shock absorption properties. The shock absorption properties of the bicycle's components can be used as means of evaluating the specifications of the suspension system that will satisfy the established design criteria best. In addition, a test machine that can be used for damping coefficient and spring constant measurements was designed to provide further assistance with the analysis of the damping and elastic properties of the recumbent bicycle's suspension components. It was designed so that it can also be used for similar testing of other materials and parts used in the bicycle industry. The subject of this study was BikeE, a recumbent bicycle that was developed by Professor D. G. Ullman and the BikeE Corporation in 1992. / Graduation date: 1995
