This paper investigates the transferability of measured loads for the semi-analytical multibody simulation of bicycles, addressing a significant challenge in accurately determining realistic operating loads for bicycle design. Traditional testing methods often fail to replicate the complex and variable conditions encountered in real-world scenarios. A solution is a semi-analytical simulation approach that utilizes measured load data at connection points between the bicycle and its environment, allowing for precise simulations without detailed models of human interaction or tire dynamics. This study evaluates how well measurement loads can be applied to different bicycle geometries by analyzing variations in critical dimensions such as head tube angle, chainstay length and reach. The findings aim to establish relationships that enable the prediction of changes in system loads when transferring measurement data across similar bicycle structures, potentially reducing the time and costs associated with prototype testing.
