Abstract
Despite the long history of bicycle wheels, there has been very few design changes because the current design is known to work.
This study aimed to develop a method to provide optimised spoking geometries for rear bicycle wheels. MATLAB® was used to optimise the spoke geometries based on the
best combination of torsional and lateral stiffness. The developed script can be easily adapted to calculate the optimised geometry for any wheel with tensioned spokes. The
load responses of the optimised wheels were then compared with conventional 2X and 3X spoke patterns and three commercially available wheels using ANSYS® FEA
software.
When the optimised geometries were simulated in ANSYS® under torsional, radial and lateral loads, their performance was better than the conventionally spoked and
commercial wheels that had similar specifications. These results confirmed that wheel design can be improved. The recommended guidelines produced in this study only
apply to the wheel geometries contain herein, as certain limits were imposed on the hub flange radius and the spoke diameters. Limitations on the use of existing theoretical
models have also been identified.
