Bike design: No simple matter

This technical demonstrator of HyperSizer Express frame geometry for an optimized hardtail mountain bike shows a layup of 0°/90°/±45° tape plies. The ply schedule is designed to meet typical requirements for performance bike frames, including ply-based strength criteria (Ref: Tsai-Hill, Tsai-Wu, Tsai-Hahn) as well as pedaling stiffness requirements (transverse bottom bracket deflection) for efficiency, and head tube stiffness requirements (transverse head tube deflection) for handling.
