This mid-term presentation by Jon Gutierrez, Chris Sauer, Simon Radomski, Chat Huynh, Jeff Burton, and Robert Platt outlines the development of a bike designed for cliff-jumping. The project aims to analyze mechanical advantages of different suspension systems, evaluate rider impact during jumps, and optimize bike geometry for enhanced performance and safety. Key focus areas include the characteristics of hard and soft suspension, traction analysis, and the generation of forces affecting the rider. This involved design partitions and numerical evaluations to ensure the bike meets desired capabilities.
