Design Interventions Towards Optimization of Drive Features in Electric Bicycle in Adherence to ISO 4210

The bicycle promises to become an important mobility device that promotes green solution to pollution menace in domestic short distance travel. Its structural design involves the frame as the vital part that gets subjected to severe fatigue loading that has led to accidents and expensive product recalls. The frame is the key load bearing member that decides user safety, demanding a stringent design, appropriate weld process and base material adoption. This study develops baseline model using BikeCAD Open-Source tool for component selection and design. The material selection coupled to fatigue test based on ISO 4210 helps to simulate failures and behavior of weld affected heat-zone. The iterative method checks various gauge of steel to identify safe thickness for bottom tube. In the final stage, results of standard frame were subjected to suitable design interventions leading to modified version that are safe with additional features of enhanced range and durability.
