Hello, I am costing an electric motorcycle project (scratch built frame) to be engineered and registered in NSW. What does engineer and registration cost? What information do I need to provide to the engineer for him to approve the design? What are the minimum design requirements, frame strength, suspension, steering, components etc? Do I only need to satisfy the relevant ADR for motorcycle or is there a secret list of requirements? If this is not the right place does anyone know where I can find this information free of charge? What else do I need to know?
