This study will develop an expandable chassis that will be designed to meet the transportation needs of smallholder farmers. Farmers living in rural areas generally rely on motorcycles as their primary source of mobility, yet the fixed capacity, weight limit, and physical dimensions of these vehicles restrict them from carrying much of what they need. The curved design and the built-in locking mechanisms of the innovative chassis allow the user the option to increase both the width and length of their carrier, making it possible for them to transport larger items and/or multiple smaller items at once. Additionally, the chassis has been designed to remain lightweight, durable, and easy to attach to standard motorcycles; therefore, it is affordable, convenient, and practical for the typical end user.The expandability of the chassis is accomplished through an integrated arrangement of sliding structural components, which allow the user to easily, quickly, and safely make adjustments while remaining structurally sound when subjected to dynamic and irregular loads. Extensive material selection, structural design, and stress analysis have been conducted to ensure satisfactory strength, durability, and performance. The multi-purpose design of the chassis is intended to provide smallholder farmers with efficient and cost-effective options for transporting agricultural products, fertilizers, tools, and other equipment without incurring the expense of owning or leasing a large transport vehicle. By improving transportation efficiency, the proposed system will also decrease the need for manual labor, reduce dependency upon third party logistics and create cost-efficient rural transportation solutions. With its low cost of manufacture, straight forward operation and compact design, this system is well suited for the needs of small-scale farmers who require a flexible and multiply-adaptable method of carrying loads. Ultimately the research presented here has the potential to enhance productivity and support sustainable rural transportation methods through a scalable and flexible chassis design.
