Design of a front seat for the Buddy tandem tricycle through user empathizing. A conceptual design for a specific target user in a specific context of a new bicycle design.

This thesis investigates the design of a front seat for the "Buddy" tandem tricycle, focusing on key features that enhance comfort and confidence for elderly passengers (65+) with changing medical conditions. The research aims to identify the functionalities needed to effectively meet the needs of the target group and to understand why existing seat designs, such as those from HP Velotechnik or VanRaam, are not viable solutions currently. The subgoal is to create a prototype integrating these functionalities for further development by VanRaam. The design brief addresses the question: “What are the essential features for the front seat of the ‘Buddy’ tandem tricycle to maximize passenger comfort, confidence, and aesthetics?” Using the Design Thinking approach, this study involves iterative low-fidelity prototyping and user-centred design. Key findings indicate that a functional seating angle of 123 degrees, side bolsters, lumbar support and adaptable ergonomics are crucial for meeting the target group’s needs. The iterative process reveals that both ergonomic and perceived comfort and stability are critical. Furthermore, aesthetic design plays a vital role in perceived comfort and stability as well. While the study demonstrates the value of user-centred design, it also notes limitations due to the time-intensive nature of the iterative process. Future research should include materials, business case, bicycle access and durability tests.
