We need better tools and design processes to develop on-bicycle user interfaces, for example, for hazard warnings, and to overcome design challenges associated with the cycling context. We present a physical computing toolkit that supports the rapid exploration and co-design of on-bicycle interfaces. Physical plug-and-play interaction modules controlled by an orchestration interface allow participants to explore different tangible and ambient interaction approaches on a budget cycling simulator. The toolkit was assessed by analysing video recordings of two group design workshops (N=8) and twelve individual design sessions (N=12). Our results show that the toolkit enabled flexible transitions between ideation and out-of-the-box thinking, prototyping, and immediate evaluation. We offer insights on how to design physical computing toolkits that offer low-cost, `good enough' simulation while allowing for free and safe exploration of on-bicycle user interfaces.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Informatik, INF 5 - Institut für Anwendungssicherheit, Professur: Alt, Florian}, }
