Similar to flight or car simulators, bicycling simulators are an ideal tool for low-risk research, training and communicating visions of the future.
However, one point of criticism of bicycling simulators is their validity, as there are still major technical challenges in realistically reproducing the bicycling dynamics of a single-lane bicycle (so-called physical validity). On the other hand, in every simulator study it must be questioned whether people behave in the same way in a virtual reality as they do in the real world (so-called behavioural validity).
The aim of this work is to create a systematic overview of methods already used to determine validity in order to provide practical assistance for researchers dealing with the validation of bicycling simulators and at the same time to contribute to the comparability of the methods.
A data set from an existing systematic literature research is provided as a basis, which is to be further analysed in this work. In addition, a literature review on the validation of simulators in general will be carried out in order to develop the methodology for the evaluation and basis for the subsequent discussion of the results.
The result of the work will be transformed into a practical aid for simulator researchers as part of the OpenBikeSim project and made available as open-source knowledge on the project website, so that a great practical benefit will result from this work.

• Which methods for assessing the physical and behavioural validity of bicycling simulators have been used in previous studies?
• Which conclusions about the validity of bicycling simulators can be derived from previous validation studies and which research gaps still exist?
