Bike model Validation

Hi,
I have a questions concering the bike 2D and bike 3D model. Are both validated? Have they good results when they are compared with the literature?

Thanks, best regards
Manuel

Hi Manuel,

You are asking a good and difficult question. I could answer yes, because some people have indeed validated the models against experimental data and have obtained good results. I could also answer no, because they did not validate the models in all possible cases, and I remember at least one case where a couple of users tried to simulate the case of biking with a vary large lateral distance between the pedals and did not get good results.

It goes to the core of the question: What is validation? Is a model and software validated when it has been proved to work well in every conceivable situation or when it has been shown to work well in a single or a few situations?

I can confirm that we and a Dutch group independently obtained good results with both the 2D (many years ago) and the 3D model.

Best regards,
John
