What is Open Source Bicycle Design?

I don't understand your question. Can you reword it?

I'd argue there is a stagnant design industry around bicycles. The major manufacturers are greatly restricted by the market as well as international racing regulations, on their ability to innovate. Meanwhile most small custom builders don't have the R&D luxuries.

Open source bike design can lead to rapid iterations for improving human powered transportation.

Starting with a new methodology can yield un-predictable results. This is a good thing in terms of innovation.

For a good example of open source bicycle design look up Python recumbents. http://www.python-lowracer.de/
