With the rise in popularity of bike-sharing has come the rise in misuse of the term. I see bike-sharing as bike transit which is available at unattended stations to the general public, usually in urban locations to complement the existing transit network. This is different from bike rental which is for recreational purposes and private-use programs, like those of universities, residences, and employment sites, which are used school, work, and recreational trips, respectively. Each are perfect for their own intended uses. There is also a gray area between a few of the branches.
So here I present the "Phylogenetic Tree of Bicycle Use Programs" or more simply "Bike Use Programs Family Tree". The tree is divided into types of programs, providers of these programs, and known examples of each with their level of sophistication defined by their generation.
My goal with producing the Tree is to put governments, universities, residences, and organizations on the same page so we're using the same terminology. This can only be beneficial to the concept of bike-sharing.
What are your thoughts? As this is a work in progress, do you have suggestions for clarification or improvement? Let me know.
