Fortunately, I was not encombered (sp?) with a college degree. I barely made it out of high school as my poor spelling in these posts will attest. Most people are educated far beyond their need or capacity. I chose to start a business at 17. Retired at 38 with no need to ever work again. I did OK. As for the need for a "academic paper" on bikes? Seems a little trivial if you ask me. And I ride the things (bikes) all the time. You can over think simple subjects. So I maintain any school that would accept such a work as a serious effort is not worth a damn. Might explain the dearth of research materials the poster is seeking.
