If successful, the results of this research will improve the fundamental understanding of how humans interact with bicycles and will help to pave the way to the design of bicycles for a wider population audience and for a wider range of tasks. Systematic design of bicycles with more utilitarian purposes (as opposed to recreation) may be made possible, which in turn will lead to lower cost, healthier, and more sustainable modes of personal transportation. Graduate students will be directly involved in the research as well as in the dissemination of the results through classroom instruction, scientific publication, and outreach activities at the K-12 level and local science centers. The familiarity of children with the bicycle makes it an ideal candidate to spark their interest in future engineering careers.
