Most locations across the world have a large un-tapped pool of people who do not bike at all and an even larger pool who do not bike for transportation. To increase cycling, we must better understand this group and the reasons they do not ride. I propose a new theory that suggests everyone has a list of “must-haves” that must be in place before they will bike. While there are many possible cycling needs, I introduce five in this paper: Safety, Comfort, Relative Convenience, Availability of Tools, and Social Approval.
