The mount includes a first mount member or portion secured to a bike such as in an end of a tube of the bike frame or a tube attachable to the bike and left in place after attachment. A second mount member or portion of each accessory is interconnectable with the first mount member. A lock member preferably utilizing spring ball detents on a lock pin shaft is utilized to releasably interlock the first and second mount members together to prevent unwanted separation.
