Nichols.

Nichols is an American Western television series starring James Garner broadcast in the United States on NBC during the 1971-72 season. Set the fictional town of Nichols, Arizona, in 1914, Nichols differed from traditional Western series of the era. The main character, a sheriff, rode on a motorcycle and in an automobile rather than on the traditional horse. The hero did not carry a firearm and was generally opposed to the use of violence to solve problems, preferring other means. Margot Kidder portrayed Ruth, the love interest/barmaid of Nichols.
