Robert ("Bob") Charles Mionske (born August 26, 1962) is a two-time U.S. Olympic racing cyclist (1988 and 1992)[1] and U.S. National Champion (1990).

In the 1988 Summer Olympics, held in Seoul, South Korea, he placed fourth in the Individual Road Race.

He retired from professional cycling in 1993 and is now an attorney based in Portland, Oregon, with a practice in bicycle law.

Mionske subsequently spent countless hours in the saddle of his touring bike, exploring the forests and lakes of Wisconsin.

After graduating from Wilmot high school, Mionske enrolled at the University of Wisconsin–Madison, where he continued to ride a bike—an old cruiser—for transportation around campus.

Mionske reports that one day in his Latin class at the university, he noticed that one of his classmates had the shaved legs typical of a bicycle racer.

In 1988, he tried out for the U.S. Olympic cycling team; his third-place finish in the road racing trials garnered Mionske a spot on the U.S.

[10] Racing for the United States in the 1988 Summer Olympics in Seoul, Korea, Mionske came in a close 4th, achieving the same time as the 3rd-place winner, but losing the bronze medal by a tire's length.

[21] In 2001, Mionske authored the legal analysis section in Bicycle Accident Reconstruction for the Forensic Engineer.

[28] Mionske's 2007 book Bicycling & the Law is a primer on all facets of U.S. bicycle law as it pertains to the average cyclist, and the first book on the topic written for the average cyclist since The Road Rights and Liabilities of Wheelmen, published in 1895.

In "Bicycling & the Law," Mionske advanced the argument that cyclists have a legal right to travel (that is, bicycling is protected under Freedom of Movement jurisprudence, in contrast to licensed forms of transportation, such as driving, which are not by right, but by permission only), a theme he first explored in his "Legally Speaking" column.
