Lance Armstrong faced doping-related litigation charges in both the United States and United Kingdom and in one case, readers accused the athlete's inspirational books as being fraudulent. 

A class action lawsuit was brought against the former cyclist by two Sacramento men who purchased and read Armstrong's books "It's Not About the Bike: My Journey Back to Life" and "Every Second Counts," and who now claimed the book is a fraud, Sports World Report noted Monday.

Rob Stutzman and Jonathan Wheeler said in their lawsuit they "would not have purchased the books had they known the true facts concerning Armstrong's misconduct and his admitted involvement in a sports doping scandal."

In the class action suit, the men claimed they feel cheated after Armstrong admitted to Oprah Winfrey earlier in January to using performance enhancement drugs during his cycling career, in which he amassed seven Tour de France victories.

"Both books have now been exposed as frauds," the plaintiffs said.

The 57-page lawsuit stated quoted passages from Armstrong's book in which he denied doping, claiming his accomplishments as an athlete were achieved without the help of banned substances. 

"Plaintiffs and class members would not have purchased the books had they known the true facts concerning Armstrong's misconduct and his admitted involvement in a sports doping scandal that has to his recent and ignominious public exposure and fall from glory," the suit read.

Armstrong is also at the center of a lawsuit filed by his former teammate Floyd Landis in federal court in Washington. In the 2010 complaint, which has yet to be settled, Landis accused Armstrong of going against the sponsorship agreement his team had with the U.S. Postal Service by using banned substances to enhance her cycling performance and blood doping to win the Tour de France.

In the U.K., the Sunday Times is trying to get back $1.5 million from a libel lawsuit filed by Armstrong that it settled in 2006.
