The Olympian posed with the book in front of a giant gold medal and images of her competing for Team GB in the velodrome.
Pendleton later signed copies of Between the Lines for fans.
The autobiography documents the 32-year-old's "considerable lows, as well as the well-known highs" and reveals "in searingly honest detail" how cycling "was starting to tear her apart".
Pendleton is currently competing in Strictly Come Dancing alongside fellow London 2012 athlete Louis Smith.
She will return to the ballroom with professional partner Brendan Cole for the BBC contest's first performance show on Friday, October 5.
