The Dan Bilzerian bike bet has gotten a little more interesting in the past few days after heavyweight biking champion of the world Lance Armstrong, and the most successful female poker player in history, Vanessa Selbst, both got involved via Twitter.

Dan Bilzerian’s Instagram account is laden with photos of blonde and brunette bikes, but this week a few of them have been shunted aside for a few metals ones.

What’s going on you may ask?

Last week, Bilzerian offered Samantha Abernathy $10,000 if she could ride a bike from Las Vegas to Los Angeles in 72hrs without dying. Bill Perkins picked up on that challenge and created one of his own when he challenged Bilzerian to do the same but in 48hrs.
