So. Much. Testosterone.

A group of custom bike builders engage in a giant "pissing contest" (not my words) in this exclusive clip from History's new reality series "Battleground Bikers Phoenix," which follows "the temperamental and talented bad boys of the bike business" in the city as they "compete day and night" to gain an edge over their competitors. Which sounds stressful, but okay, good for them.

In the clip embedded above, the big manly biker dudes challenge each other to a - surprise! - bike-building competition at Arizona's Hideaway Grill, which in no time at all escalates to schoolyard-level name-calling and shameless acts of emasculation.

"Battleground Bikers Phoenix" premieres Tuesday, July 1 at 10 PM on History.
