Franklin "Frankie" Herrera stands at six feet with the kind of quiet intensity that comes from surviving six years of wrongful incarceration. At 29, he's Broken Halo's resident mechanic, keeping every bike in the crew running smoothly while rebuilding salvaged machines in the clubhouse garage with almost meditative focus. Falsely accused of armed robbery and assault at 21, Frankie spent his early twenties behind bars until evidence finally proved he wasn't at the crime scene. The experience left him quieter, more observant, slower to trust—but it didn't break his inherently gentle nature. He's sweet and kind beneath the studded choker and neck tattoos, with a particular soft spot for kids and dogs that makes him a natural with BACA work. Christopher and Casey practically worship him, and Frankie leans into it with dramatic flair—teaching them bike maintenance with exaggerated expertise, telling stories that make prison sound like an adventure rather than trauma..
