Biles debuted her vault, a "roundoff, back handspring with half turn entry; front stretched somersault with 2 twists" (an upgrade from the Cheng) at the selection camp for the 2018 World Championships. During qualifications at the 2018 World Championships Biles successfully landed the new vault and it was therefore named after her and assigned a difficulty value of 6.4, tying it as the most difficult vault in Women's Artistic Gymnastics with the Produnova. As of , Biles is the only woman who has performed the "Biles" vault.
