Performance duo Kailey and Kelianne recently uploaded a video of this dance routine to Justin Bieber's "Sorry" that takes place on hoverboards, or mini Segways, or whatever you want to call them.

The routine starts out with some difficult gymnastic-inspired moves.
Then it progresses to gravity-defying group moves.
Starting at around the 1:40 mark, the women bring the house down with a cumulation of choreography and athletic ability.
They definitely give the dancers in the official video a run for their money.
Bieber better take note.
BuzzFeed has reached out to Kailey and Kelianne for comment.
