“Bikers” is the fan title for an unreleased A. G. Cook song, premiered live at Pop Cube in 2015. The track’s actual name and future are unknown.

The song was confirmed to be Cook’s in a fan interview with SOPHIE on Medium.com:

F: “Flowers and petals, higher and higher and higher” — what’s the deal with this song? Is that one of yours? Does it have a name?

SOPHIE: This was made as a birthday song for me by AG Cook. It’s about one day when we first went on a car journey together and some bikers got angry with us… It’s so good, right? QT loves it so we listen to it together sometimes.
