SoulCycle's co-founders are leaving their positions at the brand. 

Elizabeth Cutler and Julie Rice "have resigned as co-chief creative officers to 'pursue new projects,'" Fortune reported. The co-founders will stay on the company's board. 

The pair founded SoulCycle a decade ago with one studio on the Upper West Side. The brand filed to go public in July, but gym brand Equinox currently owns a 97% stake. 

The brand is planning an expansion into new studios and at-home cycling workouts. 

With each class costing $34 and no unlimited membership option, SoulCycle can get pricey. 

SoulCycle's third founder Ruth Zukerman, left the brand and started a major competitor called Flywheel.

Many cycling studios are vying to capture people who are interested in indoor cycling, but SoulCycle is still the undisputed leader.

"There is really something about putting people in the dark, letting their endorphins flow, playing loud music--we call it the perfect storm," Rice told The New York Times.
