Some customers of Equinox and SoulCycle, which are known for a clientele that is largely urban and female, criticized the fundraiser on social media, threatening to cancel their memberships.

I am a freak who loves @soulcycle. it genuinely makes me feel good and excited about my body and my health. that being said, the loser owner supports trump and I didn’t know that! so I will no longer take classes there. sharing bc I had no idea & maybe u didn’t either! fuck that. — Mitra Jouhari (@tweetrajouhari) August 7, 2019

The indoor cycling chain's CEO Melanie Whelan said in a statement later Wednesday that Soul Cycle "in no way endorses the political fundraising event."

"Soul cycle has nothing to do with the event and does not support it," Whelan said in a statement. "Consistent with our policies, no company profits are used to fund politicians."
