@natebosshard @joshelman @rfradin If you want to argue that people who use Pelotons use them more than people who have gym memberships go to gyms, then retention attendance. If you want to argue overall size of biz, you do paid members/subs, and you look over time. Of course early Peloton members will overindex. — PolitiTweet.org
