A smart trainer (wahoo, tacz etc) connected to Zwift, Trainerroad, Sufferfest, Rouvy, Bkool or similar. There are loads! I use Zwift and Trainerroad. However, I don't think these actually compete with Peloton. Peloton is like going to a gym class. You just follow allong, and show up when you want to and go mostly all out. It's a nice workout, but often not aligned with long term goals. But TR for instance one gets a tailored plan based on one's race goals that season.
