Ask any Peloton user what they like about their bike, and most answers would probably include some reference to a Peloton instructor rather than the bike itself. It's been written many times before, but it's worth noting again: Peloton's big draw is a combination of the instructor personalities, pick-me-up mantras, and music playlists. As the company wades through the hardware muck and a massive corporate restructure, its special sauce--and source of recurring revenue--is still its software platform. So it makes sense that Peloton's first big new feature in a long while is a software feature. What's more interesting is that it involves no instructors at all.
