I'm surprised no one has compared Peloton. And, also surprised that Peloton can get away with charging ~$50/mo. But, then again, that's not so far off. I see activity on the Peloton tapering off a bit after the first few months of usage, and that in person colleague effect seems powerful. It isn't the same when you are seeing random people on the leaderboards.
Just got into Zwift, after getting a Wahoo Kickr for my road bike. This service is 100% amazing, highly addictive - and very affordable. Haven't even done a race yet, structured ERG mode workouts and hill climbs are so darned enjoyable. Have my squat rack metres away; home gyms are amazing.
And with the weekly emails and monthly events, they seem to actually want you to use the service, unlike the stereotypical gym model. Maybe because an Apple subscription is so much easier to cancel?
