They could just buy Peloton. "Apple Peloton".
To put it another way: why should Apple buy Peloton? Apple itself is already a premium brand with huge awareness, so a buy for brand reasons isn't that persuasive. Peloton has a whole range of hardware but none of it is compatible with existing Apple hardware, so integration might be a drag.
Apple would want to design their stationary bike from The ground up w their bicycle experts. (They may already have done this a few times)
Also, letting Peloton do it’s thing is a small safety valve on the anti competitive question.
