It is also a disadvantage. The peloton bike is heavier (IE sturdier), has more grip options, takes up less floor space (the peloton is about a foot shorter than my actual bike, not including any potential trainer that would be required), is much more easily adjustable (if multiple people are using it), and is purpose built for the function it serves. I only have experience with one type of trainer, so this may be trainer dependent, but the peloton is also much quieter than the type of trainer I've previously used. Not to mention that when I want to go out and ride I don't need to detach my bike from the trainer, or when I want to get a workout I don't need to attach my bike to the trainer. As somebody that is primarily a bike commuter, the accessibility alone is worth having 2 bikes. And if you are going to have 2 bikes, why not buy an indoor bike that is specialized for the task.
