This is a tough question to answer, because it depends on what kind of cyclist you are. If you're new to cycling and want the gym experience at home, the biggest competition to Peloton would be the Myx II Pro referenced above. If you're a more advanced cyclist looking for a way to get in a variety of workouts at home without needing to go to a scheduled spin class, the competition to Peloton would likely look more like an indoor trainer where you're using your own road bike hooked up to a Wahoo Kickr Smart Trainer. Because indoor bikes like Peloton reach such a broad audience of cyclists, your personal level of enthusiasm has a ton of weight on your choice.
