The Nordic Track S22i is one of the more unique style spin bikes currently on the market. As this unit works off a magnetic resistance the unit is quiet as it adjusts the resistance levels for you automatically. You can override this functionality as well and control the unit independently. One thing of note is as the unit does incline and decline there will be noise from the back motor as this occurs, similar to that of a treadmill as it inclines up.
Nordic Track supplies one year of their iFit subscription along with the purchase of any new unit. This is a great startup for people looking to access their vast on demand class or scenic rides. These on demand classes/rides allow the instructors to control the bike for you so you can focus on your workout. At this time however they do not currently have any live on demand classes. For those looking to have a lot of content through the years this is a solid choice in general. Make sure before purchase your wifi signal is strong enough so you do not have any buffering issues, a little is normal at the beginning of each workout.
Overall this is a great choice for those looking to stay entertained while working out, while also removing the static same routine workouts.
