I will be watching this with interest. We do have one of these bikes, and my wife has put in 150 rides over the past 6 months. It’s an extremely well built bike, the classes are for all levels, and the motivation of live classes and a team spirit brings the gym feeling home. Of course without the driving back and forth which is a huge time saver.
The high pricetag is definitely a barrier to entry, but as others have said over time if one goes to the gym only for spin class it will even out.
They have recently come into problems with music licensing, which while not a huge deal is a potential red flag that they may have missed some due diligence along the way in other things.
