Since you are asking in the bike discussions I'm assuming you are talking specifically about the bike.
1) If you want to purchase the bike outright it's $2,245 to $2,694 plus tax. The range depends on which accessory package
you want accessories for things like shoes, mat, HR monitor, etc. with it. That includes delivery, setup and one year warranty. Then there is an ongoing subscription fee of $39/month. This includes access to thousands of classes - cycling as well as boot camp, running, Yoga, meditation. You can also share this with others in your household. There is a mobile app which works well for things other than the bike and while traveling, etc.
2) If you want to finance, they have an option for $0 down and you pay the subscription fee plus pay off the bike over time each month. That can be as little as $58/month they say depending on the package and length of loan. I'm not normally an advocate of financing anything but if the bike will take the place of a gym membership or spin passes that cost more than that I think it could make sense.
3) The least expensive option is to just try out the app which costs $13/month and buy an inexpensive spin bike. Probably something off of Craigslist would be your best bet. You can mount an ipad on the handlebars and have a similar sized screen. If you really like it and want the benefits of the metrics you can then decide to make the financial commitment to the actual bike. This was how it happened for me - I only lasted about 4 weeks before I decided I wanted the bike
One note - if you subscribe to the app now only one person can use it. This changed as they used to allow something like 8 profiles per account so it's more difficult to share with family members. The app has a 30 day free trial right now.
Also, if you buy the bike, make sure to use a referral code. Anyone who has a bike or tread can give you one and it will get you $100 off of accessories when you purchase. They will also get $100 credit at the boutique. If you don't know anyone let me know and I'll send you mine.
