Im shocked at the retail value of this...its saying 849 but on sale for 449....I think i got it on sale on amazon for like 150$ a couple years ago. It really does nothing special at all, you can change the resistance between 0-99. It works fine, the seat really isn't comfortable at all but its a bike not a couch. I would not recommend for the price its listed for but if you can get it cheaper I don't have many complaints.
