I am selling our Stamina X Air Bike. We bought this in December of 2023 to help the wife get moving while at home. However, she shortly there after started to develop back problems making the biking difficult. She ended up needing major back surgery and cannot sit comfortably on this equipment anymore. Walking is better for her situation. So, I hope you can add this to your home gym because it is a great bike. It is heavy and solid and fun to use. You can visit the Stamina Products website and read all about this item. If you have any questions feel free. I use a cross country skier and have for years, in case you were wondering why the old man doesn't keep it for himself.
