Sounds like your wife had an Airdyne. I really really wish I could find an Airdyne bike for $99, they're fantastic. I bet someone will pay you for it even broken. Strength and conditioning coaches love them. Unfortunately, you're not going to find anything nearly as good as your Airdyne unless you find a used Airdyne.
You can get yourself a cheap trainer in a lot of sporting goods stores. I have one I paid sub $100 for, I use it 4-6 days a week for the last 2-3 years doing both HIIT and LISS, and it's still working fine. It's a Schwinn brand that I got from Canadian Tire.
