We use the bikes for interval conditioning. They're getting cold now that we can push the Prowler and have the C2 rower. Don't have the make/model in front of me. They're from the early $hoe$string days of Greysteel--the absolute cheapest goddam thing we could find. (I started Greysteel with less than $5k for my budget.) They're not great, merely serviceable. I may junk one of them to make room for something else soon.
