It seems like Airdyne, Rogue Echo, and the Assualt air bike are the big three. And between them, there are different models.
Is one notably better than another? Is one model the way to go? I have a Concept 2 rower, this would be used in addition. I like to buy “best value” or “best all-around” over cheapest or most tricked out, generally speaking. That sweet spot. Is there one with these?
