Keiser M3i Wheel Circumference for TR App

Apologies if this has been covered - I did a search and didn’t find anything, specific to the M3i, and I’m afraid I couldn’t really understand any of the more general posts on wheel circumference calculations.

The Keiser M3i has a 16" wheel circumference. I’m wondering what the applicable entry into the App should be? Thanks for the feedback.

No, you really don’t want to use the actual size from the trainer bike. Generally speaking, it’s best to use something like the typical 700 x 23c or 25c tire size, that is 2096mm or 2105mm respectively.
