I have a Kickr Gen 1 with a VeloBike adapter on there. It works ok for starts.
I had to use chain tensioners to set it up and it holds ok with the QR system. The Kickr resistance curve is odd. I've used it in standard mode and adjusting levels and percent resistance. I've struggled to find the sweet spot where the initial load is sufficiently challenging but that does not allow me to get the freewheel spinning to quickly.
