Some thoughts on your comments Not apples with apples Maybe try them both first I don't know anyone who uses different bikes on their trainer unless one is in for repairs. Can't see any use or benefit in swapping bikes out. TO ME it's a huge benfit to have 1) a quiet trainer and 2) not waste your tire away. So no need for an extra training wheel, cassette and tire which only add cost and get in the way when not in use. Factor those in and you're a lot closer to the KICKR's asking price. Don't know of any power meter that measures power on the tire or outside of the wheel. The KICKR's flywheel compensates for the rotating mass effect. I used other power meters on the trainer and as the review says I found the KICKR to be accurate and, more importantly (to me), consistent. Unless you're training for bragging rights I feel it's more important to have a baseline to work from and improve from there. Wasn't an issue on any of the devices used. No more than usual using my phone as my training GPS using Endomondo or Today's Plan. Just lock your phone's screen when using the RFLKT+.
