I purchased a Saris MTR rack for my RadCity ST with fenders because it could securely hold the bike touching the tires and not the frame
I have the same rack, and like it pretty well. On an April trip over Snoqualmie Pass to eastern Washington, it carried our 2 bikes with no problem. (One is an ebike--60+ lbs, the other an analog townie; both are step-thrus). Of course we had to use top tube adapters. What impressed me was as I watched the bikes in the rear view mirror, I saw no bouncing or wobbling back and forth, even on rough roads. Were it not for our fenders, I might prefer the type that grips the wheels, but don't want to give up the fenders. This was on the back of a Rialta (small motorhome).this one has worked well for my bikes. I have a 2.5" tire one for my kid and mine is a 4" fat tire. both fit and both have fenters.
