I hate to say it, but if you’re having minor issues like that with a kickrbike… literally nothing is going to be any better.
But no, underneath the Pro is just a V2 with new controllers, and the V2 was just a V1 with likely one board change internally to include dircon (V1 has an RJ45 port but it’s for Wahoo internally).
You are heavier and likely more powerful than I am though; but that won’t make anything better anywhere else. The Kickrbike is quite heavy duty; going to a 3M or any trainer with a regular bike is absolutely going to suffer the exact same issues, and certainly have a lot more.
Unfortunately I can’t say I’ve had the same experience though, I’ve used my kickrbike every day since purchase with zero downtime… so I realize I’m not the best response.
But again, if some complaints are things like creaks and groans… (again not something I experience with mine, but I did pack my kickrbike with grease in lots of places Wahoo didn’t)… no road bike setup is going to be any better here but significantly worse; as they do flex, and aren’t designed to deal with anywhere near as much sweat on them.
The modularity argument I get, still, just be aware of the weights of these trainers; the 3M is 52lbs… but at least it has a handle! (SERIOUSLY the worst thing I hate abou tthe 2T is the lack of a handle; it’s so awkward to move, and can absolutely destroy your fingers if you aren’t careful folding the legs up).
If you seriously want to go down the road of a traditional trainer setup, my real recommendation then still is the 3M or the Wahoo KickrMove.
The fore/aft motion is wonderful, which I find it more comfortable than my kickrbike on a KOM Rocker plate; though I do wish I could lock the motion on my 2T like the 3M can for when I want to do sprints for example.
And I do really like my Alpine that I’ve only gotten to use a handful of times. The steering is… mildly annoying and I don’t use it all the time, but the range of motion is bonkers compared to the Kickrbike.
My takeaway… if the Shift isn’t for you (it’s not for me without the tilt personally), I’d look closely at the 3M and an Alpine as an addition down the road; but don’t expect to move things around once you get to that point.
It’s a weird benefit to know the Tacx can also work in case of a power-outage or… literally complete off-grid as well, which is not something any other trainer can do on the market; along with road-feel. Most users disable it… personally I like it once in a while and just have it set to 50% or lower.
I think you will greatly miss the instantaneous shifting of the kickrbike though; I do.. and after countless issues with Zwift’s hardware, I took it all off and am back to a regular chain setup on my first bike which at least has di2; but going up and down fast rollers, I greatly miss the instant shifting.
Lots of things worth considering!
But no, I don’t think you’ll find anything built any more superior in any way shape or form.
Maybe the Wattbike Atom (Not sure what the QFactor is on that thing) or TacxBike but those don’t appear to be options either.
Whatever you do come up with though, curious to see where you end up!
Oh one other addition to note, the Tacx also does allow freedom of left/right movement… also something no other trainers really seem to do that well / at all.
But of course this comes at a cost, as it is harder on the internals, and I’ve had a few teammates have to replace the main bearing on theirs before, which is down-time.
Downside to this though means… you can’t really comfortably use a gravel bike that’s too flimsy.
