Just getting back on my KICKR as our MTB season winds down. It is my 3rd replacement unit and was been good through the final few winter months.
Wahoo warranty and support has been top notch and quick for me. And I still love the unit.
Any idea if there is any pre-season maintenance I should do?

Hey guys! just dropped by to see if anyone has had issues with the 2017 Kickr.
I’ve had it for about 18 months now, and for the last couple of months when ever i’m coasting I started noticing the chain was being pushed (freewheel wasn’t working properly). I did some cleaning and re-greasing and ignored the fact that the problem persisted.
Last week I decided to actually look into it, and saw GPLama and others had had the sticky freewheel problem which was resolved by changing a worn out bushing, so I decided to write to support to get some help.
To my surprise, everything is fine in my trainer (no excessive wear, bushings and freehub are perfect), but this girl in support is telling me I need to buy a completely new “dented Flywheel” for US 100 + 70 shipping (I live in Colombia).
Just for reference the dented flywheel is the wheel in the top (the one with the white Wahoo logo). Since this is a casted part which carries the bearings and the dented ring (144T) where the freehub pawls couple when pedaling, I decided to take a closer look. I found that the dented ring is completely off-center due to a poorly casted casing! there is at least 1mm difference form each side and it is aggravated on movement. In the end, they aren’t willing to help out in any way since the trainer is out of warranty, but this is obviously something caused by poor manufacturing and not by normal wear. No “good will” practices by what I see… With that said, this is the first and last Wahoo product I’ll ever buy!!
Anyone has had similar issues??
This was on an original 2014 Kickr with… 10,000km(?) on it, iirc.
Ha! didn’t expect you would reply! Thanks for the clarification, I didn’t recall which model it was you had had the issue with! My Kickr has less than 2000kms on it.
I’m running on Third Kickr 2018. I got that unit on February 2019 and after that not a single problems. Have put approx 150h to that unit and I’m happy with the unit. I would like to think that the problems are pointed out and fixed by now. But cannot be really sure to be honest.
Wahoo support has been fantastic in my support cases.
Today my 1 year old Kickr Core is starting to make noises 
Yesterday it worked perfectly.
Do you think it’s easy fixable bei opening and tightening it all up?
Especially true if you are on the bubble for 1 year warranty (US at least).
i already made a support ticket.
Sadly i search for the invoce and it is 13 month old…
I hope i can fix it easy like her.
My replacement kickr (2018 model) started making loud scooter/Motorbike noises for about 4 weeks now. I changed bikes, oiled the chain, cassette, changed gears and could not figure out the problem. I finally contacted Wahoo. Turns out, this is a known issue. My second replacement will be arrive way soon. Hope my 3rd 2018 Kickr will do the trick.
i got an answer from wahoo.
My Core has to be replaced
So no Zwift atm…
Kickr Core here bought just a few days ago in the UK. Just read through a lot of this thread and it makes depressing reading.
First direct drive trainer so no comparison.
I’m getting vibration from the Core. Can feel it through the pedals, even the handle bar.
It’s only under load and NOT whilst coasting down interestingly. There is an associated droning noise too not massively loud and could be normal? Can’t tell if the noise is there during coasting as the freehub noise would downed it.
This isn’t a warranty unit. Its new off the shelf, November 2019.
Serial: 40192800***
@Finnbox no. Not normal. Open a ticket, and get ready to send it back. My .02? Cut slingload with Wahoo, and go with something else. I got tired of shipping Wahoo units back, that I got my money back and went the H2 route.
Ah,Damn.
That’s a pain. I think I’d sooner return it to the retailer for another one than go to Wahoo.
In the UK your contract is with the retailer rather than the manufacturer so doing the above is “usually” not an issue. Though some retailers try to defer the responsibility back to the maker.
If the chain on your bike is worn and the cassette is new it can cause some vibration. I had this issue on my Core and swapped the chain and was good to go.
Fortunately, I still have the 2017 Kickr. It works like a charm albeit the high pitched sound which is normal for that model. Hope the issues with 2018 Kickr (much more silent) are solved.
Chain and cassette same mileage unfortunately mate. That said I am going to try a second bike on the trainer just in case as it’s the next logical step to make 100% sure it’s the Core and not the bike.
I’ll update on here once I’ve done that.
Thanks guys.
The flywheel definitely has a wobble, you can see the distance between it and the trainer body increase and decrease as you spin it. Tiny amount but it’s there.
Took cassette off and fitted my mtb to the Core. 1x12 Eagle drive train (shim fitting NX cassette) and the vibration is still there under load but NOT whilst coasting, which I find odd?
Just finished the first ride on my second Wahoo KICKR. The first one broke after four rides. 
The warranty process with Wahoo was easy and I got my new trainer quickly. I had to pick it up from the shop by myself, which meant two hours of driving, but that was fine.
According to the serial number the new one was manufactured late July, 2019. We’ll see if it helps anything.
I was once again happy that I always have a backup for all my “important” devices: I was able to continue training with my KICKR Snap while waiting for the warranty replacement.
How do I ascertain the manufacturing date of my Core from the serial number my friend?
This thread contains an old post that describes the logic for the KICKR. The serial number of my device starts with 011930…, which can be translated as the week 30 this year.
I have no idea if the same logic can be used with core.
