Hello, just to let you know there is an easier way to remove the flywheel. Remove the plastic center cap on the flywheel by pulling it out with adhesive. It will expose a nut. Use a 19mm socket wrench and hit the wrench sharply to remove the nut. It has standard threading (CCW to loosen). Then you can pull out the flywheel. Done. you will still need to remove the belt to do balancing in-site but above method will not risk damaging the cog.

Hi there, yes, you are totally right. Sorry I've been late to get to this but it seems recently more people have been watching this. I added a note above. Note though that removing the flywheel this way does not allow you to do balancing quite the same way as I found that the flywheel never sits in exactly the same way when reattached from the nut side, but with a bit of patience, it works just fine.

I was asked about the ‘belt’ technique to undo either the nut or cog. This stops the flywheel spinning... there’s a lot of torque on the nut. Basically take a leather pants belt and loop it round the flywheel, then tie off the loose end around one of the legs. If you’ve done it right the belt tightens as you apply force to the nut, and the flywheel cannot move.

Thank you for sharing ! I just brought a Kickr as well. Second hand from october 2017. I immediately experienced some low frequency resonance with my room/floor (solid concrete, 1st floor) on some speed. It's just incredible. I can't use it like that, my neighbors will go crazy ! So I started to play with a small coin under a 5cm piece of duct tape. I stick it directly on the flywheel. But I was never better, always worse. So I thought it was too much weight. I then tried only with this piece of duct tape. Luckily I've quickly found a good spot and vibrations level is now reduced. I'm surprise the fly wheel is not more carefully balanced at the factory. (Maybe it is, I have no clue) The ratio on the belt drivetrain is around 8. On 52 x 15 gearing it give a 3.46 ratio. Spinning at 90 rpm gives 90 x 3.46 x 8 = almost 2500rpm for the inertia wheel ?!?! I think I'll go further in the balancing process. It's a same we don't have a through axis, we could do this then : kzitem.info/news/bejne/l5uHr3aQcnt0dqQ

Apparently, I was dumb. there is a much better way to remove the flywheel that someone else commented on. Remove the plastic cover in the middle of the flywheel to remove it from the shaft.. however this might make the balancing process difficult? Maybe this is the right way. The critical part I think is removing the belt to figure out where the mass needs to be, then once you have that, you can play with the mass.

I recently purchase a 2018 Kickr to replace a 1st generation Kickr I have been using. The unit starts to have noticeable vibration around 20 mph(during a ride or spin down). It leaves me with serious doubts relating to quality control and testing of the final assembly. The 1st generation had no vibration and quite a bit of belt noise. The new unit does have a considerably quieter drive train.

Thanks for this Daniel. I just received a V4 KICKR and there is an interesting difference in the design compared to your V2 version. As you might know, the V4 KICKR now uses a micro V belt that makes the unit silent. Unfortunately, my unit has a couple of problems. The threaded design of the small cog, that is clearly visible in your video, has been changed to a “woodruff key assembly”. The small cog rotates at high RPM, so any movement here is amplified and can causes a clunking noise, as it does with my unit. I am however pleased to say that WAHOO are addressing the issue and my experience with their support so far has been good. Another slight problem with my unit is a slight imbalance in the fly wheel (i assume). Thanks for showing us the inside of your KICKR, as it is good to know that there is way to improve the balance if needed.

I've had four Kickr 2018s (V4), and three of them have had this same vibration problem.There's been threads of people taking about flat-spotted bearings because of high belt tension, but I suspect the issue is really this flywheel imbalance. The woodruff/bolt fix is related to this, but does not fix the high-speed vibration. So far, Daniel Fletcher's videos are the only mention online of this vibration I can find, which seems odd. Wahoo just sent me a replacement Kickr two days ago that was supposedly "inspected" by their techs and already had the woodruff key/bolt fix applied, but it still vibrates.

This fourth "fixed" replacement is the only one I've had with the updated woodruff key/bolt.

Hi, it's a standard thread - leftie loosey, righty tighty! I would recommend removing the flywheel on the flywheel side instead (thanks to a contributor below). Remove the central plastic cover and remove the nut with a large box spanner. A good trick to get the leverage you need and stop the flywheel from rotating is to use a belt to secure the flywheel to the frame.

Good tip about the belt as stopping the flywheel rotating was impossible. Just brute force in the end :) I tried going in from the flywheel side but you can't get the bearings out that way. Anyhow, bearings changed, flywheel balanced and hopefully good to go for a few more years. Thanks again for making this. There is zero other info about getting inside the 2017 Kickr so this was a life (and wallet!) saver. Took a lot more than those two cups of tea though! :D

@@oliverhall1026 The drive side bearing just pulled out by hand. The other bearing is on the end of the axle and was a bit tighter but I was able to lightly tap it off with a hammer and cloth for protection. Definitely doable with household tools and a bit of care. I used a six point socket with a piece of jay cloth pushed in so it wasn't metal on metal. It left no marks or damage whatsoever. I expect a 12 point might be even better as more points of contact. (edit: a 12 point won't work. See Olivers comment below!) I used SKF 6003 2RS which have the rubber seals. The ones that came out were 6003 ZZ. One word of warning - that cog is seriously tight. I was on the point of giving up because i was scared of stripping the thread. What eventually worked was securing the flywheel as much as possible then whacking the socket wrench with a hammer to break the locktite. It's one of those situations where everyone will probably come up with a different technique. It was all a bit stressful and took some perseverance but the result was worth it. My Kickr feels better than when it was new. Now i know what to do I'd have no qualms in doing it again. Just a bit scary first time round :)

@@SirDazzyB Cheers! :-) To anyone else reading, it must be a 27mm 6-point socket, as a 12-point socket does not enage with the pulley. There is only about 0.3mm of engagement with the pulley teeth so you should ensure that the fit with the socket has little or no play otherwise you risk rounding the teeth. Dazzy above used cloth to take up this play, but I think that using a sheet of Aluminium foil folded over several times and wrapped tightly around the pulley might work better as Aluminium foil is roughly the same hardness as the pulley and so it will not damage the pulley but it will also not compress as easily as cloth or tape will.

It's starts to appear when the speed goes faster than about 22 mph so it's happening when I'm performing the spindown calibration. Could the vibration have an effect to the result of the spindown? The power readings from the Kickr Core are about 15w less than from my power meter.
@ginzolacom

It's possible that the vibration will affect the spindown, but then, the point of calibrating it would be to compensate for mechanical effects. However, one thing you have to remember is the drivetrain efficiency (chain, sprockets, jockey wheels). The power meter will be measuring the power at the crank based on the force of pedalling. The kickr, at the wheel... there are losses, so yes, 15W sounds reasonable as a difference perhaps?

@@attejarvinen4776 Possibly.. I would have thought that the losses through drivetrain would be more related to the speed of the chain.. but I could be wrong? You could try changing chainline to see if there is a difference, i.e. running 50/28 against 34/20 would be about the same gear, but the chain will move slower with the latter. If it is the drivetrain, then the losses with the latter would be less. Maybe we're overthinking this. I know power meters are very variable in how much power they report. It's a very difficult thing to calculate based only on force, and not on work. It has to make a lot of assumptions. One think I always fing hilarious is riding with my friends and my Garmin GPS.

how is the unit working out to date? I just bought a Cycleops H2 and it vibrates under load. I am NOT happy as the vibration resonates through the frame as I pedal. Like riding a grinder. The belt is noisy of course but I'm curious if mine has a flywheel balance issue. Probably going to send it back and wait for the mech/tech to mature. I assume these trainers use a electromechanical resistance generated by a magnet pulling against the flywheel in some way? Seems a lot to go wrong.
@ginzolacom

The trainer was fine, then they replaced it. The repaired one I would suggest was slightly better balanced than the new one, but the new one is fine. I don't think there is an intrinsic problem with the design.. it's just a relatively low speed flywheel - engines have much faster turning ones! In terms of how the drag works, indeed, it's an electromagnetic system. The outer shell turning against fixed electromagnets which vary their drag by altering the load resistance. It's a very efficient way of working - unlike a treadmill that consumes hundreds of watts, this system is almost passive. I agree with you, if it vibrates, send it back... it really shouldn't vibrate.
