Avinox M2s rattle

[EbikeDoctor]

I just made a quick video, how my m2s sounds, but in trail with the Amflow frame its amplified a lot.

100% every M2s will have movement and some level of noise like that, zero noise would mean zero movement in the gears and serious tolerance issues and wear. Some might exhibit a bit more than others and even show more when hot, but 100% every motor will have some degree of movement. Complete lack of movement would indicate a binding gear system.

For anyone else wondering, a friend decided to send videos to Avinox support of the noise made by moving the chain ring back and fourth to expose the freeplay in the motor (as per the video on page 1). All our motors in our riding group have this to some level (M2 and M2s). And the response from support was this was normal, all motors (including the M2s) has some movement between gears, no movement would indicate too tight tolerances. So if you did get a motor changed under warranty expect a new one to be the same/similar.

Did you friend have the M2S motor? There will always be play with spur gear motor engagement and going about this way with Avinox Support, it's not surprising that they are coming back with a normative response. There is wiggle room (NPI) here with the M1 and M2 to say that's life, but not the M2S, as it was specifically designed to remove rattle. If the motor rattles while riding, it should be a warranty issue.

M2s, it doesn’t rattle when riding like the m1
Did, but that play in the gear set can invoke occasional noise from pedal kickback pulling on the gears. The M2s design cannot remove all rattle, any free play in the gear set can be invoked by kickback. The m1 could rattle without kickback, just from trail bounce on my old bike, that’s what the new design does, prevents free play induced rattle, but not kick back induced noise. Despite the marketing saying kickback noise had gone !.... not great in that respect

 

[Pedalerie]

We will see about that...and again: Avinox said in a marketing video they eliminated the sound completely. So do a couple of reviewers. Question is, how many km they rode this motor. After changing to a new motor, I will keep you updated about the noise.

If you are right, this is a huge joke and I would be very disappointed. Then what is the mesh gear is all about?

I agree, I was expecting silent motor as you say what is the dual mesh for if not to stop kick back !

That noise is really bad.
Not even may old gen 4 today 35000km old, makes such a bad noise.

Have you submitted a warranty claim? "Normal wear and tear" would not be a defensible counter-claim when it comes to the M2S specifically.

Are you having a rattle-related issue? If so, please elaborate on the details: miles until occurrence, amount of slop, etc. If not then go to the Avinox support threads. To answer your question, it has to be Crestline you go through. If they sell that motor system to you then they have to support it. May not be the hand-holding LBS experience, but that's the consequcne of the direct model.

Rattle since the very first ride, bike has maybe 5 miles on it. What is the link for avinox support?

So here is a video of my brand new M2S Rogue before it's maiden voyage. It has zero rattle and zero gear slop/play. This will be my baseline from which to compare again after I put some miles on at various stages.

I think you should try to wiggle the chainring a bit forth and back ...

I think you should try to wiggle the chainring a bit fort and back ...

I grabbed and wiggled the chainring and effectively did that, but I don't have 3 hands to take the video. Besides, as you can see the chainring dead stops after I let off the crank. I'll post another video when chain is mounted.

 

[Ndanger]

In the "for what its worth" category. I can't help but wonder if the seemingly unexpected delay "or my impatience" if there has been an issue that needed attention and it is the remedy that is creating a delay. Yeah , I am in the "I want it now" mode

That’s not how the rattle works at all, none of them rattle from just turning, you need to grab the chainring and move it back and fourth to invoke the noise. Even the M1 didn’t rattle doing what you did there ! Haha
