Avinox M2s rattle
- Thread starter Rob209
- Start date
Maybe not, but when you can hear the rattle over a cassette and wind noise, you know it's loud. That's just how mine sounds. Like dragging a string with cans attached to it when going over any bumps.
I was bored and asked ChatGPT to count the no of unique users in this thread that had rattle issues, it counted 10. Given this thread is the top result on Google for M2S rattle and Rob's "testimony", I wouldn't worry too much for an average e-MTB buyer.
It’s only been 2 months since release. Reading this thread, I thought there were maybe 3–4 cases, but 10 is a freakishly high number for such a short period of time.
I was curious about the newcoming Wild with the M2S motor, but Bosch Gen 5 is probably the safer bet.

So just got a call his morning and my M2S motor has been accepted for warranty, here is what it sounds like in the stand not under any load.
350 miles on the motor, Amflow have said keep on using it until the replacement motor arrives.

So for me this is absolutely not a rattle issue, it's something else.
Here is the rasping noise when under load in normal riding conditions.

Looking forward to the motor being replaced, apparently it will be around 2 weeks for the new unit to arrive.
Hopefully this is a 'batch' issue and nothing else.
For me I still love the bike and having rode with other people on selection of motors, this is still quieter than most even with the fault.

Aren't you all cherry picking, to notice that Motor rattle?
Between trail noise (Tires/Wheels, Chain Slap, due to rocks and roots), plus the brake noise (not the squicky sound, but yet the Brake Pads rubbing while braking), the suspension noise (hydraulic), and you still notice motor rattle?
Having a CX4, I found the M1 seriously silent!
And after all miles using the CX4, I start not earing my motor rattle, but can notice imediatly any issues (like a loose chain guide).
What were your last ebike motor? Was it more silent that Avinox?

I don't have motor rattle, my issue is different.
My personal experience is limited as this is my first ebike, however even with this rasping issue (that Amflow want to investigate and have warrantied) other motors are a lot noisier
trail chatter does over ride any noise when going downhill, I can hear the Magura brake pads more than anything.
I will check, and yes you are right, because I change a sprocket to 36, and setup the derailleur on 7th cog (red) and I have to setup on 6th (my mistake). Then I will check the rattle...
With the recent verified, raspy motor that didn't rattle how many actually confirmed issues are there. One recent rattle complaint sounds like a dodgy derailleur and is yet to be determined .
Cherry picking, no. Aside from this motor rattle, the bike is near silent going over bumps. There is no chain slap, there is no suspension rattle or clunking, there is no cable chatter and there shouldn't be any noise aside from tire and cassette. So when the motor makes a medium frequency clicking which reverberates through the carbon frame, it's quite annoying. Even more so when the manufacture used the silent nature of this motor as a selling point.

Assuming at this point you've contacted Crestline (or whichever company's bike you are riding) and they have in turn contacted Avinox, what is the formal warranty disposition of your issue? Avinox treating the rasping issue above under warranty does not apply, IMO as it sounds like an unrelated issue and more conducive to warranty care.
Nobody so far who has experienced this rattle issue has come forth on this forum, AFAIK, with a formal response from Avinox on this issue.
I haven't. I'm in the middle of closing a business, handling my late mother's estate, selling a house, selling a building and moving across country while rehabbing from ACL surgery. As annoying as the rattle is, I still have priorities.
Edit: I'm also aware that buying from a small boutique brand may result in a less favorable warranty experience when it's not a component controlled by the bike manufacture. And since I don't really like absolutes without vigorous testing, (even though I'm 98.7% sure it's the motor) I figured to get moved and settled, do some more repetitive testing to ensure the sound is 100% coming from the motor before bothering Troydon with a motor warranty claim.

Quit being so lazy! LOL
Things will get better. How's the knee? I'm 1 week out from surgery and mine still feels worse than when I went in.
The knee is good, after 13 months, it's healed enough to not limit me. The lack of strength in my quads, hams and glutes is what limits me. As soon as they fatigue, all the pressure goes to the knee joint. So it's just working it out, letting it rest,... rinse and repeat. get enough protein and sleep. LoL.
Just got over 4 days with the norovirus though and lost 10.5 pounds in 4 days. back in the gym today though.
Hit the rehab like it's a double black, stat focused and attack as much as possible!

Did you buy your Amflow from a dealer, or direct? And how are they handling the motor replacement? I am curious if they will allow end users who bought bikes direct to do their own warranty repairs if there is no dealer nearby.So for me this is absolutely not a rattle issue, it's something else.
