My px pro’s standard carbon wheels have a super fine engagement hub, I don’t have the specs to hand but it’s the polar opposite for low engagement - if that was a considered tactic to reduce kickback they have done the opposite !

I agree the marketing was pointing to no kickback, but I think that actual statement was taken from the statements someone from Avinox made in a video rather than something written down ?, I might be wrong. My M2s didn’t rattle at all in the fist 2 rides then clearly the grease thinned and...

The anti rattle gear is not on the planetary gears, only on the larger ring gear. The planetary gears have nothing other than a material change and tighter tolerances, nothing mechanical to stop rattle.

Yes, exactly that. All bikes and geometry will invoke that to some extent. My px pro seems to have less kickback when the suspension moves but occasionally it does the odd rattle. Def not like the PL pro which rattled all the time. The point being it’s not a fault with the M2s motor, they ALL...

Yep, 100% i cannot see how they all won’t do this to a lesser or greater extent. There isn’t any anti backlash mechanism on the planetary gears, how can they not make a noise like this 🤷🏻‍♂️

I have yet to see a single motor with genuine no noise at all in the gear train when rocking the chainring back and forth. I you say it’s not the norm but we have more video evidence here of noise than no noise. 🤷🏻‍♂️ I don’t see how the gear train can be silent without being locked solid. The...

You’re not actually doing anything with that chain ‘wiggle’, the rings not even moving mate. Grab hold of the chainring (not the crank arm, not the chain) ideally with the chain removed and move the ring backward and forward. Same as in the other videos on here showing the noise. My guess is...

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

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

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...

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...

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...

yep, I agree, it's very quiet and doesn't consistently rattle on every bump like the m1, and even when it does rattle it's much quieter than the m1

Exactly, reduced not silent. I hold my hand up to not fully reading that before selling my PL Pro to buy the PX pro, and whilst the m2s is def quieter it’s not totally silent. Do I regret the change because of that, no, it’s still much quieter, smoother and more efficient, but any prospective...

They do not say that (totally silent) they say noise is kept below 45 I think i recall - The Avionix M2S drive unit was specifically optimized to reduce sound, with a sound pressure level not exceeding 45dBA. Don’t get me wrong, I would love my m2s to be totally silent, but it’s not going to be...

It will be a mass produced motor in a factory where during assembly a big glob of grease will applied over the gears, that will distribute and thin down slightly after some miles.

Indeed, but as it says… ‘reducing’ pedal kickback noise… not removing kickback noise…

The noise generated in that video is 100% going to appear on all motors to some degree, that is simply backlash in the gear sets which cannot be removed without removing all tolerances from the gears and having a gearset which wont turn. The reason some people hear it after a few rides is the...

I sold my PL Carbon pro once the PX Pro came out and I placed an order, the market literally crashed overnight because of the PR and new motors coming out, a month before I sold mine the same bike was going for 2k more. When someone can buy new bikes with 800w batteries and the M2 (and sometimes...
