This forum is for discussing anything related to the Avinox M2S and M2 drive systems. Feel free to ask questions, leave helpful tips for setup/tuning/service, or provide notes about how the motor has performed for you.
Avinox debuted its M1 drive unit with its own AmFlow bikes in 2024. The M2S and M2 drive systems take things up a notch, offering more power, less noise, more efficiency, and similar weight. The systems are also being specced on an increasing number of bikes (list below!).

Whyte also announced their new M2S-powered bike today, although it's a bit less real at this point and will only be actually available this summer. Here's the info we have:
Commencal has also joined the M2S party with the Meta Power SX Avinox, which looks like it should tick a lot of boxes for the e-enduro crowd (although it is a bit heavier than many other M2S bikes launching today):
Highlights (from Commencal):
The META POWER SX AVINOX combines performance and strength with excellent handling and manoeuvrability. It's designed for those who want long rides with a powerful and torquey motor. Complete with 160mm of travel, the suspension benefits from our Virtual Contact System (VCS) linkage. Low in weight and with a 27.5" rear wheel, this bike is responsive and particularly agile.
Build Kits:
More info at commencal.com.
Here's our Flux One Pro dream build with Avinox M2S
I only want more range.
This is where I think Amflow is once again lapping the entire bike industry with the PR or PX. Now you can pick if you want the good looks/less weight of an integrated battery or want the ability to swap batteries mid ride without the brand gaslighting you into a reason why removable batteries are the devil.
Whats the warranty on these motors and batteries?
At 1,100 or 1,300 watts continuous power doesn't that mean none of these ebikes are considered Class 1?
2 years for motor and battery. Battery warranty is limited to 500 charges. I have heard in the past, that avinox requires that the warranty be processed through the OEM brand, and that the oem brand is responsible for managing their own warranty stock for motor replacement (not sure about battery). I can't/haven't confirmed the oem warranty processing requirement, but that was told to me by a friend whom owns an IBD, so take it with a grain of salt.
Propain has a new Avinox M2S bike too, which will be available to pre-order on April 16. Until then, here's a bit of a teaser:

That depends on what we are defining as class one and is it 750w nominal or 750w max. If it's 750w nominal, then a peak wattage of 1400-2100 would not be out of the question while still hitting a 750w nominal rating. If it's 750w max, that is more in line with a 250-300w nominal.
I think the logical break point for class 1 would make sense at 1hp (750w +/-) and my hunch is that is where this will likely end up. The question is then, is that nominal or peak?
a race to the bottom imo.
if anyone wants to go down the youtube rabbit hole, here's a link to "avinox" videos uploaded within the last 24 hours (as of Apr 9 - there are plenty and they all look exactly the same 🤣 ) - https://www.youtube.com/results?search_query=avinox&sp=EgIIAg%253D%253D
Correct me if I’m wrong, but “nominal” is effectively meaningless right? Each manufacturer can claim whatever “nominal” value they want. As far as I know there’s no formal or legal definition, no formal testing procedure, etc. So all DJI has to do is say their motor is “750w nominal” and it is?
I feel like MTB officially jumped the shark today...
@Blake_Motley did a first ride of the new Pivot Shuttle AMP'd. I had him toss together some additional impressions of the new motor:
I had the opportunity to ride the new Avinox drive system on board the Pivot Shuttle AMP’d that launched today. My limited time was primarily focused on sussing out that bike’s handling, but it also gave me the opportunity to get acquainted with the M2S. From the first pedal stroke I was met with an overwhelming level of refinement. This system is capable of producing a hilarious amount of torque on a dime and can do so while delivering unparalleled traction control. The customizable OLED touch screen display and wireless mode selectors add to the overall experience. The Avinox App, which is mandatory to pair to the motor in the first 100 km, gives the user free reign to customize their bike, including setting the rear wheel size and exploiting various levels of integration, including heart rate and GPS. With the Avinox system now available on way more bikes, there is a clear front runner in the e-bike arms race. No side by side testing with other motors yet but if I were a betting man I’d put my money on the Avinox.
Should this much power be handed out freely? Personally I think we’re playing with fire, and my time on the Pivot only solidified that feeling. The consensus among the consumer base appears to be they would rather have it and not need it, than need it and not have it. I empathize with that sentiment—anyone interested in a less powerful bike is welcome to tune theirs down to what they’re comfortable with—but it puts a lot of faith in the same people you share your morning commute with. What struck me on the M2S was how effortlessly I could reach 20mph going uphill. All it takes is one head on collision between two of these before the proverbial legal hammer comes down. I’d like to see an international 3rd party like the UCI step in and clearly define what it believes a Class 1 250W e-bike really is. Even if no one pays attention to e-bike racing and the definition isn’t widely adopted, it gives your local regulator something to reference other than their imagination. Full disclosure: I never tuned down the bike.
Well said. I think it is irresponsible of both dji and brands to say "just be responsible". It's not merely a matter of having the power and choosing not to use it. It's that when its available to everyone at scale, it will cause problems. 1500 watts man...
1500 watts is fully 2.0 horsepower. That’s kid’s dirt bike territory!
These are big step back for the industry. Super lame. Will predictably lead to problems and less trail access. Remember, most trail access is grace, and not a right.
I agree. To much power and weight. I’d take 1/2 the power and 1/2 the weight, in a reliable smooth and quiet package. With a range extender option.
Are charging ports the same in M2 vs M2s?
I see that bikes sold with M2 have a slower charger, so the question is can I buy a faster charger aftermarket to use with a cheaper motor?
That's a lot of eggs in one basket, so other than Pivot, which other brand is offering different models with different motors, at least they, for now, are giving their customers options, personally I'm not interested in power, more range, service support, repair and warranty support, service centres, are all key things to consider when putting your money on a one trick pony
Automotive has done it for decades. Blame the user, not the equipment.
Would you call the automotive policy a success? Cars are also an integral part of the average American’s day. The attitude is that cars are tools and bikes are toys and like it or not the inevitable policy will reflect that. You can get a taste of it by visiting any suburban nextdoor and watching people freak out over kids on e-bikes.
Jeff Kendal Weed has just posted a review video on the new Pivot AMPD, a totally depleted battery charged to full capacity took 3 hours.
The automotive industry and the end user are governed by laws which state that you must have a licence and applicable insurance, failure to have either has huge consequences, more so if you are involved in an accident, there are no such laws governing the power of the new generation of ebikes, I understand some American states restrict trail use but here in the UK we are free to roam, the only restrictions on the Avinox motor is that some race organisers don't allow it, these new motors will cause issues people have yet to consider.
bro, my measly ep8 eats drivetrain components like the cookie monster. We are gonna need D.I.D 520 sized dirtbike chains on these things soon. That is ridiculous power.
Using WD40 for lube or what? Haven't had that experience myself. I went though I think 2 XT cassettes/sprockets, and a couple chains over 5 years on my Ep8 bike, nothing that crazy. Modern drivetrains are more than capable of handling these torque levels.
I just checked, this ep8 done nearly 8000km's now!
I think I'm on my 4th cassette/chain. That's pretty good. But this avinox is another league of torque. Can a mtb chain/hub pawl withstand that abuse? Time will tell.
Did they fix the rattle on the new versions?
