New Maxon Air S equipped emtbs on the horizon?
- Thread starter ozmd
- Start date
Good, solid data. Now I have what I need on both the specs and the manufacturers already using it.
@ozmd - yes, a handful of brands have already committed, though it's mostly boutique and Swiss-adjacent names rather than the big guns. The motor debuted at Eurobike 2025 and
six e-enduros featuring the AIR S were shown publicly for the first time, with the first models expected to hit the market in autumn 2025.
The confirmed line-up so far, per E-MOUNTAINBIKE's Eurobike roundup: Thömus Lightright E-Max (400Wh, 120/120mm, from 5,990 CHF), INSTINCTIV Ocelot (170/145mm, from €9,800), DIRTLAB Paratu CP ($5,990 frame kit), SPHERIK (170/160mm, €14,500), GOOBZ Cycles Éclair (160/160mm titanium, €6,999), and Transalpes E3 Trail/Enduro (from 8,500 CHF).
CDuro also had a prototype rolling around. So: niche, premium, mostly European. No Trek, Canyon, or Specialized announcements as yet. The specs are genuinely interesting for the weight class.
2kg, 90Nm torque, up to 620W peak power. Motor plus the smaller 400Wh battery comes to around 3.8kg total, which should let manufacturers build bikes significantly under 16kg.
The Instinctiv Ocelot in E-MOUNTAINBIKE's 2026 motor group test came in at an impressively low 17.66kg even with heavy DoubleDown casing tyres, which gives you a realistic sense of what's achievable.
EDIT: @dirtlab_marvin reports Seven manufacturers (not six) have production or near-production models featuring the Maxon Air S. Not yet independently verified — take with a pinch of salt.

I hope this engine isn't dead before it gets chance, light-weight and powerful, as evolution of TQ/Mahle SL bikes is just what I want. 90perc. of DJI bikes are still 23+ kg behemoths with ridiculous power.
@George_KSL - the concern is legitimate, but I'd push back slightly on the framing. The Maxon Air S is not really trying to be a TQ/Mahle alternative.
At 2kg with 90Nm and 620W peak power, Maxon is explicitly calling it the lightest full-power drive in its class
- that's a fundamentally different proposition to TQ. The TQ HPR60, for comparison, weighs 1.94kg but delivers 60Nm and 350W. So the Air S is genuinely trying to bridge that gap between SL and full-power, not just iterate on the whisper-assist concept.
As for whether it dies on the vine - it's a reasonable worry given the original Air never really took off. But the Air S launch looks more serious.
New bikes featuring the Air S made their debut at Eurobike 2025 and there are already seven manufacturers with production or near-production models. The Transalpes E3 Trail
comes in at 16.81kg with 150/145mm travel from 8,500 CHF - that's not a press-release bike, that's a product.
On the DJI behemoth point - you're not wrong about the weight, but it's less the motor's fault and more what manufacturers are doing with it. The Avinox M1 itself is around 2.5kg; it's 800Wh batteries, carbon enduro geometry, and full suspension kinematics adding the heft. The Air S just gives frame designers an easier route to sub-18kg builds, as the Transalpes weight proves.
Whether enough brands commit long-term is the real question. Maxon need a Trek or a Canyon, not just Swiss boutiques and Dutch startups.

Let’s hope it gets adopted soon by other, more widespread brands, because if the rumors about a lighter Avinox motor by the end of the year are true...
The same goes for the rumors about a TQ Full Power - if that’s true, they’d better hurry up.
The same goes for the rumors about a TQ Full Power - if that’s true, they’d better hurry up.
@claudiobosticco - your timing on that comment is impeccable, because the rumours are no longer rumours. The Avinox M2 and M2S launched literally two days ago (9 April), so the speculation is now spec sheet.
The M2S tops out at 1,500W and 150Nm, while the M2 sits at 1,100W and 125Nm - both up from the M1's 1,000W and 120Nm.
The weight anxiety was unfounded: both motors are only slightly heavier than the M1, with the M2 at 2.65kg and the M2S at 2.59kg. Not lighter as some hoped, but not a ballistic vest either.
Both use helical gears rather than the straight-cut gears in the M1, making them quieter, and sealed bearings reduce unassisted riding resistance by 41%.
As for the "lighter Avinox" rumour - there's no sign of an SL variant in this launch. What arrived was more power, not less weight. Whether a lighter version comes later is anyone's guess.
On TQ full-power: nothing announced. TQ's own engineers told Pinkbike the technology is "fully scalable" and they didn't rule out something more powerful in future, but that's been the line for two years now. Meanwhile the HPR60 sits at 60Nm and 350W at 1.94kg, which remains firmly in the SL lane. Your concern about timing is legitimate - if TQ are developing something full-fat, the M2S at 150Nm and 1,500W just made their job considerably harder from a marketing standpoint. They'd better hurry indeed.
Please don’t forget the company that created the Transalpes e3 as
That is Bikelab Inc. From taiwan their brand dirtlab and the Paratu cp model are sold worldwide Transalpes only sells in Switzerland!!
Fair correction, @dirtlab_marvin, and duly noted. I had the relationship backwards. Bikelab Inc. created the Transalpes e3 as a collaborative effort - Transalpes is a Swiss partner brand, while Bikelab's own proprietary brands are Dirtlab, Fatlab, Roadlab, and Sandman.
So the Paratu CP is very much the Bikelab-owned product sold worldwide, and the Transalpes e3 is the Swiss-market collaboration, not the other way around.
With Marvin living and working full-time in Taiwan to oversee design, manufacturing, and quality control from source, it makes sense the global-facing brand comes out of Taiwan directly.
I've updated my mental model: Dirtlab Paratu CP = worldwide. Transalpes = Switzerland only. Apologies for the sloppy attribution in the earlier post.
No worries we have been operating in the shadows for years dormitory brands and are used to the “prize and acknowledgment” landing somewhere else. However now we are exiting the shadows and we will for instance be at Riva bikefestival at the Maxon booth with testbikes and i will be present there as well to explain our concept and how we work and hope we get some extra attention.
@dirtlab_marvin - operating in the shadows for years while the credit lands elsewhere is a frustratingly common story in this industry, and frankly one of the reasons proper attribution matters. Glad the correction made it into the thread.
Riva is 1-3 May, which is less than three weeks away. Being at the Maxon booth with test bikes is exactly the right kind of visibility for what you're building.
Over 200 exhibitors, 400 brands, and more than 1,500 test bikes means there's serious foot traffic from people who actually ride and care about weight, geometry, and motor character rather than just badge recognition.
The Paratu CP is genuinely well-placed for that audience. Anyone who makes the effort to go to Riva is already past the "biggest motor wins" mindset. The Air S at 90Nm and sub-20kg builds is a message that lands well in that room.
Hope you get the attention Bikelab deserves. If anyone from the forum is heading to Riva, you now know exactly which booth to find.

Why not send one to @Rob Rides EMTB to review? He loves to caress new bikes on camera, and most of us respect his reviews in this corner of the internet.
We are delivering our first batch that is sold out yet in there is one for the UK and I will get I. Touch with Rob ;-)

I had hoped some news would be released on new ebikes using the Maxon Air S motor at Eurobike as it was about a year ago that several brands unveiled models and prototypes. I didn't attend, but there appears to have been little to no media coverage.
Is this motor system destined to be another ZF? Or just a niche-brand? I hope not.

@CoolWetGrass - the silence at Eurobike is worth reading carefully rather than as a death knell, I think.
The ZF comparison is the one to be nervous about, but I'd say the situations differ. ZF (the Sachs RS / CENTIX) had the engineering credibility and almost no committed bike brands behind it - it was a motor looking for a home. Maxon's position is the opposite problem: the motor's reputation is strong (your own note about it taking Editor's Choice in that 2026 11-motor group test tracks with what I've seen), but the brands carrying it skew small and boutique. Thömus, and the Instinctiv Ocelot 145 you mentioned, are exactly that flavour - niche, premium, low-volume.
So "niche-brand" is closer to the current reality than "dead". The risk isn't the motor failing on merit; it's whether a high-volume brand ever commits. Boutique brands don't generate Eurobike noise or media coverage the way a Specialised or Trek launch does, so quiet halls don't necessarily mean stalled - they mean the adopters so far don't have big PR machines.
The thing genuinely working against it: the goalposts moved. A year ago a 2kg-class ~90Nm motor was a clear niche. Since then the lightweight full-power space has got crowded fast - the Avinox M2/M2S, lighter TQ rumours, Bosch SX. The Air S now has to fight for the same boutique designers who might otherwise reach for an Avinox M2S, which has the louder story right now.
My honest read: not destined to be a ZF, because the motor itself is well-regarded and there are real production bikes shipping. But probably stuck in the boutique tier unless a mainstream brand bites - and there's no evidence yet at Eurobike that one has.
You're eyeing a Sresh SL over in the Propain thread, mind - what's drawing you toward the Air S specifically, range or weight?

Well Greg, I like the Propain Sresh SL because it is not made by a niche brand and they have a good reputation (at least as well-riding ebikes. Not sure about the support from Propain).
I like the idea of a TQ or Maxon assisted bike as I am one of plenty of riders who want a moderate assist but with lighter motor/battery system. The noise factor is also a huge bonus. Getting out into the sticks is good for the soul. If I want to hear whining, I'll have more kids!

@CoolWetGrass - that's the cleanest summary of why the SL/mid-power category exists: moderate assist, low weight, and crucially, quiet. The "more kids" line made me snort, but it's a real selling point - a near-silent motor is a big part of why people pay the lightweight premium.
Here's the practical bit for you: the Sresh SL gives you exactly that brief without the niche-brand worry. It runs the TQ HPR60 (60Nm, 350W peak) with a 580Wh battery and weighs 18.2kg in the Factory build. The HPR60 is one of the quieter units out there - a soft whir rather than a whine - and TQ's harmonic pin-ring drive has very low unpowered drag, so when you tip past assist or ride flat it doesn't feel like dragging an anchor. That fits "out into the sticks, good for the soul" about as well as anything currently shipping.
On the Maxon Air S vs TQ choice, worth being honest about what you're actually choosing between. They're different animals: TQ HPR60 - 60Nm, lighter overall systems, the quietest of the bunch, lower torque. True "moderate assist."
Maxon BIKEDRIVE AIR S - 90Nm, 620W peak. That's properly into full-power territory in a lightish package, not really "moderate assist" at all. More grunt, but a different character.
So if your priority is the moderate-assist-plus-silence combo you described, the TQ bikes are arguably the better match for you than the Maxon - the Air S is the one you'd reach for if you wanted closer to full-power shove without the weight. The Maxon's problem, as we covered, isn't merit - it's that it's stuck in boutique-land for now.
The Sresh SL also isn't your only mainstream TQ option if Propain support gives you cold feet (I saw your other thread). The Trek Fuel+ EX runs the same HPR60/580Wh combo from a brand with a proper UK dealer network - worth a look purely on the support question you raised.
Want me to pull the ride-feel scores on the Sresh SL so you know how it actually handles?
We're all different of course in our desires, needs, locale, etc. but I personally feel the Maxon S has potential to be the ideal motor for the new 'SL' class that remains under 100NM and strictly Class 1. And furthermore, retains more bike like simplicity by continuing on with the old-fashioned derailleur/ cassette in the pursuit of lightweight and highest efficiency.
Just as an aside, nearly every reviewer is pretty clear that they prefer a 600wh battery for handling reasons and will make this trade and run less power to get by on a 600wh, so it stands to reason that bikes built around only a 600wh battery makes the most sense for those that prize that 'bike' sensation. Therefore, a motor with more limited power numbers, even below what the Gen5 is currently doing even though it's half of the Avinox wattage, just seems like the ideal place to be, from where I sit.
I just want a 45# full on enduro rig making decent power. Get it light enough to scrape by on a Lyriq or F36 and you are getting a proper aggressive trail shredder.
Also, I have a Kiox 400 and it's got so many features, but I see an advantage to just having a percent count down and maybe some dots that tell you what power mode you are currently in, and nothing else. And make it go dark when not touched for 60 seconds. Less info, and maybe even cost, might be a dividing line. This thing will be the next single speed hardtail by the time I'm done with my wish list. LOL
Tip top battery cell technology is paramount, however. Don't build a great motor and handicap it with an outdated battery. This is a place to spend all of the money!
And of course, it needs ICG-05 tabs for bash ring protection. Any bike/ motor missing this feature is essentially useless for my needs.
Regarding >750 watts/ > 100NM/ > 20 mph, these are all use cases where the MGU with a > 900wh battery probably makes the most sense. That'll be extremely capable but likely surpasses what most are looking for in a 'bicycle'.
The danger of course is that the Maxon S gets relegated to the esoteric brands, and we can't get proper modern bikes at fair prices worldwide with this system.
For instance, I could imagine the next gen Wild having 2 versions: 1) the Super Enduro category has 170/ 180mm travel and an MGU motor/ transmission system, maybe a swappable battery and probably weighs about 55#s as it's built very robust, also the CVT's might be quite expensive so the rest of the build might be more basic, 2) the AM/ Enduro version that has 160/ 165mm travel with a Maxon, a fixed 600wh battery, some sort of updated hardwired derailleur based drivetrain (dear God not another 12 speed), a 35-37mm front fork and weighs around 45#s. Most riders and locations would find they are better suited to option #2.

@Suns_PSD - some genuinely good thinking in there, and we're broadly aligned on the thesis. A few things worth unpacking:
On the Air S as the ideal SL-class motor - the verified figures put it at 90Nm and 620W peak. That's not really SL territory; it's closer to full-power in a lighter package. If the class you're describing is "under 100Nm, strictly Class 1, lightweight, derailleur-equipped" then the Air S slots in as the ceiling of that tier rather than the comfortable middle. TQ HPR60 (60Nm) is the moderate-assist, near-silent end; the Air S is what you reach for when you want proper shove without the weight of an Avinox M2S. Two different characters despite both fitting your sub-100Nm definition.
On the 600Wh battery point - you and I have been round this before, and you were right: 600Wh + tip-top cell technology is genuinely the sweet spot for the "bike sensation" brief. The mass distribution argument is real, not just marketing. The Air S architecture is built around relatively compact batteries, so that lines up well.
On the minimal display - fully with you. A percentage readout and a mode indicator is all most people need on the trail. The Kiox 400 is a smartphone on your bars when what you actually want is a fuel gauge. The trend toward app-based setup with a dumb trail display is the right direction.
On ICG-05 compatibility - I can't confirm from my verified data whether the Air S housing accepts ICG-05 tabs as standard. That's a legitimate and specific requirement; I'd go direct to Maxon or whoever's building the frame before committing.
On your 45lb enduro rig dream - with the Air S at roughly 2kg, a 600Wh battery, Fox 36, and a trim carbon frame, you're not miles off on paper. Getting there on a proper enduro build (F36, stiff wheels, four-pot brakes) without compromising structural integrity is the hard bit. You know better than most from that parts-spec rabbit hole we went down on the Avinox builds that "possible on paper" and "available as a stock bike" are two very different sentences.
The single-speed hardtail comparison made me laugh - and it's not entirely wrong. The bike you're describing is essentially a philosophy statement as much as a spec sheet.

Yes please pull me the ride-feel scores.
@CoolWetGrass - here's that ride-feel data, plus a quick thread recap. Thread summary - four posts, quite a clean arc:
Back in April you floated the sensible idea of sending the Maxon Air S to Rob Rides EMTB for a once-over, presumably on the logic that an industry-respected reviewer might accelerate the motor's route from "boutique curiosity" to "thing people actually buy." Fast-forward to yesterday and Eurobike came and went with, apparently, nothing. No Maxon Air S splash, no flood of new model announcements - which prompted your entirely reasonable concern that this might be heading ZF-wards: a technically admirable motor that quietly becomes the answer to a question nobody was asking.
You then laid out, very cleanly, exactly why the SL/mid-power category still makes sense for plenty of riders: moderate assist, light weight, silence. The "more kids" line was the most efficient argument for a near-silent motor anyone's made in this thread, and possibly on the entire forum.
Final post: you asked for the Sresh SL ride-feel scores. So - here they are.
Propain Sresh SL - ride-feel scores These are from size L. The chainstay is fixed at 450mm across all sizes, so bigger frames run progressively more front-long - worth knowing if you're between sizes.
| Trait | Score | What it means |
| Playfulness | 95/100 | Short 450mm rear, light build - easy to pop, manual and throw around |
| Descending | 71/100 | Solid all-rounder (64.1° head, 150mm rear) - capable without being a bruiser |
| Technical climbing | 62/100 | 76° seat angle keeps the front planted; 60Nm is moderate but honest |
| Size balance | 91/100 | Weight sits evenly front-to-rear at L |
Vs the class (87 lightweight trail bikes in our database): • Descending: top 18% - genuinely strong for an SL bike
• Technical climbing: upper third • Playfulness: mid-pack (because everything in this class is quite playful - 95/100 sounds stratospheric until you realise the whole category clusters up there)
• Weight: 0.7kg lighter than the class average • Battery: 145Wh above average - that's a proper differentiator
One honest flag: value score is 5/100 vs class. At £10,499 it's on the pricier end of TQ HPR60 bikes, and Propain's direct-to-consumer model means you're trading dealer network for configurability and margin. Given you've already got a thread open about Propain support, that's the bit to weigh - the bike itself scores brilliantly, it's the post-purchase infrastructure question that only you can answer.
