Totally agree. Over 50lbs is too much. I don’t care how fast you can easily cruise up a fire road. I just wish there were more mid power options that have more DH geo and suspension. . Just my taste tho
I’m almost forced to buy a DJI bike and use a small battery on eco mode. Rather not use a DJI motor.
This one DOESN'T have an Avinox motor. It does have a press release citing [UNDISCLOSED] Nm of torque though! https://www.vitalmtb.com/news/press-release/ibis-launches-all-new-oso-hd-oso-tr-and-oso-s.
I think there’s more to it than weight. I got to ride the TQ Sight and the Avinox Pivot. I think they’re within 3 pounds of one another, both under 50 and despite the Norco having a longer (high pivot) rear end it was still markedly more playful than the pivot. The 800Wh battery stretched out in the downtube makes a big difference in the inertia you have to overcome to get the front wheel off the ground rotating about the rear axle.
The lesser spotted Maxon Air S ticks the lightweight box, no? 2kg motor weight and 90Nm...

That looks very similar to the Fazua motor.
I've never felt the difference of a battery swap back-to-back but lots of people have stated this, even swapping the battery in the same bike, so I'm going to presume that it's quite true.
This is another Con against the high-power motors, as they require so much weight up high to power these darn motors.
Bosch Gen 5 getting 120nm update on 05/04...
I bought one of these in 2018 for $6000 AUD ($4275) the spec was ridiculous, fox factory front and back, shimano di2, saint brakes etc
with double down tyres it still only weighed 22kg. Sure it was ugly as sin, but chucking a 29 inch front wheel on that bike it was amazing.
so 8 years later, we are catching up at triple the cost. ~22kg. The only difference is peak power and 300wH more battery?
yes, it was ugly as sin. But the ability to swap a battery in 10 seconds was nice.
New cooling strategy looks way more robust on the TQ60, giant heat sink on the bottom. Plus bigger 580wh battery should help, sustained battery output seems to be bigger limiting factor. Sorry, 200 but still on TQ50 and haven't overheated the motor. I run the motor nerfed below maximums.
For my home trails I don’t agree with this at all. However… I’m on vacation right now and rode at a place yesterday that has a dedicated climbing trail that isn’t technical at all except for one rain rut. Full power was a waste here and I used half the battery per vertical foot climbed that I usually do at home. Saving some weight would’ve made parts of the downs more fun. I essentially got bored and went back to hang out with the wife and kids.
On this SL subject, had anyone ever tried a hub motor? The Mahle x20 is like 1.4 kilos. Since its unsuspended, is it a complete non starter? I know some people didn't mind the Kindernay( rip)

I'm an E-bike hater, so I'm not too concerned. But have you guys seen this news?
Couldn’t actually read the article without buying a subscription. But I’m not surprised. Have you seen the kooks on big power bikes cruising around the access roads at 25mph or more in Aliso with full on body armor full face helmets chest protectors all Darth Vader style? I’d ban them too.
Some people might not know Aliso isn’t exactly wilderness, more like a big city park.
It's very noticeable in Handling especially the higher up the weight is placed. Levo gets noticeable more sluggish if you swap the 500 for the 700 battery.
The weights seem also to be stagnating thanks to the batteries getting bigger.
As a lighter rider I don't need the additional power. I would love to have a lighter E-Bike tho with a fast swappable battery in two sizes.
Unno updates the Mith with Avinox M2S:
LIFE, TURNED ON - THE NEW UNNO MITH
Let’s get this out of the way first.
Yes, the new MITH makes 130Nm of torque.
Yes, peak power hits 1300 watts.
Yes, there’s an 800Wh battery and a 508W GaN fast charger that’ll take you from dead to 75% in 90 minutes, full in 2h 25.
Cool numbers.
Now forget them.
Because what actually matters is what those numbers feel like when you’re halfway up a climb you used to dread, and suddenly you’re not counting meters anymore. You’re looking for side hits.
That’s the MITH.
POWER, REFINED
The new Avinox M2S drive unit delivers power the way it should feel: smooth, controlled, intuitive.
Less effort. More flow.
More speed, without forcing it.
WHERE SPEED MATTERS
Climbing is a given.
But speed lives on the descent.
When power disappears and only the bike remains.
That’s where the MITH sets itself apart.
Speed isn’t claimed, it’s tested.
In independent testing, the MITH consistently came out fastest on the descents, where motor output doesn’t matter, and only the bike does.
That’s where UNNO stands apart:
Design, kinematics, and ride feel developed to perform when gravity takes over.
12,250 KILOMETERS LATER
César Rojo has been riding the first-generation MITH since day one. Not testing it. Not babying it. Riding it.
Every day.
Over 12,250 kilometers.
More than 460,000 meters of elevation, and counting.
And the bike?
Still tight.
Frame solid. Bearings smooth. Motor and battery performing like they did on day one.
No failures. No hidden issues.
That’s not marketing. That’s miles.
THE UNNO 2026 LINEUP
In 2026, the MITH lineup steps things up where it counts.
At the sharp end, the PRO models come equipped with the new FOX 38 Factory fork, Kashima coating, Grip X2 damper, full adjustability (HSC, LSC, HSR, LSR), 44mm offset. For riders who prefer the feel of a coil, the MITH PRO PODIUM comes equipped with the FOX DHX2 SLS shock, delivering maximum traction and consistency on rough terrain.
Powered by the new Avinox M2S drive unit.
Same DNA. Different entry points.

BOTTOM LINE
You can talk about torque.
You can talk about watts.
Or you can talk about what actually matters:
More speed.
More laps.
More elevation.
More moments where everything just clicks.
The MITH isn’t here to impress on paper.
It’s here to make you faster, and make you want to ride more.

A LOT of news about to hit this thread today...here's an appetizer from Norco to start us off: new Sight VLT Alloy with Bosch PX motor delivering 90Nm of torque, 700W max power, and 400% support starting at $4,799 USD. https://www.vitalmtb.com/news/press-release/your-invitation-emtb-new-norco-sight-vlt-bosch
The only reason the Oso isn’t DOA not being Avinox is because of its absurd amount of adjustability and removable battery. Compare it to the Vala and Regulator with paltry adjustment in comparison and fixed batteries. I’m no Avinox fanboy but I just can’t imagine spending $7k+ with so many compromises and the Oso does not have any of those same compromises.
This is getting a lot of hate over on Rob's forum, but I love the idea. If we are flirting with Surron levels of power, we need Surron levels of range.
If I was looking for a bike I wouldn't let it not being an avinox motor be the deciding factor.
After riding the m2 system I am not immediately thinking oh I need this, I am more thinking how I dont want this. Nor do I want this on the trails TBH.
It's honestly a really lazy implementation. It only fits on L/XL frames IIRC and it's just an adaptation of the other batteries in their lineup instead of a bespoke range extender. They would have done far better releasing a ~400wh version with a better form factor that fits all sizes then to bandaid that onto the bike. I do however agree with you that the power levels are going to demand 1000-1500wh of power, so the need is there.
If you haven’t pedaled a TQ, it feels closer to a normal bike. Newer TQ60 is supposed to very efficient, you can’t break physics a watt is a watt. It’s not like Avinox M2S is drastically more efficient, probably less than TQ. Harmonic ring motor design should have higher efficiency than helical gear system in the M2S for biking parameters. But at the end of the day it’s more about the experience, they are both very different.
Nought-e is out:
DREADNOUGHT E | A New Level Of Confidence
Se we got the e-enduro before the new enduro... https://www.vitalmtb.com/news/press-release/specialized-introduces-levo-4-evo
They definitely should have called it that! https://www.vitalmtb.com/news/press-release/introducing-forbidden-dreadnought-e
It also has surprisingly good geo for an ibis.
478 chainstay on the XL. I think I’m legally obligated to get one of these
Is specialized cooked now that their motor/battery isn't the most refined setup (dji) ?
They've been really coasting on bike design.
Somehow the frame looks visually nicer with 170mm of suspension, but when you see $9k for a new 25kg carbon ebike, it just doesn't feel like you are getting your money's worth. (I know spesh have amazing customer care etc)
We need an electrical engineer to step in here, but I think that there is something related to the rate the power is used that these small battery packs can't provide the power the motor requires. So, a smaller RE would also limit power.
Not talking about the range, but specifically the power levels.
That said, it does look horrible.
Shorter/smaller range extender will be released in future according to rumors. Guessing it is low priority for Avinox.
