The first over-the-air update for the Specialized Levo 4 goes live today, 17th February 2026 . It bumps peak power to 850W on S-Works and 810W on standard models , smooths out the speed limiter transition, and refines overrun behaviour.

Try harder. From MTBR directly:

I can also go faster on my Sur-Ron, not even having to pedal. I have ridden both bikes and preferred the Levo prior to the power upgrade, its just a way better ride. If power is your only defining metric for an eMTB, congrats! That gap just closed considerably. ;)

You're missing the point : I was responding to the linked benchmark/comparison, which is inaccurate and incomplete, which has been confirmed by the individual who actually did the testing. That's all. My KTM 300 is faster too. Not the point.

Again, did you watch the video as he literally said that the Amflow had the 1000watt option but was tested at the previous lower power setting of Amflow (850 watts). So what did you miss?

Seems like 850w compared to 850w is an acceptable comparison.
The spamflow riders will not like this result. We should hear something shortly🥱
They will say he was pedaling harder… or something, so the depreciation on their fine DJI rides slows down🤑🤣🤘🏼

Not only did it seem fair but the numbers are what should stand out, 1.2 mph (average faster) at same the 850watts . What do you think that 150watts remaining from the Amflow will net it on the climb? Diminishing returns the faster you go....
 
Yes, he tested the Avinox at the 850W setting, true.

All these motors in the full power market are great, so who cares. Specialized now releases their power bump for their owners and they can do it via their phone…. Awesome 👍. Everyone should be happy. With that being said, Specialized is making a huge mistake by separating the level of bike purchased as to what upgrade you have access to. Not a good business decision from a customer standpoint IMO.
 
dont get me wrong the updates a great thing, but in reference to the amflow comments is this all emtb is now ? whose got fastest motor to get top of hill?

My ebikes still got more power than my legs and thats what matters when i take my emtb out, not turning round to my mates and being like I GOT TO TOP FIRST CAUSE MINE HAS MORE POWER.

Rider power and skill makes at least as much difference. And beyond power, bike balance and geometry, tires, power delivery and controllability all play a role. But Francis’s test was all about climbing speed with equal rider input.
 
Today I did another test ride with the new firmware update, all done with Dynamic Microtune 0/100 (which I really like) to see if there was any improvement in fuel consumption. I started with 80% and reached the top of the climb with 30% less. But it's the feeling of this assistance that I like most of all, I really think I'll use only this from now on; sure, you have to put in some effort, but the motor's response is excellent, even on steep climbs where you obviously need to choose agile gears and adopt a more muscular riding style. Personally, I'm very happy with this update. Well done, Specialized! You've given me the bike I wanted.

That a great numbers, round about 40km with 3000hm in this Mode possible
 
There is an Update on that ˋsoundˋ issue. Seems to be ˋby designˋ however they also seem to plan a deployment for refinement.

https://support.specialized.com/kb/...00000006201/Turbo-Bikes-Motor-Sound-Explained

  • ℹ️ Walk Assist Sound Change with Levo 4 Firmware Update
    With our most recent Turbo 3.1 firmware update (released February 17), some riders have noticed a brief “electrical” sound when Walk Assist is first engaged. This sound lasts for only the first 1–2 seconds, does not occur during normal riding, and is not a sign of motor wear, damage, or a warranty issue. Please see our support centre article for more information.

    What you’re hearing is simply the system initiating Walk Assist with updated control logic. We know the sound can come across as “mechanical” or unexpected, but the motor is operating exactly as intended and remains safe and fully reliable.
  • We already working on refinements to make Walk Assist engagement quieter in a future firmware update. There’s no need to roll back firmware—your bike’s performance on the trail is improved with the current version. Ride on with confidence and use Walk Assist as normal

ℹ️ Walk Assist Engagement Sound
With this firmware update, you may notice a brief 1–2 second sound when Walk Assist first activates. This is normal system initialization and not a performance or warranty concern. A quieter refinement is in development. Full details: Turbo Bikes: Motor Sound Explained

Rode mine today a lot better battery consumption, mostly used auto -

Did a hill race with my mate on amflow both hit limiter quick he was still slightly in front but not as much. I had to put in way more effort than him to get the power tho.

Motor seems quieter as well but not sure if that’s in my head.

Apparently is 750watt at the rear wheel which is what Specialized is claiming with 850watt at the crank. So just bad luck for Bosch

No way are you going to lose 100 watts from the motor to the rear wheel. My Stumpy Evo loses 5 watts through the chain measured from the pedals compared to the rear cassette. More drag on a e-bike motor but not 100 watts.

Bosch stays within the 750Wh limit which qualifies their motor to race which is why they have 90% saturation. As far as I understand if your bike exceeds the 750Wh rating it does not qualify to race. Correct me if I’m wrong.

If you go back to post #16 you will see this discussion is already finished

What limiter? Thermal?
 
I'm asking anyone who's tried the new firmware: when you stop pedaling, or when you shift gears and start pushing the pedals again, the motor engages rather forcefully, causing the ebike to leap forward a little. Does this happen to you too? It's not a major issue, but I'd like the engagement to be more gradual...

Which mode are you in? The way you describe your experience doesn’t jive with what I’ve felt. I had stock eco settings and over run set to low. It was very smooth.

I noticed this feature with the dynamic micro tune setting 0/100
 
I also noticed another behavior of the engine which, incidentally, was also detected during the test by the E-mountainbike magazine:
"The only real drawback – even after the update – appears when approaching a climb at high cadence. In this scenario, the S-Works 3.1 has to dial back its support slightly towards the upper end. It’s far less noticeable than with the Shimano and MAHLE drives, which tend to drop off more abruptly, but it’s still there if you’re riding aggressively with a fast cadence".
 
Have now 4 good long rides with the update. Battery consumption is nearly the same. My usual 16 mile, 2100 ft, 1:20 loop in Turbo 100% of the time used to result in ~44% battery remaining. Now it's maybe 42%. I have no idea how they delivered 22% more power while mostly retaining identical battery consumption. Kudos to Specialized's engineering team.

I have similar thoughts about motor noise as @Ribinrobin. Seems like somehow the motor makes less noise under certain conditions. Even my action cam footage backs this up.

This fact is clearly established by the following footage from yesterday.

I have never seen a smoother trail. Honestly.
