Best 135mm hub motor for 48v to 72v ? 3kturbo MXUS OR LEAF

Hello, i just ordered foc controller Nucular, so in the meantime i have a lot of time to investigate some claims, and dream setup for my 26 inch bike. First dream setup was 48v 31.5ah battery https://www.aliexpress.com/item/32840263105.html?spm=2114.12010615.8148356.1.494c31bcRhEzsI, with nucular 12f, and 26 inch leaf motor 1500w cassette edition https://www.leafmotor.com/26-inch-48v-1500w-rear-hub-motor-wheel-electric-bike-conversion-kit-p00096p1.html
. But now i want something like this battery https://www.aliexpress.com/item/4001228148554.html?spm=2114.12010615.8148356.7.5ecd6c29SiwfpF , nucular 12 f , and this 3k turbo. but 135mm.
some subjective opinion i got was this : 3kturbo is the best motor on the Market for 135mm per kv, I'd rather a more efficient higher accelerating 6t, 5t, or 4t 204 45h 3kturbo over a 205 35h leaf bike anyday comparing a 35h magnet to a 45h magnet that's a 28% loss in acceleration at the same kV alone, I don't like the leaf bike axles, they're from the mxus v2 3000watt motors and are prone to breaking on potholes with high speed on hardtail bikes.. The 3t mxus 45h 3kturbo 11.9kv acceleration is almost identical to the leaf 35h 5t, but the 3kturbo 3t has a 15% higher top speed , 3t 3kturbo is bad for 26 , 4t 3kturbo has 17.5% more thrust than a leaf 5t , https://l.facebook.com/l.php?u=https%3A%2F%2Fwww.ebikes.ca%2Ftools%2Fsimulator.html%3Fmotor%3DLeaf%25205T%26batt%3Dcust_84_0.2_18%26wheel%3D26i%26hp%3D0%26cont%3Dcust_120_120_0.03_V%26blue%3DLbs%26black%3Dload%26mass%3D150%26bopen%3Dtrue%26cont_b%3Dcust_120_120_0.03_V%26motor_b%3DMX4504%26batt_b%3Dcust_84_0.2_18%26wheel_b%3D26i%26mass_b%3D150%26hp_b%3D0%26kv_b%3D10.49%26fbclid%3DIwAR03gI148WxynMhvODoih05ngYC_ySpJE5_G7ENuT3LJnZiBHor0z_MACNo&h=AT37yQLKpgaWNP6nSeZn85REKcvgAUgtYjkB5tSf7NxTS-Ag6zLCmmpTkUDotRUiAxDpJkk8EPUm8DOQf1C1IElRshSLg00iqaWXJV9oL2I8YAftdurZe4_h1_DqZ3_DOPtX&__tn__=R]-R&c[0]=AT2QuhYruX5l_RmRsTftDCmPPa5fCqlAYA651C0PL1-E4APe1X1eNaIEp7LBBEVZdiuFzAxdZHpHiTChCYr2Qt5xwDPih7IekM-cmHaxirzHTPjvhTZ0DDcrtm1NuFeTGBHS9YM06HKhRF1dWYWee4oJxHGCE3LL2kyM2MscObeaLQtvjc8qJzj2t1aZfmFL9rzHINV0NeGlc7CV , non of my 3kturbos have ever had problems with freewheels, and i gear them to take a 20t up front and a 16tooth in the rear usually so i can pedal up hills with no power... , the 3kturbo has a 20mm axle on the disc side with smaller axle flats, on the freewheel side it is designed just like the leaf motor , The leaf motor won't be able to pull the full current , I have sinewave Kelly's, I used to use adapttos, I've played with a 6f and 12f nucular, I couldn't find the settings for the IND, it's basically a revamped adaptto from what I saw, if it has the ability to have 2wd and slip control on the front wheel I'd happily pay for a 800amp version and a 400amp version,
I have steered away from sabvoton, they're cheap, but are better than a nucular for the price, I use and sell Kelly kls controllers, I don't use kbx/kbs/kbl/khb squarewave Kelly's anymore due to unreliability and they're for small ebikes with 3kturbo or smaller motors, even for a Mac motor I'd prefer a kls7212s (55amp continuous 120amp peak) for around $100usd
Or a kls7250h (160amp continuous 400amp peak) for 360usd , would like to know if the nucular controllers have timings that change as the voltage drops, as the Adaptto controllers did not and this put them out of business due to most of their controllers blowing up from regen and current feedback at low voltage

So the MXUS melts in 20 minutes?

Question for the forum: Is it odd that a 3000W rated motor will overheat with only 2612W continuous on flat ground? I had to throttle down the settings to 86% before it wouldn't overheat. For some reason I expected the 3000W rating to be continuous.

The muxxus 3k is a more powerful motor than the Leaf. It has more copper, simple as that. But, the Leaf is better made and more efficient. And, I can’t remember, does the Muxxus 3k fit in 135mm ?

They don’t match the same purpose. Many who had built with the Muxxus 3k would be better with a Leaf if they wanted range, or the QS205h50 if they wanted performance.

With 7-spd freewheel it needed a bit stretching (and I cant use smallest cog - chain will hit the arm). With 1-speed, should be no problem.

135mm supports a single speed freewheel, but some ads say that it can fit a 5 speed freewheel
142mm version supports a 7 speed freewheel

4 metres 3000 you should be used in old chromoly frame or something with generous torque arms yeah I get the 3t 142 mm

Does leaf has 2. version axle from mxus ?

Nope, the Leaf motor doesn’t have an axle from Muxxus. If it was your question, which I doubt.

The all up load of 150kg is too much for either of those motors in a 26" wheel. Also, a 4 turn doesn't have thick enough copper to run 120A battery side. That kind of stuff is why you guys melt motors regularly, or magnets come unglued, or halls burn out, etc.

I'm not sure why MadRhino said the Leaf is higher quality and more efficienct, because I seriously doubt it. They have the same stator lams, and with the MXUS having greater stator height for the same end turn losses, makes it theoretically more efficient, since otherwise they're the same design of motor. The thicker stator means the MXUS can make more torque.

Muxus Huxus I bought a 5t first gen steel sator I melted it on hills with stop and go speed bumps. I Now have a muxus v3 4t aluminum sator and don't go up that hill now. It seems to run much cooler. With 15fet 50amp the 5t was on 18fet 80amp @ 72v. Just haven't put the 18fet back on yet. I rather ride than fix a bike.
