MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
circuit - An hour and a half is not too bad at all.
I think it would be hard to determine the maximum fill of copper wire that fit properly in the motor. If I could find a bare stator I would give a 2T a try, and slap it into a 14" rim, or a mid-drive setup.

I had few unexpected wheelie on this motor even with a slight twist
New 16mm axle V3 4t on 26" wheel @40a 20s I get 45mph tops.

Its hard to find dimensions on this motor.
No luck, just the usual caliper measurements (wire, lams d/o's etc) but no motor dimensions.
http://ebikemotor.en.alibaba.com/produc ... motor.html
Seems to be the norm.
Their actual website doesnt list much of any motors.
Anyway trying to force and push my way to knowledgeable success doesn't help in getting motor dimensions while tired and 1am. Seems like a full moon, some little crazy stuffs happening here and there. Not full blown crazy stuff. Combo of Stampede/Drunk ppl perhaps. Will take a break.
Why do these companies like to give package dimensions? I find that funny.
My apologies for my ramblings. Last ditch effort before sleep and I found it. Not under V3, perhaps its a V2 or V1 motor. Same dimensions though.

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
Got my hands on a Mxus Turbo. Did some measurement.
This is in a 165 mm dropouts and perfectly centered to within 1 mm of the center of the spoke flange.
This gives me 21 mm of axle space on the freewheel side.
It gives me only 12.5 mm of axle space on the disk brake rotor side, or 7 threads of engagement.
Do you think 12.5 mm or 7 threads of engagement are enough to hold it secure on that side? Remember, most of the threads are cut off.

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
Because these are clamping drop-outs, I suspect you will be fine.
Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
Dont people spread arms by 4-8mm? Can you not compress just the same?
GEARS? Where we're going we dont need gears!

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
The first two threads aren't properly formed, so really you have 5 threads (and m16 nut is 14mm+ thick) and considering the partially threaded nature of the axle its threads will almost certainly fail before the ones in the nut. However, what spinning magnets said
Clamping dropouts don't need nuts 


Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
I actually didn't count the last couple of threads, so it was a conservative 7 threads. What I could do is offset the tire maybe 2mm to get maybe 2 more threads, and that would make it a little better.
I think if you compress your dropout width then it wouldn't grab the axle spacers at an angle. Not sure if that would be good, but it would probably work.

How about a nut both sides of to get lots of extra contact area with the frame and might need less nm.
If I was desperate and knew the hub was only ever for a 165mm frame I might tack weld the nut on the end and use a nut on the inner side to lock the wheel.
My slim axle always eats into the frame on the side with no torque arm. It must twist slightly. My 16mm axle mxus will hopefully not do this

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
forget to squeeze the dropouts.
if you do it, you never get your calipers parallel to your disc.
2mm and you can fight hours to make your brake not scratching the disc.
found that out really late. just fuckin 2mm spacers added to my dropout and after some minutes the brake runs without scratiching.

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
Isn't the mxus v3 turbo supposed to fit 135mm dropout?
Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
We special order the 3K-Turbo with 135mm axles. Normally they are 142mm.cwah wrote:Isn't the mxus v3 turbo supposed to fit 135mm dropout?

How about the brake caliper on 135mm drops, will it fit?

The brake side of the axle is the same as the 142mm axle. We just shortened the freewheel side by 7mm. Result is that you can't use more than a 5-speed freewheel. Otherwise it's pretty much the same geometry.Allex wrote:How about the brake caliper on 135mm drops, will it fit?

Thx, do you know if the older mxus v2 had 142mm or was it actually 135mm wihout the spacers?

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
We could special order this axle width, if there is enough demand. (Requires a 100 pcs axle order with MXUS).BeachRider2016 wrote:Theres no 149mm or 150mm dropout ? Wonder why

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
If I had a hubmotor business, this is how I would do it. By making the axle-shoulders "just right" to fit into common bicycle drop-outs (at 135mm), and the torque arms are on the outside of the frame. At that point, these axles will fit a thousand different frame models, and the extra axle length can be easily cut if desired. However, the extra axle length is needed depending on how thick the torque-arms are. If aluminum, they will need to be fairly thick. Axles can be cut, but can't be stretched, so...extra length is the right choice for a vendor.The brake side of the axle is the same as the 142mm axle. We just shortened the freewheel side by 7mm. Result is that you can't use more than a 5-speed freewheel. Otherwise it's pretty much the same geometry
Its always funny to me when someone who wants a hubmotor that is capable of 3000W-5000W wants to have a lot of gears available...If you want 750W, get a geared hub or mid drive, if you want 1000W-2000W, there are cheaper and lighter DD hubs and mid drives available.
But...once you ride an ebike with 3000W or more? for some builders, that become their minimum standard. If that sounds like you, then...asking for more speeds than two is ridiculous. Use the smallest available single-speed freewheel, and then maybe swap-in a two-chainring BB crankset with a chain tensioner. One gear is the "I want to pedal along in the lower half of the motors power band"...and...the other gear is "something went wrong, and I have to actually pedal home with no power".
Asking for a cassette freehub or anything more than a 3-speed freewheel is something that those low-powered DD hubmotor owners do. The stock 3000W MXUS DD hubmotor is awesome, and the "turbo" version sold by Kinaye is "awesome plus-1". Barent is just being polite. Take my advice, if you are in the market for a MXUS 3000W Turbo? Feed it a lot of watts, you won't regret it. And...if you're feeding it a lot of watts? you don't need a lot of gears.
Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
The only reason I got a 7 speed on my mxus 4t was to gain an 11 tooth cog and keep bigger gears for problems. Like when 2 cells died 10 miles from my destination. It was mostly uphill and would have added 3 hrs to my journey If I hadnt had the 20-24t range.
I wish they made a 5 speed with 11-24 or something because squeezing in the 7 speed block was a PITA.
But yes, I only use two gears.
13t for cruising at 20mph near people or up 15 percent gradients.
11t for everything else (40mph max).
I have a 42t or 44t up front and my front derailleur has seized due to lack of use ha ha
I run 56-76v at 60a dending on the range I need that day.

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
Does anyone know why the MXUS does not center in dropouts if the axle is centered? Is this done on purpose maybe to give more room on the freewheel side for gears?
I believe most hub motors are not centered when the axle is centered.

Probably is like regular bike hubs, offset to clear freewheel cluster.
At least you don't have to rebuild your frame or grind the flats further towards the motor to use it.

Re: MXUS 3K Turbo (V3) 45mm Direct Drive Hub Motor
hi there and sorry in advance to nitpick..
the OP states 20.6 lbs for V3, I thought I had read 28.6 lbs elsewhere, but that could be shipped. is 20.6lbs the real motor weight?
