I woudld think abou a freewheel... There are some posts who said that its quite hard to find one which fits on the QS motor.Mammalian04 said:

QSMOTOR, many of us want to be able to water cool these 205 motors but need more room where the wires exit to fit the water pipes.
Is it possible for you to make a side cover to fit a larger bearing? This way we could use an adapter to fit the cooling hoses like shown in the picture below.
Please let me know if you would consider doing something like this.

Hello Offroader,
Thank you for your kindly information.
We have plan to make water cooled 13"-17" 273 hub motors into Mass Production (not hand made),
which means we invest to open new mould of sidecover and other parts (to fit with water pipes).
Estimated to be ready at the begining of December, 2015.
I think 273 spoke hub motor could be water cooled then, and I will post lastest information accordingly.
So far, we do not have a plan to make 205 spoke hub motor to be water cooling, you might choose 273 motors instead.
In future, we might make 205 water cooling hub motor and let's see.
Attached some water cooled motor for reference.

Hello Mammalian04,
Thank you for your kindly support.
For your inquiry, I will get back to you by pm soon.

Hi Vito.
When you produce these water cooled hubmotors, do you reduce its mass, cause a water cooled hub dont need this much mass to take the heat?
Or do you just convert it to water cooling?
A light weight, water cooled 205 would be perfect.

a qs205 with watercooling would be very popular i think, on this forum anyway.
i for one would be interested in one.

Hello Ridethelightning & Macribs,
Thank you for your advise. It's still too early to talk about 205 water cooled hub motor.
Once the technology of 273 water cooled hub motor is mature,
I will check with our Engineer if we could make 205 water cooled motor, and as lighter as it could be.
Best Regards
I agree with QSMOTOR and was thinking the same. When they get more experience with the 273 water cooling than they can figure out a way to make the 205 reliably water cooled.
I figure we are about a year or two years away until watercooling becomes a standard option for ebike hub motors. Most of us with high power builds will be using them.

The motor I ordered arrived well packaged and spinning it by hand Im impressed with how slowly it spins down for its massive size.
Thank you Vito. Im looking forward to pumping a lot of amps into it.

Hello Offroader,
Thank you so much for your support and sharing your view.
In my opinion, the axle diameter of water cooled 205 hub motor might be much biggner than normal one.
As the cooling liquid is desinged to come out from axle so far. But all depends now for 205 motor.

Hello Luke,
With my pleasure, I am so glad the motor arrived well packaged.
And I am also looking forward to hearing latest news about QS 273 40H Motor.
Please note the Winding: 65X3T-, 48V 807RPM, 16.8kV.
The copper wire cross section is 13.26mm2, we suggest to set 530.4A peak phase current (40X13.3).
Attached similar test report /performance curve "QS 13 72V 4000W 1217RPM V3 Test.pdf" for reference.
If any question, please feel free to contact with us.
Best Regards

Excited much? Is that the 273 motor? What controller will you be using?
Have you ordered Ferrofluid for that motor?
Guessing this could be a new high for hub motor power, what kind of peak kw you reckon?
If you make a thread for that motor, pls link in this thread so we can be sure not to miss out

Yes the axle will have to be bigger, but only a small part of the axle. If you take a look at this picture someone made a small round bracket that fits over the regular axle to make the axle bigger at that one point to pass the water hoses through. A new side cover will have to be made to fit the larger bearing.

Yes as pictured, you keep the same axle and add a fixed bushing to support the large bearing and fit the larger wires and piping. Cover should be able to be machined and bearing support added (screwed and glued) to it.

All, I am working with QS to try and get some 205 motors laced into 17x1.6 rims. I started a new thread about that specifically so I don't clutter their sale thread.

Are you running 17x1.4 with 17x3.00 tire?
EDIT: I am running the Holmes Hobbies 17x1.6 with a 17x3.00 SR241 on one of my Raptors and "I prefer" the look and profile of it. However if the majority of people want the 1.4 wide, I can forgo my preference for the greater good. Of course, this is assuming that QS has a 17x1.4 that they can even get from their supplier for a good price.
I am waiting on their answer to the spoke drill angle so I'll update all in the other thread when they respond.
such heavy hub needs a big tire at least if you place importance on rinding comfort. a big tire needs a big rim, and 1,4" would be only good for maximum 2,5-2,75" or 70mm wide tires.
on my holmes 1,6" rim i run the bridgestone battlax 80/90 17" tire. this is a racing tire with very soft compound optimal for heavy hubs^^
