Are you sure? Because I've seen people running this motor over 150 phase amps continously without any issues.Hello, the continuous phase amps for QS90 is 40A.
What is the KV for the QS90 please?

Yes, though still in testing not yet in a vehicle.Anyone running 24s to a qs138?
Hello, my typing mistake. The DC current of QS90 1000W motor is 50A as max and the phase current should be 100A as continuous phase current. 150A phase current is no problem but the motor maybe in high temperature. The rated RPM of QS90 is 2900 RPM and max. RPM is 3500. So the KV is about 40.2 for 2900 RPM@72V.Are you sure? Because I've seen people running this motor over 150 phase amps continously without any issues.

Since the shipping cost is high which ship from China, if you order other product like motor or controller together, the shipping cost of USB cable for EM150 controller will be shared and seems lower. If you have any inquiry, pls feel free to contact me.where can I buy cheap programing cable and wiring harness for Votol EM150SP?
don't know why, but 50 USD on aliexpress seems a bit too much

Thanks, but I don't think a 6" wide rim will clear my bike's suspension.Hello, the 17x4.5 Inch 12kw-14kw hub motor is not available any more. But the 17x6.0 Inch 12KW hub motor is available. If you are interested in it or any other items, pls feel free to contact me. alan@siaecosys.com
You're welcome. The 17*3.5 Inch in wheel hub motor QS273 series are also avaliable.Thanks, but I don't think a 6" wide rim will clear my bike's suspension.
Hi Alan and the QS Team,You're welcome. The 17*3.5 Inch in wheel hub motor QS273 series are also avaliable.
Hello, after watched the videos, in the first video about Super Soco, I think it's our QSMOTOR QS273 series. Maybe 17x3.5 inch. Because the side cover of the motor is similar to ours. If there is a serial number from the motor could be checked, we could confirm it 100%.Hi Alan and the QS Team,
What kind of high power 17 inch rim wheel hub motors do you have over 12kW continuous? Please watch this video of a hub motor in the Super Soco, is this one of your motors, is it a Yuma or some other competition?
What other hub motors do you have today with a stator width of 60mm and over, either with a 5.00 rim width on an aluminum wheel or a hub with 36 spoke holes?
Any idea which QS 266 hub motor is in the following video? If the number is right, this should have a rotor width of 260mm and 60mm stator laminations width, but it does not look like that in the video.
I am also interested in your 1081200 and 1081800 controllers, but they seem to be quite expensive compared to American and European controllers. Even the Chinese competition like Golden seem to have less expensive controllers.
Hello,I could share you with it.does anyone know what type of connectors are on Votol EM150SP for wiring harness?
Hello,TomyCan you share what is the type/name of the male connector that plugs in EM150SP?
I looks like molex microfit, but it looks like it has some added plastic around it for waterproofing
Or where can I buy male connectors to make my own wiring harness?
I have attached image of the connectors that I need.
It's the black connectors, 6 pin, 8 pin and 16 pin ones.

Hi,
I am looking for QS motor for my enduro style e-bike build (EBB frame) I'm looking for it on a 26x4 Fat Tire and wheel with a 150mm dropout.
I was looking at 2 motor variants
QS205 50H 5T
QS273 40H 5T
I have a question about freewheels.
I was told that there are different thread sizes between the QS205 (English) and QS273 (Metric)
As far as I know, there are 5 different standards.
out of the 5 standards which one are they?
Type Inch Metric Italian 1.378" x 24 tpi 35 x 1.058 mm ISO 1.375" x 24 tpi 34.92 x 1.058 mm British 1.370" x 24 tpi 34.80 x 1.058 mm French 1.366" x 25.4 tpi 34.7 x 1 mm Metric BMX 1.181" x 25.4 tpi 30 x 1 mm
I would like to have more gears if I have electrical issues and need to pedal back like a regular bicycle.
I've seen the QS205 with a single and 7-speed setup and a QS273 with a single and 3-speed freewheel setup. I'm also wondering if I can get a 7-speed freewheel to fit on a QS273.
Hello,If I were to guess. ..
English thread = ISO
Metric thread = Metric BMX
But I could be wrong.
Could someone please verify?
I messaged QS motor and they still haven’t gotten back to me. I’m sure some one here knows.
That means it is *not* "english" threads, but is a "nonstandard" Metric.Hello
The thread size of QS205 is M35x1.5mm in English.

Well this answers my question I cannot get or find a 7-speed because of the non standard thread sizes used in Qs motor.That means it is *not* "english" threads, but is a "nonstandard" Metric.
ISO, or "British / English" freewheels use 1.375 x 24 TPI.
(technically the B/E are teensy bit smaller...but the term is used often enough to mean the same thing you might not know which one some non-branded freewheel actually is).
