Q: Regarding: Newest 20 inch 48V 1500W rear hub motor – bike conversion kit works on any bike.

What is the max current of the hub motor controller at 48V?
Is the controller programmable to other max current settings?
Does the LCD display show power either in watts, or volts and amps?

A: It’s max 40A
This bike motor controller can set other max speed.
Yes,LCD display power

Q: If I order just the hub motor, can the 1500W rear hub motor have a 10K NTC thermistor installed in it?

A: This 1500w hub motor with 10k themistor (It’s default)

Q: I have a 135mm fork. Can the Shimano Freewheel, 7 Speed, 14-28T be installed on the hub motor and still fit within 135mm?

A: Shimano 7 speed screw-on sporket can be install this hub motor.(TZ-21) – It’s default. Also,fit for 135mm fork.
If other shimano 7 speed cassette sprocket,need to modify hub motor.(We still can make.)

Q: Thanks. Do you sell a Shimano sprocket with an 11 Tooth (11T) that would fit the 1500W rear hub motor?
Q: Can you list the description of each wire in the hall/temperature connector pictured below?

1500w hub motor rpm

Posted by on December 30, 2021 Comments Off on 1500w hub motor rpm

I have done a little more testing with the 1500w hub motor. I think that I am
happy with the current winding. I am giving the motor 65A battery, 180
amps phase.. and it is like a rocket now.
The efficiency is very good.. the most efficient hub motor I have
tested.. good work!

But I want to be sure about the winding for my post about your 48V 1500W bike motor,
because your webpage shows lots of different RPM for the same motor (
this is confusing )..

If someone orders the hub motor from your website.. they will receive a 16*4
turn motor, which is 650rpm @ 49v = 13.26 kV
And the 13*5 turn motor would do 550rpm @ 49v = 11.2 kV
Is this correct…?

P.S. If you are interested in having a hub motor re-seller.. I told someone
in the USA about your hub motors and told him about my tests.

I got the hub motor and have tested it. It’s a great hub motor, but the winding is too fast for a 26 inch,650B,700C,28 inch,29 inch hub motor wheel.It’s better for 14 inch,16 inch,18 inch,20 inch,24 inch bike motor wheel.

The no load speed on the hub motor I received = 640rpm on 49v.

I notice on your web page that you sell stator windings.. I was wondering
how many turns this hub motor has.

Is it possible that you could sell me a stator winding with one more turn that could do 500-550rpm on 49v?

16 * 4T 650RPM
13 * 5T 550RPM
11 * 6T 450RPM
9 * 7T 350RPM
8 * 8T 250RPM
7 * 9T 150RPM
