26 inch electric hub motor kit for the dropout 160mm fork

Posted by on April 5, 2025 Comments Off on 26 inch electric hub motor kit for the dropout 160mm fork

Q: Are you able to supply a rear hub motor kit wheel (36v @ 500W – 750w) for a rear dropout of 160mm?
I have an existing e-bike that uses a 250w geared rear hub drive on a 26 x 1.95 wheel.
It has a 7 speed gear, standard 160mm disk brake and a bike mount (frame) width of 160mm.
I would be happy to go from a geared (small hub) to the larger electric bike motor kit type.
The existing bike frame is steel (not carbon or an alloy) so I may be able to ‘bend’ the rear forks… (fit).
I have included a PDF diagram (attached) to show the existing rear hub motor fitting size.

A: Yes, we have dropout of 160mm 36V 750W electric bike motor.

Q: With the new Leaf controller and LCD, I know I can limit the maximum output speed of the 750w Direct Drive hub motor to a set (safe) maximum speed for each PAS mode 1 – 5.
With our Australian laws, I want to honor speed and safety – yet have a safe speed and torque (reserved) for hills.
I respect that you have kindly supplied my order with a 320RPM hub motor ( a good choice).
My question is: “Does the max speed by set by LCD / Controller economically limit the maximum current sent to the hub motor”?
I am talking here about battery life with a low speed LCD / Controller setting ‘modulating’ the full power sent to the hub motor.
So if I program the setting to say 25Km/h, then is the torque output effected at speeds less than the given 25Km/h?

A: Yes, if you set max 25kmh by LCD, motor will work less than 25kmh.(You can set max 10kmh,11kmh,12kmh….48kmh,49kmh,50kmh)

1.Press “SW” from LCD. Turn on LCD
2.Press “up” &”down” together for more than 2 seconds in 3 seconds after LCD display – Then “72” will flash.
3.Press “down” or “up” to set any max speed. Press “SW” one time to save. Then “26” will flash. It’s tire size. Don’t set. Still press “SW” one time to save. Then “kmh / mph” will flash. Don’t set. Press “SW” one time to save.
4.At last, press “SW” more than 2 seconds, then will be back.

There is a Three button switch inside parcel.

** Black switch (be Left side / Middle – motor works forward. Be right side, motor works backward/reverse)
** Red switch (Be left side / regen off. Be right side / regen on)
** Green switch ( When motor is working, press this green switch one time. LCD is display C, motor will work as the same speed) – Re-press this green switch one time, or press brake lever, turn throttle to max, motor will stop.

Hub motor or controller short circuit fault

Posted by on April 4, 2025 Comments Off on Hub motor or controller short circuit fault

I purchased a 29 inch 1500 watt rear hub motor kit before you sold the kit with sine wave controllers 5 years ago. I love your hub motor. It’s very fast and powerful. I think your hub motors are the best in the world. I have recommended your bike motor to many of my friends. I
am going to buy a new 29 inch bike motor kit.

I am writing because I get a hub motor or controller short circuit fault message on the display when I use the walking feature. I hear a thumping noise when I use the throttle, but the motor doesn’t spin. Does this mean the problem is with my controller or with my motor?

Usually, this phenomenon may be caused by the following situations.

1. Caused by a short circuit between the positive and negative poles of the power supply. The positive pole of the power supply is connected to the negative pole, and the negative pole of the power supply is connected to the positive pole.

2. The voltage of the battery is too high, exceeding the maximum value of the controller capacitor, causing instantaneous breakdown of the capacitor.

Of course, it is also possible that the circuit board of the controller was not cleaned thoroughly, and the solder beads caused short circuits between electronic components.

The issue comes from hub motor controller.
If possible,open this controller and check if the capacitor has been burned out. It’s easy to open this controller box. Only use a screw driver to take off 4 screw nuts per side. Then can take the PCB out of controller.

Can re-test it as below:
Connect hub motor controller ‘s red and black power wires together. Discharge the electricity from the capacitor. Then re-connect them to battery power wires.

I want to purchase one of leaf hub motor kits

Posted by on April 2, 2025 Comments Off on I want to purchase one of leaf hub motor kits

I have done a lot of research and leaf motor and services keep coming up as a fine choice.

My original choice was the 3000 watt hub motor but I have already spent a lot of money on the electric bike and so that will have to come later but from what I have read this one may do just fine.

I currently run a 6T hub motor with a 48V 20A battery pack in a GT bike frame I build a few years ago and really like the way the hub motor runs but would like more speed so I ordered a new Raptor 76r frame and plan on using leaf motor in that setup so my questions are as follows:

The frame has 150mm dropouts in the rear.
From the previous build I already have a premium 48V 20A rated up to 50A output lithium battery pack that I paid 900.00 to have built so I will have to base the new hub motor and brushless controller around this for now.

AT first I was just going to get the 26 inch 1500 watt 4T leaf hub motor kit but then read it was better to have these in the 17” or 19” motor rim for this frame

Do you offer the hub motor with the 150mm axle?

I want this to run at close 40mph / 60kph the 4T should do that but I also would like the upgraded controller over the standard. What is the best motor controller you offer with the 1500 watt motor?

I also noticed you had a 2000 watt motor in the motorcycle section. Is this hub motor available for the bicycle kit and what are the specs on it?

What controller does the 2000 watt motor use?

I am going to buy at least 2 of these. One in the next week +a bare spare and another in a month or so and then probably 2 or 3 after that. I have several friends that want a bike like mine so after I get mine done will be building theirs as well.

At the least I will order the standard 1500 watt hub motor kit in either the 26 or 24 or 20 rim and then I will just pick up a spare bare hub motor and lace the rim myself.

Q: You said:”3. Default: 5T. But we can make 6T, 8T … (Please leave message when you order)”
I have not read about an odd number such as 5T. Is this correct that your default is 5T?
Also, Do you have a right half twist throttle available for this instead of the right full twist?

A: Generally 700c 48V 1500W hub motor,use 5T.
If you leave message: 5T when you order (or send an email to us after paid) – It must 5T.
Yes. We also have other throttle. Please click below site. All throttles are fit for this bike conversion kit LBCK700C481500RN.
