I’m interested in your 18 inch hub motor electric bike conversion kit I was curious is this a right hand drive or left hand drive ? Does this come with a sprocket, and if so how
Many teeth does it have ? Is this strictly pedal assist or will the motor engage while pedals are at a stand still?
Do you have a 1000watt hub motor for the drum brake wheel?
Do you make 16inch electric front wheels for surrey bikes ? The axles seems slightly different then your standard bicycle front wheel
Do you have a diagram as to how the drum brake connects to the wheel ?
I see that’s a separate drum break to purchase. How does the 1000watt wheel attach the drum break? Is there a mounting system on the wheel ?
The actual drum break 1000watt wheel comes with everything needed correct ?
I would rather purchase from you if possible since our communication has been the best. Can you work with me on the price of the wheel ?
Are the drum break to the wheel universal? May I ask why the drum brake isn’t included with the wheel?
What is the return policy in case I have issues with it fitting my bike or performing ?
I am now in the process of ordering the electric wheel kit for our surrey bike. Before ordering I was curious do you have the updated lcd screen for this model ?
It would be the same wheel, the rear 18inch wheel conversion with drum break.
Is there any documents showing the way the lcd screens look? Is one better then the other ?
I can choose a colored lcd screen for the controller as well correct?
Before I make a purchase I was going to ask do you offer a thumb driven accelerator switch instead of the throttle handle like a dirt bike.
Can you send me a picture of what it looks like please.
I was asking if I could see a picture of the thumb throttle as well
One more question about your thumb throttle. Do you have a thumb throttle that does not have the handle attached ? I’m trying to secure the thumb throttle to a sealed bar so I need it to open and latch over the bar to secure it instead of slipping over the end of a bar like a bike handle grip. If this makes sense?
Sounds good. If I were to want this one how would I express in my order I would
Prefer this thumb throttle ?

18 inch 48V 52V 1000W rear hub motor – electric bike kit
Question on wiring- 1500w rear hub motor kit
I have installed my hub motor kit on my bike and think IT IS GREAT!!!!
I have a question about a wire from the “cruise control-regenerative brake” controller on the handle bar.
The connection to the control unit had 4 wires one of which……the blue wire…was cut.
I assumed that it needed to be fixed the two blue wires together.
I bought two hub motor kits and we have just finished installing the kit on my friends bike and this blue wire is also not connected…..so I am wondering if it is supposed to be disconnected……should I solder this blue wire of cut the blue wire on my bike …..
Again….I think your hub motor kits are great! I have referred my friends to your site and I hope you receive some orders from them.
How to use three button switch?
1.We cut off that blue or yellow wire.It’s for reverse/backward.This function is very dangerous for e-bike. If for e-tricycle,hope this reverse function,just re-connect this yellow wire.
(We cut off yellow wire.. so no reverse/backwards function for e-bike. If install motor on tricycle, also need this reverse function,please re-connect this yellow wire. Reverse works)
This yellow or black button be left / middle,motor works forward. Be right side,motor works backwards / reverse… (Cut off blue wire,No reverse function)
How to set max speed?
If you feel motor is too fast,please set it to be low speed.
* Press “sw/middle button” from LCD more than 2 seconds,then LCD will display.
* Press “up & down button” together more than 2 seconds until 72 is flashing ( 72 is kmh, if you hope works 20mph / 32kmh, press “down” to be 32)
* Press “sw/middle” button one time to save,then 20 is flashing.. (20 is wheel size. Don’t set)
* Press “sw/middle” button one time to save,then kmh or mph is flashing..
* Press “sw/middle” button one time to save,then press “sw/middle” button more than 2 seconds until be back.
Turn throttle,motor will work max speed as your setting.
—————
There is a “ 5 or 4 or 3 or 2 or 1 or 0” on the Left side of LCD.
* Be “0” – throttle & pedal assist NOT work.
* Be “1” – throttle works (If install pedal assist, pedal about 3 circles,then can drive motor to work)
* Be “2” – throttle works (If install pedal assist, pedal about 2.5 circles,then can drive motor to work)
* Be “3” – throttle works (If install pedal assist, pedal about 2 circles,then can drive motor to work)
* Be “4” – throttle works (If install pedal assist, pedal about 1.5 circles,then can drive motor to work)
* Be “5” – throttle works (If install pedal assist, pedal about 1 circles,then can drive motor to work)
If NOT install that pedal assist,ONLY use throttle to drive motor. But Should be 1 or 2 or 3 or 4 or 5.(Be 0,turn off throttle)

2.Green button is used to control cruise, while motor is running,also over some speed,example: over 1/3 max speed,at this time,press green button one time,then loose throttle,LCD display “C”,motor will works the same speed. Re-press this green button one time or press brake lever or turn throttle to max,motor will stop
3.Red button be up,regen on. Be down,regen off. This regen is not strong.Only while braking with a little regen.
1.Be careful:
Heavy Red Wire from controller should be connected to → Red Wire + (48V or 52V battery positive)
Heavy Black Wire should be connected to → Black wire – (48V or 52V battery negative)
Power on battery. Press “sw” middle button more than 2 seconds until LCD be ON. Turn throttle,motor will work.
If Not work,please check below:
1. if LCD display “-O-“, the system is braking,cut off motor power.. please make brake levers’ metal ring be back or disconnect brake lever’s plug, then “-O-“ off, turn throttle,motor works.
2. if no “-O-“, still not work,please check three pair of heavy phase yellow,blue,green wires if connected well.
1500W Leaf Motor with 20″ x 4″ wide “Fat Bike” wheel
Q:Do you sale 1500w or higher hub motor laced into wheel that is 20” diameter by 4” wide for fat tire bike? If so, what are the dropout width options for axle? Can axle dropout width be 150mm wide or even wider? I have a bike frame with 170mm dropout width. I can use torque arms and spacers to fill some of this space, but not too much.
If available please quote price for:
~1500w newest model hub motor with 20” diameter x 4” width wheel (pre-laced service)
~Need motor/wheel laced with 1 cross pattern. Radial lacing is acceptable but not preferred. Black spokes preferred.

If 27.5” rim is smaller than 700c and larger than 26 inch rim?
* If you need to install your 7-speed cassette sprocket. Please Note when you order.
Q: I want to use the newest 1500w hub motor in this bike:
If you press the green + (View all components) on the page you can see that it has 27.5 INCH x 50mm, tubeless ready rims and 142x12mm (Ai offset lacing) rear drop out.
So I’m wondering if you can deliver the hub motor with a rim that’s the same dimensions as the original rim?
A: We have some sample of 27.5 inch rim in stock. Looks the same to the one on your site.
We only ship two 27.5 inch hub motor kits to USA one time two month ago.(ONLY one customer need this 27.5 inch by now)
This 27.5 rim is smaller than 700c and larger than 26 inch.
Q: This sounds good. Thank you for even taking pictures.
How wide is the 27.5″ rim you have? (How many millimeters)
I have a 16 hub motor with leaf bike on the rim
I need to know what voltage is used by the 16 inch hub motor. When it was running on a trike that I no longer have, I think it was a 24v hub motor.
Can you confirm that it is a 24v hub motor or is there someway to determine what the voltage and wattage is?
If so, would you be able to sell me the appropriate controller for that hub motor?
MY SECOND MESSAGE slightly expanded:
I need to know what voltage is used by my 16″ hub motor.
Is there someway to determine what the voltage and wattage is? Also, is
that hub motor brushless and gearless?
Given that it is a Leafbike.com/Leafmotor.com hub motor, would you be
able to sell me the appropriate controller for that hub motor?
On your
16 inch 48V / 52V 1000W front scooter motor kit Item ID #LBCK16481000FNL page you show a controller for the 16 inch hub motor. What would be the
cost of the controller – the controller only? I do not want or need the
other parts.
Please tell me how to pay using VISA or PayPal. Kindly send me an invoice for 24V 250W electric bike motor controller, and I will pay with a VISA debit card.
I thought that I ordered a 24v controller for $112.00 which included a faster delivery, BUT when I tried to find the order on “My Account” I could not find it. Your “Live Chat” link would not work. If it had, I would have used it. Please advise regarding my order for the 24v controller.
Will you kindly tell me what color wires are wired to the thumb drive?
I am using a 24v front hub motor
I am so pleased you answered so promptly. However, I am having trouble understanding your description. Would it be possible to send my a drawing or diagram showing all the wires from the controller and where they are going?
All I need is the color of the wires going to the 16″ front hub motor, the battery, and most important, to the thumb throttle.
I am attaching and embedding modified photo from your website. I you could simply label the wire colors and return to me?
help me purchase 250w electric bike kit
Q:
I want to purchase 1 set of 250w electric bike kit,but found there are two type 250w hub motors showed on leafmotor’s internet shop.
One motor is 250w gearless hub motor,the other is 250w geared hub motor.
Help…What’s the difference between them?Which e-bike kit should I order?
Answer 1:
Order 250w geared hub motor,it’s more popular these days.
Answer 2:
250w gearless and geared hub motors are the same brushless motors.They are both made up of rotor winding,halls sensor, magnet, hub…
The difference between them is with gears / without gears.
250W geared hub motor is a little more powerful than gearless hub motor,but there is some noise from gears.

High power motors
I have tested the new wheels and the performance from them is perfect.
I have tried them in my bike that has the 24″ 48v1000w rear wheel that I bought from leafmotor in July 2010. This bike has 48v Lifepo4 battery and max speed is 36km/h with the July 2010 motor.
When I put the new 26″ 48v1000w wheel in this bike max speed is 50 km/h.
Then I tried the 26″ wheel in another bike also with another 48v Lifepo4 battery and the performance is also good.
I am interested to find the answer. I dis-assembled the new 26″ hub and the old July 2010 24″ hub and swapped the axle and windings from each motor, re-assembled them and tested again. The 26″ wheel now has 39km/h max speed and the old 24″ is 46km/h.
This tells us that the axle windings in each of the new wheels have much higher power capability than the older wheel.
Actually old hub motor and new hub are the same cost.
Everything is no changed,the same hub,the same rotor,the same magnet,except coil wires.
Change the gauge of the coil wires and/or the turns number of the coils can adjust motor speed,power etc.
Old hub motor is standard motor,it’s fit for US transportation law.26″ 36V 750W, the speed is 20 miles/hour.
If need extra speed,power etc..We can customize as your need.
I am also satisfactory with my bicycle.
18″ 48V 1000W hub motor speed:17 miles/hour
High power performance motor doesn’t depend on speed or power,but customers’ need,law allowed.
My 48V 15-MOS-FET brushless controller drive 700c 48V 1000W electric bike motor,has enough power to climb hill.
This is a reliable hub motor,never meet any problem in 1 year.
I ordered the same motor(hbl 36V 750W hub motor) last month and repeat testing it,perfect.
Not surprising.This electric motor is ripe product and used for e-bikes widely in China.Anywhere you can find this kind of hub motor in China.
You did make a good choice and ordered ripe motor.It’s better than internal control motor.That kind the controller is built inside the motor,because of high temp,easy to break controller.If the internal controller is broken,all system is dead,should replace controller and motor together.
After repaired this hub motor by myself as instructions shown on this forum.I am much better to like this motor,like leafmotor’s forum.
Received my 700c 48V 1000W electric bike kit two weeks ago and took 1 day to done installation.Ride it per day,be satisfying with motor powerful
This is brushless gearless high speed motor, compare to brushless geared motor.The second one has more powerful,but with a little gear noise.Now 750w and 1000w brushless geared hub motors can’t find in market.Most of geared motors are 250w.
We always think faster,better.But because of local law for ebike so that we can’t ride high power motor bike.
I received 36V 750W hub motor,then make a label ” 36V 500W” on it.
From you test,you think faster speed motor is more powerful,actually you are wrong.
Estimate motor performance:faster speed,less powerful,slower,more powerful.
About motor speed,power,I think leafmotor can customize it according as customers’ actual need.
electric bike motor
Hub motor,bldc motor,brushless motor,gasoline motor..Any kind of motor,used for electric bike,we call bike motor.
In North America and Europe,gasoline motor is still used for electric bike.Picture enclosed.It can’t received by most of people.
Electric gasoline motor bike,call it an electric bike?But it makes pollution.Call it motorcycle?But it more dangerous than motorcycle, they both have high speed.But the tyre of gasoline motor bike is the same to common electric bike.
Be tired for one week work,please be far from pollution – choose electric motor bike.

1.1 pcs of open-end wrench
2.1 pcs of phillips screwdriver
3.1 pcs of voltmeter
4.some zip-ties
How to install electric bike kit?
1.Make your bike upside down;
2.Use open-end wrench to loose both nuts and remove the front or rear wheel;
3.Find out the direction of motor runs;
4.Fix motorized wheel on your bike;
5.Use open-end wrench to tight both nuts;
6.Connect wires;
7.Make your wheel in the air,power on battery and test;
8.If it can’ work.Please use volt-meter to measure.
Electric bike kit does not work
Q:Received electric bike kit and assembled it according to the instructions,but nothing happens as turn the key and press the throttle. No sound, no movement. Every cable is connected as it should be. Tested the battery with a multimeter,it’s okay.
A:If the battery is no problem.Please test it as below:
1.Disconnect all external wires from brushless controller,except battery power wires and motor wires(blue,yellow and green three thick wires) and hall sensor wires(red,black,blue,yellow and green five thin wires);
2.Make your hub motor wheel in the air;
3.Find a three-pin throttle connector from motor controller,there are red,black and green three wires.Use a wire to jump red and green wires.
If your electric motor and controller are okay,it can run as the fastest speed suddenly.
If not,use your hand to turn your motor,be careful.Motor may run.
If work,problem may come from throttle wire connecting.
Solve:Check throttle connector and wire connecting.
Q:If still can’t work.
A:Should use voltmeter to test motor hall sensor(five wires):
1.The voltage of red and black wires is approximate 4.5V
2.The voltage of blue and black wires is approximate 4.5V or 0V(use hand to turn motor,it will change from 4.5V-0V)
3.The voltage of yellow and black wires is approximate 0V or 4.5V(use hand to turn motor,it will change from 0V-4.5V)
4.The voltage of green and black wires is approximate 4.5V or 0V(use hand to turn motor,it will change from 4.5V-0V)
If can’t get voltage from these wires,controller may broken or motor hall sensor is broken.
Received DIY kit does not work
I received your DIY electric bike kit about three weeks ago. 750W 36V with brushless controller. I have assembled it according to the instructions on your site, but one issue have arisen.Nothing happens as I turn the key and press the throttle. No sound, no movement. Every cable is connected as it should be. I’ve tested the battery with a multimeter,and the output is 36V, so there is nothing wrong there. I also tried connecting just the battery and the controller with no results.
I have tested the connection to the controller from the battery, and the multimeter reads 36V. The cables have been checked for bad connections,so I would think that the controller is faulty.
Answer 1:
The same problem to mine.At last I solve it.The problem comes from the wrong connecting.
Answer 2:
Remove all wires,except throttle and power wires.Twist your throttle,if still not run,please check the voltage from throttle.
The voltage of green and black wires is about 2.3V;
The voltage of red and black wires is about 4.5V.
If no any voltage from this throttle,check battery.If do have voltage input the controller,but no output from throttle.This controller may broken.Re-check wire connecting whether handle brake is hold off.
Answer 3:
Yeah,do it as Joe Horn said.
BTW,if your e bike kit is brushed,not brushless.
It’s easy.Connect two wires from your motor to the battery directly,the motor will run as the fastest speed at once.
Answer 4:
If the battery is no problem.Please test it as below:
1.Disconnect all external wires from brushless controller,except battery power wires and motor wires(blue,yellow and green three thick wires) and hall sensor wires(red,black,blue,yellow and green five thin wires);
2.Make your hub motor wheel in the air;
3.Find a three-pin throttle connector from motor controller,there are red,black and green three wires.Use a wire to jump red and green wires.
If your electric motor and controller are okay,it can run as the fastest speed suddenly.
If not,use your hand to turn your motor,be careful.Motor may run.
If work,problem may come from throttle wire connecting.
If still can’t work.Should use voltmeter to test motor hall sensor(five wires):
1.The voltage of red and black wires is approximate 4.5V
2.The voltage of blue and black wires is approximate 4.5V or 0V(use hand to turn motor,it will change from 4.5V-0V)
3.The voltage of yellow and black wires is approximate 0V or 4.5V(use hand to turn motor,it will change from 0V-4.5V)
4.The voltage of green and black wires is approximate 4.5V or 0V(use hand to turn motor,it will change from 4.5V-0V)
If can’t get voltage from these wires,controller may broken or motor hall sensor is broken.
Answer 5:
Re-check wire connecting and connectors,most of problems come from wrong wire connecting and loose connectors.
One in a thousand products’ fault.Any goods should test more than 2 times before we received.
Answer 6:
Thanks,all.I found the problem.The three pin male and female connectors can’t connect well.Re-made these two connectors,motor worked well without any noise.Perfect.
Answer 7:
Before ride your bike on road,had better to fix these connectors firm,if not,sometimes your e-bike will stop sudden when everything works well.
Answer 8:
I met this problem before,bike conversion kit can’t work,but shook cable,the system run as the fast speed.
Answer 9:
I re-made all connectors since received my first e bike kit.And connected all wires as leafmotor instruction,no any installation trouble.
