Look for an Electric motorcycle motor kit

Posted by on February 8, 2022 Comments Off on Look for an Electric motorcycle motor kit

I just bought a gas moped (49cc) and plan to convert it to electric with your electric motorcycle kit. It looks like I’ll need at least 1500W rear hub motor, although I’m willing to go higher if needed (2000W?). Someone on a forum indicated that you do custom windings and I should reach out to you, but I’m not an engineer and can only describe how I’ll use the moped – I can’t offer what specs are best, or if this is within what you can offer.

I would prefer a solid wheel (no spokes) but on your site those only go to 1000W?

The original moped rear wheel is 17″ with a M62 3-17 tire. I haven’t removed the tire to get the exact fork distance, but I think it is around 175mm

I don’t need a high top speed, 20 mph maximum and mostly I will be in the 0-10 mph range. However, it will be constantly going up and down hills, including several hundred feet of about 15 degree incline. So, I need good low-speed torque.

I weigh about 200 lbs, and the moped (and the tools I’ll be carrying) adds another 100-150 lbs.

This will never be used on public roadways, only on my farm. I live in the USA.

I haven’t started looking at controllers or batteries yet.  My first step is to identify the best hub motor option, then I can worry about the rest. 

I’d prefer a 17 inch casted electric motorcycle hub motor if I can get one with enough power / torque at low speed.

Bike Motor and Battery Wheel Hub

Posted by on February 7, 2022 Comments Off on Bike Motor and Battery Wheel Hub

As I called about,  was wondering about the electric front bicycle wheels you had. Can one buy either a bike motor or would buying an entire front wheel with a motor already included ? 
If I got a bike motor for the front wheel of a mountain bike, say as an example,  Model:HBL-16,  exalt how would this be inserted into the existing spokes of the center of the wheel ?   
Whether the entire motorized front wheel can be bought or just the front wheel hub motor, how do the controls with a front wheel differ from a back wheel motor ? 
How water proof are these motor hubs ?  How long does a motor of 36V/48V and 750W/1000W  they take to fully charge and how long would the charge last ? 
 
The options of Shipping seem fine, though I am not a whole-seller, so I assume I can buy just one or two items at a time. I also do not use paypal, what other methods of payment may I use ?  

Your E-bike company may just be what I’ve been looking for a while now, though I have a least another set of questions before I attempt to make a purchase to ship over. 
I’m still having some troubles determining on your website exactly the difference between which motor hubs are for the front vs the back wheels.    
I only want to get the front wheel set up at the moment, though ultimately the back wheel motor I’m guessing should have a little more power than the front wheel,
or should it be eventually an equally balanced between the front and the back wheel ?  (maybe I should go for a 24 to 36 volt in the front and a 36 to 48 reserved for the back.
 
You’re right when you point out that I should have the necessary kit accessories set-up to go with the front bike motor, such as a battery which I hope to mount somewhere
in-between the bike’s triangle bars, which I will also need a mount bracket for the battery I assume., along with a speed controller and If my existing gears won’t do the trick,
then maybe special gear shifts added to the package. I don’t know if I want get the entire front and back conversion kit at this time, unless it  would be a bit cheaper and easier
to buy the front and the back as a whole set with the accessories, as I can always leave the back wheel mechanism in my closet for a time and just install the front motor.
 
You say most of your motor hubs are fairly rain proof but not exactly mud puddle proof ?  Same I guess would go for the Battery cases.  
 
I will check things over again on your site along with the shipping arrangements, but I may still have to call you to confirm my slight back vs front wheel confusion. 
 
I may still buy both the front and back wheel hubs, along with whatever else is needed. As long as they could be put together separately, though that may require two separate 
batteries or is one battery good enough for both wheels ?  However, I was wondering just as a kick-start, you wouldn’t happen to have a front wheel-Hub with the battery included 
within the wheel motor case itself as part of a front wheel ?   (This isn’t what a Motor:brushless hub is, about is it, a battery contained within the wheel motor hub itself ? 

I have a 16 hub motor with leaf bike on the rim

Posted by on February 7, 2022 Comments Off on 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

Posted by on January 29, 2022 Comments Off on 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.

Answer 3:
We offer 36V/250W — 16″ 18″ 20″ 24″ 26″ 700c 28″ e bike kits.

electric bike battery can’t be charged

Posted by on January 29, 2022 Comments Off on electric bike battery can’t be charged

Question:Ordered 1 set of electric bike battery one year ago,last night charged it for the whole night,rode it this morning,but the hub motor stopped less than 1 mile.

I found the green led on my charger always be on while charging,it can’t turn to red.

Answer:There are two leds on charger.One is green led,the other is red.
When red led be on that means it’s charging.It’s okay.
When green led be on,there are three status:
1.Full charged;
2.Charger doesn’t connected to battery;
3.Can’t charge li battery

Everyone know the first and second status.But the third status isn’t easy to identify.Above question belong to the third status.

Now we talk about LiMn2O4 battery.
1.24V limn2o4 battery:
Fulled charged:29.4V;Dis-charged:22V
Should charge battery before it drops 22V.
If voltage is less than 22V,the charger can’t charge battery because of over discharged.
2.36V limn2o4 battery:
Fulled charged,42V; Dis-charged:34V
Should charge battery before it drops 34V.
If voltage is less than 34V,the charger can’t charge battery because of over discharged.
3.48V limn2o4 battery:
Fulled charged,54.6V; Dis-charged:46V
Should charge battery before it drops 46V.
If voltage is less than 46V,the charger can’t charge battery because of over discharged.

Why li battery will be over discharged?
1.24V motor controller can work at 21V±1V;the under voltage of 36V controller is 31.5V±1V and the under voltage of 48V controller is 42V.
2.Li battery has BMS.If the voltage of 24V,36V,48V li batteries less than 22V,34V,46V.BMS will stop charging and protect cells.

We suggest charge your electric bike battery per 20 miles.
Now our motor controller works with LCD,this lcd can display battery voltage directly so that you know when you should charge battery.

High power motors

Posted by on January 29, 2022 Comments Off on 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.

Our electric bike motor:
1.14″ 16″ 18″ 36V 750W & 48V 1000W front & rear casting hub motor;

Some noise from rim or hub

Posted by on January 27, 2022 Comments Off on Some noise from rim or hub

Q:After running for a couple of weeks.Sometime you can find there is some noise from bicycle rim while you are riding.

A:Now you should check spoke nipple.If can’t find 36 pcs nipple on spokes.There must be some nipples inside the rim,if not,maybe some aluminium impurity.

Solve:Disconnect your hub motor wheel from your e-bike,remove the tyre,you will find there is a red gasket round the rim,also take it off.Then make the valve hole down,shake rim,the impurity will be out of the rim.Re-install them.

Solve this noisy problem.

Advice: We suggest after running several days,had better to tight 36 pcs nipples.

Q:Can you help me?I am very disappointment.
I ordered a motor from the other supplier,the HBS36F — Front Motor.Sent several emails,haven’t gotten any reply in 2 weeks.

I have just tested it and it makes a noise once every turn and it gets stuck (or at least much more friction) at the same angle. It feels like it could be some magnetic effect but more likely it´s some mechanical contact that´s disturbing the rotation. Have you heard of this problem before or is the electric bike motor constructed to act like this? Could we do something to fix it, like open it up and remove whatever that´s making the noise?

A:The noise comes from some metal impurity on the magnet.

Solve: Disconnect hub and remove it

Instructions for 36V rear hub motor

Posted by on January 27, 2022 Comments Off on Instructions for 36V rear hub motor

Q:I am writing to see if you have any kind of instructions to install the hub motors and controllers I purchased from leafmotor.

I received two 36V hbl hub motors along with two lcc-001 controllers.
I did not receive any instructions as to how to install them.

The wires are labeled as follows:(heavy gauge wires)
Black has a dash – goes to the battery negative
Red is connected to a male connector with a smaller purple wire that says Power Switch and that goes to Battery positive.
The following I am not sure of:
Green says Mb
Blue says Mc
Yellow says Ma

The lighter gauge wires from the 12 pin connector are as follows:
Red goes to Power Switch terminal (mentioned above)
Black goes to the center of the 3 pin connector and to the 4 – 2 pin connectors
White goes the brake plug
Purple goes to the reverse plug
Green goes to the 3 pin connector
Brown goes to the horn plug
Smaller red goes to the 3 pin connector
Orange goes to the cruise connector

I do have a few questions about the power & horn switches and the speed controllers.

1. Can I use one switch for each of the functions below?
a) one switch to turn power on and off for both controllers?
can this be a simple on-off toggle type switch?
b) another switch to activate both horns?
can this one be a momentary push button switch?
c) and another switch to control the speed of both hub motor?
what type of switch is needed for this function?

2. How can we control wheel speed when turning as one wheel would need to spin slower than the other throughout the radius when making a left or right hand turn?

Note: I do not have handle bars on this vehicle. It is a four wheeler and it uses a rack and pinion steering system with a steering wheel. I would need to have switched that can be mounted on a flat surface instead of on handle bars.

some trouble with my electric bike

Posted by on January 26, 2022 Comments Off on some trouble with my electric bike

Q:I have some trouble with my electric bike again. This time the battery is okay, but hub motor is totally “dead”. The bike just stopped when I was driving. Do you have any suggestion about what to do? Is there any fuses or something else to check? All the wires are okay. Can you help me?
A:If you make sure the wires are okay. I think the problem possible comes from battery.
Case maybe when you measure the voltage of your battery,it is standard voltage,but when you need to run your wheel,the voltage will jump down less than the voltage which can drive the controller work.
You need to measure the voltage of your battery when your bike works. Not always need the motor works,just need to connect all wires and push your throttle.
See the voltage change from your battery.
Q:nothing is happening with the battery when I turn on the engine. The voltage is standing on 41 volt all the time, nothing is happening. I have opened the controller and checked the led lamps and the light is on on led 1 and in led 2 is the light blinking 6 times and then a short stop and then it´s blinking 6 times again.
So I wonder that the problem is, is it the wheel or the controller or the throttle, is there a way to test which part it is or do you have a clue? Is there any part that I need to replace with a new?
A:Could you tell me what kind of controller you use?
The problem may come from the controller.
1.Throttle
red wire and black wire: 5V
2.Hall sensor(five wires)
red wire and black wire:5V
Q:I have been doing these tests and the results is:
on number 1 (trottle)= 4.5V
and number 2 (hall sensor) = 1.2V
so it´s not the same as you have.. the battery is 41V
hoping that you can figure something out from this!
Measure the controller:
1.Disconnect five hall sensor wires from the motor
2.Measure the hall sensor(red and black) wires from controller
Hall sensor from controller(five wires)
red wire and black wire:5,13V When unplugged and 1,32V when inplugged

black wire and green wire: 5,13M Ohm
black wire and blue wire:5,12M Ohm
black wire and yellow wire:5,09M Ohm

So this means that hall sensors are broken?
What shall we do?
Is it possible to repair or change these sensors?
