hub motor selection and rim width.

Posted by on December 29, 2021 Comments Off on hub motor selection and rim width.

I am looking to build an e-bike, starting with the Mongoose Dolomite. 5000W is probably too much, I see you offer 1500W hub motor kits, but I did not see any information about 4inch wheels for the fat tire bikes.
Do you have a 26 inch bike motor kit for the 26 inch fat tire bikes, rear drive, 1500W or more?
With a 9 speed cassette is there enough room for the hub motor in a 135mm drop out ?
I see now that my Shimano 9 speed rear cassette should be the same width as a Shimano 7 speed. It is the spacing of each gear that is different. However, if I am to purchase your kit, I would need you to supply the 9 speed freewheel because I assume your hub motors use freewheels and not cassettes. Right now my bike is a cassette.

Unless it is possible to supply this bike motor in the kit instead:

I should be able to mount my cassette to this motor. Can we do that instead?

This is no longer for fat tire bike so please ignore the first email about the fat tire kit.

It is for a regular mountain bike so no need to worry about 3 or 4″ tires. I have regular mountain bike tires, 26 x 2″ right now. Once I do the electric bike conversion kit, I may switch to more narrow road tires like 1.5″ or 1.75″ so the regular double wall mountain bike rim is fine.

So I made a new order with the individual parts and I excluded the brakes because I do not need them. However, it came out to be a little more expensive than selecting the kit but, I would like a double walled 26″ rim added to the hub motor please.

Just wondering what type of connectors come on the motor controller? I am ordering my battery and need to know what kind of connectors it has. Do you have any pictures or description?

Interested In Buy This Hub Motor

Posted by on December 29, 2021 Comments Off on Interested In Buy This Hub Motor

Q: I am very happy in viewing your electric bike rear direct drive with
26 inch hub motor wheel item ID # LBM26481500RN. My e-bike setup is 60 volts. Do you
manufacture 26×2.0 inch wheel with 60 volts 1500W rear direct drive
hub motors?
Secondly, also can you fit the bike motor in a fully BLACK rim without any
silver around the rim so it can match with my front wheel because I
use hydraulic disc brakes?
If there is anything that you need to ask me that I am missing, please
feel free to ask, that the purchase moves smoothly and correctly.

A: This 26 inch 48V 1500W rear hub motor wheel can work at 60V.Also,we can spoke this hub motor with all black color rim.

Q: Just a few more questions before I buy, because everything needs to be correct.
Can this bike motor fit any size frame bike?
Is it suitable for regenerative braking?
Does it have three phase hall sensors?
Can it fit 8 gear cogs? Which I am using at the moment with my old motor.
Please tell me the total length of the motor axle from end to end
because I’m using a rear rack ?

A: This 26 inch bike motor is fit for 135mm rear dropout. If your motor controller with regenerative braking function, will have it. It’s three phase with three hall sensors. One cable with 9 wires: heavy yellow, heavy blue, heavy green wires are motor phase wires. Thin red +5V, thin black / GND. Thin yellow, blue & green three wires are connected to three hall sensor.
It can fit for max 7 speed for 135mm dropout. If your frame can be larger, about 140mm,install 8 speed on this rear hub motor is no problem.
Total length of this shaft is 210mm.

question about one of your front hub motor for my electric bike

Posted by on December 29, 2021 Comments Off on question about one of your front hub motor for my electric bike

Q: I am interested in the 20 inch 48V 1000W hub motor electric bike kit – front wheel but I need to know what the front dropout size this hub motor wheel will fit. I have a small folding bike that has a front dropout of 74mm and need a 20 inch hub motorized wheel that can fit it. Any help you can give me would be great.

A: One of our 20 inch 48v 1000w hub motor (all black color bike motor) is fit for the spacing of 100mm front dropout.
The other 20 inch electric bike motor 48v 1000w (black color with silver motor) is fit for the spacing of 90mm front dropout.

Q: Do you have anything that can fit a 74-80mm dropout? It does not have to be 1000w. I am now looking for a 36v 250w electric hub motor kit?

A: Generally nearly all standard front fork is 100mm dropout. So all of our front electric hub motors are fit for 90-100mm.

Does your front fork is 80mm dropout?
Sometimes,when your wheel is on the bike,if you measure it the dropout may 80mm, because of two side screw nuts are be tighten.If you remove this front wheel from front fork,the dropout may be bigger,actual it also standard 100mm dropout.

Could you take a picture with your bike?

missing thread of hub motor shaft

Posted by on December 29, 2021 Comments Off on missing thread of hub motor shaft

It took a little work since spacing was tight, but I get the hub motor wheel inside of my forks. When I went to put the nuts on the axle, I saw that the bolt on the wired side is cracked. It is missing almost all of its thread which means I cannot but the nut on to hold the wheel in place. Essentially, I cannot use it at all. Please see the picture of the cracked bolt.

I was wondering if you know how I am able to repair this hub motor ‘s shaft or if I can somehow get some help on this? I spent a lot to get it all here and it is a little upsetting that a small chip is preventing me from using it at all. I’m not asking for a whole new electric hub motor wheel to be sent, just hoping I can get this bike conversion kit up and hub motor running. Please advise.

If possible, add some washers,then can solve it.

Do it as below:
Disconnect that white big plug,then can take off screw nut and add some washers into.
*. Look for a pin
*. There are five wires in this white big plug
*. Press each wire’ s pin, then the pin will out of white big plug.

I had thought I got bike conversion kit to work but there just is not enough room to to secure the nut properly. Please let me know what will be the best way to have this resolved. Sorry for the inconvenience on this.

Add washer or torque arm or lock washer.

Question about 26 inch 36v 750w rear hub motor – bike conversion kit

Posted by on December 29, 2021 Comments Off on Question about 26 inch 36v 750w rear hub motor – bike conversion kit

Question about 26 inch 36v 750w rear hub motor bike conversion kit
1. Is the 750 watt hub motor good bike conversion kit for hill climbing? If not what would you recommend?
2. Is the electric bike motor controller current limit set to keep from burning out the hub motor when loaded?
3. I see the hub motor spec sheet is quite old 2013. Is there an up to date one?
4. What is the full old current of the motor at rated N-M load or torque?
5. Any service places for your parts in the US?
6. What size electric bike battery is recommended for your motor and controller? 36v 15ah?

1.We can make hub motor with low speed,will good for hill up.
2.Hub motor controller max 26A,so that electric bike motor max 26A
3,4.Only tell us max speed,we can customize motor…lower speed,stronger torque
5.no service place now
6.recommend 36v 15ah or more ah

Yes, I would like a lower rpm hub motor for hill up if the cost of the bike conversion kit does not change. Maybe 25 mile hour max speed flat ground or about 311 RPM. What would you recommend? What do you have that is close to that?
I need to order shortly to not miss the special on shipping that is coming to an end on Dec 28th.

Yes.We have.
When you order,only leave message: 25mph or about 311 RPM.
Then we can make this hub motor as your message.

Would it be possible to get the hub motor data for this different motor like you have on your other motors? I really like that data as I can see what the electric bike motor is capable of.

I don’t understand this phrase “Mechanical brake: Default Disk or V (If need to install drum brake,please tell us in advance)

I have not heard of drum brakes on a bicycle. I don’t have disk brakes right now but would prefer the motor be capable of adding that even though I have V brakes on the bike right now. So what should I ask for?

I forgot to add that I don’t want a geared 26 inch electric bike motor wheel. the gears are plastic and won’t last long on the hills. I hope that does not cause a problem.

Headlight 1000w rear electric bike kit

Posted by on December 29, 2021 Comments Off on Headlight 1000w rear electric bike kit

Q: I bought the 26 inch rear 1000 watt electric bike kit how do you wire the headlights to it I see a headlight display on the LCD screen and a switch for the headlights but no wiring diagram for that.

A: How to use three button switch?
1.We cut off that blue wire.It’s for reverse. If reconnect this blue wire. (Reverse is dangerous for e-bike. So we cut off blue wire)

This yellow button be left / middle,hub motor works forward. Be right side,motor works bacwkard / reverse…

2.Green button is used to control cruise, while hub 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 regeon.

Q: I appreciate your help in this matter is there anyway I can get a copy of the proper settings for the P and C settings on the LCD for the 48 volt rear hub motor kit.

I understand that but when I was trying to set. I’m afraid I opened the P settings and then went into the P settings before I realize what was going on I’m scared I might have changed something is there any way to get a copy of the P and C settings or will a factory reset work if there is any possible way to get a copy of what the p and c settings are supposed to be so I can double-check them it would be greatly appreciated.

A: P1 = 46
P2 = 0
P3 = 1
P4 = 0
P5 = 15

Q: My battery management chip on my battery was not plugged in all the way so I think that may have been the problem I’m charging it all the way up now I appreciate it though thank you very much just out of curiosity is there anyway you can get me the C settings for that 1000W rear hub motor kit .

Question about 16 inch electric hub motor kit

Posted by on December 29, 2021 Comments Off on Question about 16 inch electric hub motor kit

Q:I thank you very much for UPS tracking number. The parcel should be delivered to me these days. Perfect.

Anyhow – I have one question regarding capable Li-Ion-battery pack for “16 inch, 36 V, 250 W front hub motor – electric bike kit, Item No. LBCK1636250F” which you shipped to me.
I have already one Li Ion-Battery pack; 36 V, 504 W, 14 Ah. Is that Li-Ion-Battery pack suitable for using with E-Motor I ordered from you?

A: Just connect your battery to our controller, it works.

Q: You shipped to me in Oct. 2018 “16 inch, 36 V, 250 W front hub motor-electric bike kit, Item No. LBCK1636250F”.
Today first, after buy of kick bike scooter (not pedelec), I install complete kit on my kick bike scooter and it works not. Display works normally (battery indicator full) but it is no E-Motor Watt-indication and no E-Motor reaction after switch on gas-accelerator (speed adjustment not 0 but 1 till 5).
After check of all delivered Parts from your Company and received Datasheet, I discovered some discrepancies:

1. Which voltage has E-Hub Motor, 36 V or 24 V ? (See attachment Page 2/6 and Page 3/6 as well as Page 4/6 with Photo1)
Remark: Delivered E-Motor has no technical dates described on the motor alone.
2. “Cruise button (red/green as shown on the Page 4/6 its other one; See Photo 2)
3. Delivered controller has another dimension as shown on page 4/6; See Photo 3)
4. Which are correct installations codes to be installed for P1 till P5 and C1 till C14?

Awaiting your response asap of the above questions and your statement above delivered kit. Thanks in advance.

A: controller works with 36v battery (min 30v to max 42v)

Please check if there is “-O-“ on the middle/ top of screen.. If have, the system is braking… please disconnect brake lever’s plug or make brake lever’s ring be back. Then motor works.

Please check the blue wire of three button switch if cut off. If cut off blue wire, that’s okay.. If no blue wire cut off, must push the yellow button the other side, motor works. (The yellow button on your picture that works backward status. This motor Not support backward status. So not work)

I have trouble keeping the wheel true and recently have a lot of broken spokes and a cracked rim. It is also hard to pedal because of motor drag and I want to be able to ride it without the power on or if the battery went flat. I can’t do that now. I am interested to know a few things 1. What is the weight of the front wheel hub motor? 2. You can see my bike has the front wheel a much further distance from the handlebars.Can you supply this hub motor kit with longer wires - or extension wires with appropriate connectors - so the wires can be routed under the cargo area and up to handlebars? 3. Is the voltage programmable with your system? (My existing motor can be)(I have a big battery pack) 4. I have hydraulic disc brakes on my bike and want to be sure this is compatible with disc rotors A: 1. The net weight of this motor is 7.25kg 2. Yes. When you order on our site,just leave message: cable length, then we can make. 3. The voltage isn’t programmable. This 48v controller works with 48v or 52v battery. (from min 40v to max 60v) 4. There are six screw on left cover for install disk. The dia. is 44mm (between two screw holes)

leaf bike 26 inch 48V 1500W rear hub motor wheel kit

Posted by on December 29, 2021 Comments Off on leaf bike 26 inch 48V 1500W rear hub motor wheel kit

Q: I am interested to buy a complete Rear 1500w hub motor wheel ( the latest model with upgraded phase wires, 0.35mm lamination etc).
The model model I think is LBM26481500RN and I would like to know the following before if buy:
– the no load rpm for 4T, 5T and 6T motor at 48v
– and the top speeds under load for 26 inch wheel.
I am looking to have a maximum 55 – 60kph (not less than 55 ) top speed under load but a bit more torque for off road riding.
Also for a electric bike motor with disc brake mount, cassette, temperature sensor and a rim that fits a 2.5 tire is the same price?

A: If not load, 4T 1500w 26 inch hub motor is about 72kmh (work at 48v)
If not load, 26 inch 1500w 5T is about 60kmh (work at 48v)
We can make cassette case motor with 2mm phase wire. But we still recommend standard version with thread screw with 2.5mm phase wire.
Also,standard version is easy to install than cassette case..
* With disc brake mount, cassette,temp,rim fit for 2.5 tire – The same price.
We recommend: with disc brake, standard version (No cassette version),temp,rim fit for 2.5 tire.

Q: can you please send me a more precise data (numbers) about the rpm @ 48V for each available wingdings available, like a performance table or similar?
I found on internet different available information for this motor, but their are not consistent, there are also the forums..and each data is different.
I was hopping that you can provide me more figures..
And also,I don’t understand why for the cassette hub the phase wires are 2mm while there are existing on the opposite side ?

A:Thank you so much for the clear explanations, I understood very well now what are the draw backs for each design.
Also, I was looking over the performance datasheet and I suppose that those parameters are for the 4 turn winding I suppose right?
So for the 5T the maximum rpm with be lower and torque a bit higher. Also the max efficiency point will be at a lower rpm.
Good, so if I want to place an order for a 5T 1500W 26 inch Rear hub motor kit wheel with the following requirements:
disc mount
threaded sprocket
temp sensor
135 mm drop out
26 inch Rim for 2.5 tire (23-25 mm wide rim)
12 gauge spokes

A: Yes. That 4 turn winding.
If 5T, the max rpm with be lower and torque a bit higher.
26 inch wheel, we recommend 5T
Standard rear 1500w 5T with the following requirements
* can install disk the left side of motor
* can install threaded sprocket on the right side of motor
* with temp
* fit for 135mm dropout
* We have 26 inch out.size 25mm or out.size 32mm wide rim (Our 32mm rim is fit for 26 inch)
Please click below sites.
I think 26 inch all black color rim is fit for your 2.5 tire.
