I have electric bike assistance that I myself mount, the hub motor wheel has a power of 1000 W and a lithium battery of 13 Ah.For almost 7 months that I use everything was going great and for a moment..I have a default code 01 that appears … and it feels like a strong push in power and a total stop with this error code 01, but it happens very occasionally, we will say that its the 3rd third time already.Looking at the leaflet this code indicates accelerator fault.I reconnected the various connections.Cs pedal sensor, hall, engine power, display etc everything seems normal. Anyone can help me solve this problem, thank you in advance Learn more at..

I’m interesting your product of New 26 inch 48V 1000W electric bike kit (Item ID #LBCK26481000FN), and having some question as below.
1. Does the kit already include regen function?
2. Is it possible to have a demonstration YouTube vedeo to show me the E-ABS regen feature?
3. Do you have magnet switch instead of Item ID #LBP002BL braking lever, because my current braking lever is an All in one type (braking lever and Shimano in one)?
4. As everyone knows the transportation cost is very high, if I can arrange the rim by myself from USA, can I replace order as following to reduce some transportation cost?
I want to make sure everything is the same as #LBCK26481000FN besides 26×1.95 inch rim. (The hub motor controller, LCD display, braking lever, three button switch, throttle etc…)
1. I always ride a route which include a lot of up and down hills, the longest one is a continuity down hill for 2 km.
it’s a 7% downhill, if you don’t use brake to reduce speed, the bike speed will be up over 45km/hr, so I always
use brake to control speed within a safety area( within 30km/hr), but after through the downhill, the rim become
very hot, it very bad situation.
That’s one of many reasons that I want to put a E-BIKE with regen braking function in my Bike.
According my description as above, is your e-bike kit suitable in this case?
4. Is the attached photo new version or old?
Do you mean that if I place order with #LBCK26481000FN kit set will get new version of LCD display?
If place order with LBC481000L 48V 1000W bike motor controller will get old version of LCD display?
When I downhill, if I release throttle and turn on the E-ABS by switch, but I don’t push the brake lever to make mechanical brake working. will bike glide freely and very fast? is the controller charging battery at this moment?
Normally when E-ABS turn on, the speed should become lower as below, is it right?
When a very long distance downhill (the same gradient),
if freely glide down (without throttle, mechanical brake, E-ABS), the invariable maximum speed is 35km/hr
when turn on E-ABS only, the invariable maximum speed should be lower than 35 km/hr, such as 25~30km/hr

on March 13, 2025Comments Off on looking an electric bike controller for 48V 1000W hub motor
I am using a brushless and gearless DC hub motor that is 48V 1000W. I am looking for a suitable bike motor controller for my project.
I want to implement regen braking, cruise, reverse, setting a speed limit etc.
Will this 48V 500W controller works for this 1000W motor?
I am quite hesitant to choose the 48V 1000W brushless motor controller displayed in the web here as I am afraid that the high power may drain too much power from the battery.
I am using a 48V 10Ah battery. It should be sufficient to power the 1000W BLDC hub motor but to power both the motor and controller, it may overstrain the battery.
Can you confirm that your brushless motor controller can set max speed limit, regen brake, reverse and cruise control?
Basically, I just need to buy the three button switch and every of the button can be used to perform on/off operation such as horn, lights, cruise, regen brake etc right?
What is the default max speed limit in the brushless motor controller? Do you change and set the max speed from the LCD display, controller or both? After I set the max speed and I do not want the max speed to be change, is it possible?
The hub motor can still work with the brushless motor controller, even with or without the LCD screen right?
Do you have a similar brushless and gearless hub motor like the one that is:
1) 14″ inch – 16″ inch (including solid rubber tyre)
2) Power is at least 750 W to 1000W max
3) Can implement regen brake, cruise, reverse, set max speed limit
If you have, can I have some details for these hub motors? I need them work with LCD brushless motor controller.

on March 13, 2025Comments Off on Extra wiring connector after install completion
My wife & I purchased an electric 700c front wheel – bike motor kit from you earlier this year.
In my 37+ years working on bicycles the “road bike” brake levers included with our wheel are the first I’ve seen with mountain bike cable connectors.
I’ve completed the installation of the new 700c motorized wheel shipped to us in perfect condition.
I was pleased that the pedal assist bracket and cable were included in the package even though I had to epoxy the pickup to the front bottom bracket housing for it to “see” the magnetized ring portion of the assembly. I use a “five minute” epoxy I’ve been happy with several years now!
I had to purchase and install a new mountain bike fork on our pre-2000 Cannondale tandem to adequately support the electric wheel. I had also to install a rim tape over the spoke head access holes on the wheel where the inner tube fills the space inside the tire. Only the threaded portion of the inner tube valve protrudes from the inner accessible area of the exterior wheel rim opposite the wheel hub. I chose a puncture-resistant slime filled tube to use with the road bike tire on the wheel. Servicing the tire “on the road” with that wheel isn’t a pleasant prospect. I praise God that I have the health, experience and knowledge to maintain and service assemblies of this type!
Question: After completion of the e-bike wheel install and the wiring connections (less the two leads to the yet-to-arrive battery), I still have a white plastic electric connector with 3 prongs within. What might this remaining connector be for?
These days hub electric bike motor wheels are used for e-bikes widely. Nearly all of hub bike motor are brushless gearless. Because of low noise, high efficiency, long life are popular with riders.
Order 1 set 12″ 14″ 16″ 18″ 20″ 24″ 26″ 700c 27.5″ 650b 27″ 28″ and 29 inch hub motor kit, convert your common bike to e-bike is so easy. Directly front or rear drive your bike.
The important part is an engine -hub motor. How to build this electric bike motor?
Step 1: winding
Calculate motor power, speed RPM and confirm what type of copper wire would you use. Next is fix a rotor on the steel shelf, wind copper wires by handwork or machine. It takes about 1 hour to done it by handwork. And should use rubberized fabric to wrap your fingers. Nipping copper wires will break your fingers. If you need steel parts for your building process, then make sure you use the.
Step 2:soak paint
After winding should soak paint in order to be insulated. Use brush to put the insulated paint on the winding and make sure be soaked everywhere. It takes about 24 hours.
Step 3:press axis into rotor
Put axis into rotor winding and use a key to fix axis. Use A-B glue to paste three hall sensors on hub motor rotor, put 9-pin (three pin/each hall) into PCB and use insulated wire to fix it. Put 8-pin cable inside the axis and heavy yellow, blue, green wires to connect the three copper wires(Phase A,B,C) separately. Thin red, black wires are be weld to PCB + and – .
Step 4:paste magnet
Paste magnet inside hub, one N pole, next S pole ..one by one. More magnet, higher torque, more power. The height of our magnet is 30mm,6mm higher than other hub motor. In market,24mm high magnet only build max 500w electric bike motor. So our bike motor works at 36V can reach 750w.
Step 5:install rotor winding
Put the rotor winding inside the magnet hub, be careful hand. It has powerful magnetism.
Step 6:install two covers
Before installing both covers, we should press bearing into cover. Use hexagon wrench to tight screw nuts. When you hear “poop” from electric bike motor. That means install correctly. Done it.
Power on battery and use bike motor controller to drive this hub motor. If no any strange noise. It’s okay. You also need to make sure you have a controller that fits with the model you are working with, or else the whole thing might just fall apart.

on March 13, 2025Comments Off on Check your hub motor wheel – electric bike kit
Order 1 set of electric bike kit from manufacturer-leaf motor and convert your bike to e-bike is a fun. But sometimes when we receive packages and don’t know how to handle it. Follow us:
Before install electric bike kit, we should test it first.
Step 1: Deliver your package
Spent some days on Internet, at last found leaf motor ‘s electric bike kit is the best. Ordered it and paid by paypal. Waiting for… About 3 days later, post officer knocked my door (EMS) and sign in it.
Check packing box first ,if it’s okay. Pls disconnect electric bike kit box.
Step 2: Check all goods in package
Take out 26″ hub motor rear wheel, bldc motor controller, lcd, throttle, brake lever, three button switches, speed signal wire and some connectors from packing box. Check each goods and make sure everything doesn’t have fault.
Step 3: hold on 26″ hub motor wheel
Put the hub motor wheel on your frame fork and tight both screw nuts.
Step 4: install magnet detector
Step 5: connect wires
1.Plug male 6-pin hall wires from hub motor cable to female connector from bldc motor controller;
2.Connect heavy yellow, green, blue from hub motor cable to heavy yellow, green, blue from bldc motor controller, color to color;
3.Two grey wires: connect these two wires/half speed; disconnect them/full speed;
4.Throttle connector is 3-pin that is easy to identify. Red: +4.5V, black: GND, green: Signal
5.Brake lever connector is white 2-pin.When hub motor is working, press brake lever is to cut off power;
6.Signal wire is black three pin plug that should be connected to white three pin female connector.
7.The other three pin connector from bldc motor controller is used for PAS;
8.Connect four pin lcd plug.
Make sure each wire is connected correctly. Power on battery.(Heavy red wire: +, black wire: – )Be careful,36V controller must work at 36V battery, if supply 48V DC, it will break the bldc motor controller at once.
Power on battery and press ON/OFF button on LCD one time, the LCD will light. Twist your throttle,hub motor starts to run. No strange noise…Press brake lever, electric bike kit system stops, loose it,the hub motor runs.
Please watch video .
By test electric bike kit system, we found hub motor wheel, bldc motor controller, throttle.. everything is good. Next step is that we start to convert them on bike.

on March 13, 2025Comments Off on if your lithium battery with BMS or not
Does your electric bike battery has BMS function, if with BMS function,had better to always make this red button to be “down”(Don’t be up)… (After testing, LCD-008HU is no problem for working with the battery without BMS function.)
This red button be “up”, when ride, press brake lever,it will reverse charging battery.
It is necessary to confirm whether the lithium battery has BMS function. If the electric bike battery has BMS function, if the battery is full, use the reverse charging function of the controller, and the battery protection will not absorb. Then the reverse current of 70V, 80V and 110V will be reverse charged to LCD and controller.
The controller has a large capacitance, which can absorb the counter current. But LCD does not have a large capacitance, it will act on the LCD switching power supply and burn the switching power supply.
Other LCD-003 use resistance step-down power supply, reverse charging, resistance can step-down, will not damage the switch.
But for the LCD with USB port, the USB module will be burnt if the counter charging exceeds 70V
Because there are a lot of things that need to be lit for this color screen instrument. It uses the switching power supply. If the reverse charging exceeds 70V, the switching power supply will be burnt out
If your lithium battery has BMS, can’t make that red button to be “up”(three button switch). (red button should as “down” as below picture)
Had better Not use this red button. Thanks.

on March 13, 2025Comments Off on BLDC hub motor bike conversion kit works
We test this bike conversion kit before shipment. If three led lights on throttle can’t work, please connect green wire to the positive of electric bike battery.
About anti-theft, you should disconnect two power wires (one red thin wire and one red thick wire).
Another red thin wire should be connected to a lock or a switch in series.
I find the problem and it’s was the thumb throttle who is not working… I changed the thumb throttle and replace it with the twist throttle and it work fine,,, but I am not satisfied because I prefer the thumb throttle so if I return you the thumb throttle would you send me a replacement one.
I got also another problem in the installation manual online you describe a procedure for anti-theft and I am not able to use it… What is a Cut off power to supply (called soft-switch is turning the key)
So please tell me if I mist something because the bike conversion kit system is not working.
Text for installation guide need clarification
6. Anti-theft alarm setting:
Cut off power supply to hub motor (called soft-switch, but hub bike motor controller is still powered
on) and take out the electric bike battery key, within 10 seconds press and hold the cruise
control button until you hear a beep sound, then release the cruise control button.
The bike conversion kit system is now protected from theft and the hub motor is electronically locked.
Any movement or vibration of bike conversion kit system will trigger the siren for 30 seconds, and the bike motor wheel will resist any pedaling movement.
Was this thin power wire connected well? If did no problem, are you sure that five hall wires from hub motor weren’t be connected well.
Could you try it as below :
Use your hand to turn your hub motor wheel, then turn your twist throttle, maybe do like that, it can turn.
It’s not working. Tell you what I done
Check all the connection three times also check with the diagram all wires and they are OK
Only thing I got: the horn is working and the gauge show full (3 lights) when I turn on the electric bike battery, also when I push two times the cruise button I get a loud beep from the horn and that’s all.
After a road test nothing at all it’s like having nothing at all…

on March 13, 2025Comments Off on I would like to order a rear 48v 1500w hub motor wheel
I really like (love) your hub motors (they perform really well and last a long time) and now I have the time to get the one I always needed.
And here is a very similar bike which also has a 1000W option rear hub motor this one has multiple speeds, most probably 7.
I have asked the rear dropout widths. Will get back to you as soon as I know. And I have a steel frame with a 145mm dropout now which I can widen. I do not 100% understand the trade offs that you are referring to when you say that the rim doesn’t matter, it is the 3 inch tire that is the issue for this hub motor as the same electric bike motor would also go into a wider dropout fat bike which also has an even wider tire – 4 inches. I need more details to understand it more clearly.
And there are other options at the front end of the chain where we can move the chain out a bit:
1. the little chain guide can help – this is mounted to the seat tube to push out the chain from the frame and tire
2. move bottom bracket out to the right
3. or get a bottom bracket with a longer spindle
4. or add spacers between the crank and chaining
What hub motor do you use for your 2000w and higher power fat bike applications? What would I need to change to make any motor work?
I see that the 2000w electric bike motor is 74mm wide which is only 4 mm wider than the 1500w hub motor. I have attached some new pics of my bike from different angles so that you can see how much clearance I have and if I just go with a single speed setup, I will have enough clearance for the chain but in case I need to get additional clearance, I do have some options mentioned previously. So my question now is would a wider or higher power motor work better? I see that the 1500w motor works with dropouts of between 135 and 155mm. And then the 2000w one begins at 170mm. I can widen my dropout and since I won’t be needing the space of a 7 speed cassette, I should be able to have the chain clearance I need.
