fat electric bike motor

Posted by on December 29, 2021 Comments Off on fat electric bike motor

With regards to this product 20 inch 48v 2000w rear hub motor beach snow fat tire bike conversion kit.Will my existing battery and brakes work?I have a 48V 14.5 AH battery and hydraulic brakes.
What about hills? Will it work for that too? Also will I be able to use a 52v electric bike battery on that hub motor controller?
Also my current bike, the display has buttons for me to turn on my headlight and tail light, would your system be compatible to turn on and off my headlight and tail lights?
Does that switch plug and play or do i have to splice into the lights and into the controller? I want to use the same battery.
Do you sell just the motor? Maybe I can just plug it into my existing harness and controller?
Also question peter, I heard geared hub motors have more torque off the line than direct drive gearless?

Your 48v 14.5ah battery can drive it work on flat road.
Also,you can use your hydraulic brakes.
If battery’ s current is 30amp or larger 50amp.. can uphill easier..

Work with your 52v battery.
This controller work with 48v battery (min 40v to max 60v) – 52v still 48v battery, just full charged 48v battery up to 52v or more.
Have to splice into lights and battery. Very easy.
Don’t into controller.
Sell just the hub motor is okay. But not sure if works with your controller.
Recommend order motor & controller and other bike parts together.

Now nearly all geared hubs are 250w,max 500w small power.. fit for Europe
We also have these motors.

1000w,2000w geared hub motors are be eliminated by the market.
* too much noise
* low efficiency
* easy to wear gears

Nearly all 1000w,1500W,2000w,3000w e-bike,e-motorcycle use brushless gearless hub motors.

29 inch electric hub motor kit have problems with the cassette

Posted by on December 28, 2021 Comments Off on 29 inch electric hub motor kit have problems with the cassette

I ordered the 48v 1500W electric bike kit, with cassette.
I have problems with the cassette, the cassette is wider than where the dropouts sit around the axle.
So the hub motor wheel with the cassette on is wider than 135mm.
My bike frame is 135mm, and the website said it would fit on a 135mm frame.
When the cassette is on the hub motor wheel and i put the electric bike motor wheel on the bike, the frame grinds against the cassette when I tighten the electric bike motor wheel.
I have made it work using spacers so it spins freely, but the wheel is offset to one side now and i think my frame is spread wider. It is an aluminium frame.
Also the website said max 7 speed gear, but the cassette is for a 9 speed gear, which is also mounted now, is it suppose to be able to take a 9 speed gear, or is that an accident?
Any advice on what to do?
Also, any advice on mounting the torque arms? My frame is aluminium.

Steel is okay.But Aluminium is not good to make it larger. We worry if make aluminium frame to larger will break frame.
We recommend use 7 speed or 6 speed or single speed..

You will receive below goods:
1x pcs of 29 inch 48v 1500w rear hub motor wheel (black spokes, cassette)
1x pcs of 48V bldc motor controller (New version LCD controller)
1x pcs of LCD (New version LCD-003)
1x set of twist throttle
1x set of brake levers
1x pcs of three button switches ( use to control cruise,reverse..)
1x set of pedal assit ( It’s fit for European,if you don’t use,ONLY use throttle is okay )
Some spare spokes with plugs

——————————————-
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.

electric bike motor kit – error 01

Posted by on December 28, 2021 Comments Off on electric bike motor kit – error 01

Before less than one year, I bought electric bike motor kit from you.
Everything is perfect. But today, when I am went to ride, so LCD started writing error. Exactly error 1 , what is fault of twist throttle.
The throttle is always in full position what means that bike still accelerate. I attached photos. I already have behind me exactly thousand kilometers and i started ride from June.

I tried find out where is mistake and I have suspicion that hall sensor inside of throttle is dead. Supply voltage (black+red) is 4,32V what is ok, but output voltage (blue) is in basic position of throttle is 2,0V and full position of throttle is 2,7V. (I don’t know right values)
Can you help me with this problem, please?

Please press “up” to make it be “1 or 2 or 3 or 4 or 5”
Can’t be 0
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 circels,then can drive motor to work)
* Be “2” – throttle works (If install pedal assist, pedal about 2.5 circels,then can drive motor to work)
* Be “3” – throttle works (If install pedal assist, pedal about 2 circels,then can drive motor to work)
* Be “4” – throttle works (If install pedal assist, pedal about 1.5 circels,then can drive motor to work)
* Be “5” – throttle works (If install pedal assist, pedal about 1 circels,then can drive motor to work)

If NOT install that pedal assist, ONLY use throttle to drive electric bike motor. But Should be 1 or 2 or 3 or 4 or 5.(Be 0,turn off throttle)

Disconnect throttle plug..

Always press “down”, if motor works with walk speed.. everything is good that means replace a throttle can solve it.

I tried find a mistake, and I have suspicious on bad magnet inside a throttle, hall sensor is fine, I had him out and he worked good, but if I put him back to throttle, so his behavior is unpredictable.

I think that cable and hall sensor is ok, but last thing is magnet, maybe he lost magnetic..

bike conversion kit torque performance in speed

Posted by on December 28, 2021 Comments Off on bike conversion kit torque performance in speed

A major scientific and technological achievements of my 18 years I found the bike conversion kit torque performance in speed and excellent performance is due to change by the coil – in order to prove the authenticity of my first published the theory – by reversing the DC coil motors, commutation is by phase AC motor. By changing the coil to the premise of achieving the rotating magnetic field in the rotating among each of the stator magnetic pole corresponding to the current conductor always flow in one direction. Can achieve zero speed to rated speed constant torque swing speed, and there is no torque ripple, inverter can be completely eliminated, the chopper will swing popular governor world. Installed on the synchronous motor synchronous brushless DC motor commutator can not be called, is distorting the facts and the scientific community, because it is the by-phase commutation – is the AC motor, it can never find the DC motor torque performance and speed performance .

Rotating magnetic field DC motor, asynchronous motor with a rotating armature of durability and torque performance,sensorless brushless hub motor in speed performance, the performance of the perfect electric bicycle conversion kit, speed DC transformer power does not produce harmonic pollution, Speed ​​costs are very low. It can be raw materials for manufacturing into a more limited market value of commodities, will become the next golden goose, the whole industry will lead to a motor revolution. Engaged in electrical research staff to look at my town scientific and technological achievements, we know that all this is true. Is good to explore the talents of entrepreneurs to create a powerful opportunity.

Product Question of New 26 inch 48V 1000W electric bike kit – front wheel

Posted by on January 1, 2021 Comments Off on Product Question of New 26 inch 48V 1000W electric bike kit – front wheel

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

Extra wiring connector after install completion

Posted by on June 14, 2020 Comments 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?

Check your hub motor wheel – electric bike kit

Posted by on June 11, 2020 Comments 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.

BLDC hub motor bike conversion kit works

Posted by on June 6, 2020 Comments 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…
