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.

Brushless motor repair

Posted by on March 15, 2025 Comments Off on Brushless motor repair

Device using a lot of clothing brushless motor, such as DUKEPU, Bedford, heavy machinery and other brands, although the effect of these motors use the whole quite good, but after a certain number of years in use, many motor that comes with a lot of failures. For brushless motor is generally installed in the back-end encoder, encoder, such damage, the general conventional treatment:

First, the wiring is bad; two internal dirty; Third, there is wear the device (including the code disc wear); Fourth, there is damage to small crystal devices; five is the integrated sensor damage.

Through the above conventional treatment can solve 98% of the basic fault. In addition to these failures, the type of motor then there are the mechanical problems, and summarize the general failure of the following:

First, the bearing damage; second rotor problem; third stator winding problems.

Bearing bad can be changed, can be re-burned around the winding, the rotor is damaged, a lot of maintenance staff know what to plant, because these are usually the rotor within the magnetic stripe expansion, resulting bulge out of the metal, resulting in “sweep chamber” problem. So how to handle it?

The way we deal with are: First, remove the outer metal, removing the magnetic stripe (magnetic strip to pay attention to the order, try not misplaced, or re-check a little trouble), clean interior and magnetic stripe itself (be sure to handle clean, conditional You can draw a few prints on the rotor), there are slightly higher at the polished look, alcohol or dry clean pine fragrance. Then, glue (we used a 326), paste the magnetic strip, then glue (we used a transformer plant resin, the specific model unknown), and then paste the glass fiber cloth (optional 0.06mm), gently pull level, so that through the fabric glue. Finally, heat drying (the effect can also be just dry naturally slow, easy flow of glue), and finally is installed debugging.

After the above treatment, the effect is very good, comparable to the new machine, if there is a better way which does not also contribute to what anti-exchange brings progress!

sensorless brushless hub motor at low speeds

Posted by on March 13, 2025 Comments Off on sensorless brushless hub motor at low speeds

Sensorless brushless hub motor at low speeds and easy low-frequency vibration. Vibration frequency and load and drive performance, generally considered the vibration frequency is half the frequency of the hub motor load off. By the sensorless brushless hub motor that works the low-frequency vibration determined by the normal operation of the machine is very negative. When working at low speed sensorless brushless hub motor, generally should be used to overcome the low-frequency vibration damping phenomena, such as the increase in the damper motor, or drive on the use of segmentation techniques. AC servo motor is running very smoothly, even at low speed vibration will not occur. AC servo system with a resonance suppression, can cover the lack of mechanical stiffness, and function within the system has a frequency analysis (FFT), can detect mechanical resonance point, easy system tuning.

29 inch electric hub motor kit have problems with the cassette

Posted by on March 13, 2025 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..

electric bike motor kit – error 01

Posted by on March 13, 2025 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 March 13, 2025 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 March 13, 2025 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
