electric hub motor power cut out and nothing powers up

Posted by on December 29, 2021 Comments Off on electric hub motor power cut out and nothing powers up

Did you ride it or never ride your electric bike?
1. If never ride,please check if has “-O-“ on the top/middle of LCD screen.. if have, just make brake levers be back or disconnect brake lever’s plug.. then “-O-“ will off, throttle will work.
2. If have ridden 1-2 times,suddenly hub motor Not work.. please smell electric bike motor controller,if has smell from electric bike motor controller.

3. Also, disconnect throttle,brake lever’s plugs from electric motor controller, always press “down” button from LCD, if LCD screen display a “walk person”, aslo hub motor works as walk speed.

This may have helped a little since the hub motor wheel is spinning smooth again, but the unit will still not turn on. Twisting the throttle still does not spin the wheel and the LCD screen still does not power on.

I saw that you left a post on your website about using a volt meter to test the electric bike battery, hub motor, and bike motor controller. I can use mine to test these to help see where the issue might be.

I have not rode it, but the LCD and hub motor only ever turned on once. As soon as I spun the throttle, everything shut off. The LCD does not turn on at all.

I think I sent this video before which shows the wheel slightly spinning, then it just stops. It has not turned.

But right before I did this, the hub motor wheel did spin for a longer time, but the bike motor wheel did not spin smoothly. Then when I tried to show you what was happening in the video, all of the power cut out and nothing powers up.

I used the voltmeter and connected it to the black and red wire from the battery, it says 53V as expected.

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.

12 inch 48v hub motor for electric scooter

Posted by on December 29, 2021 Comments Off on 12 inch 48v hub motor for electric scooter

We are interested in your 12 inch hub motor kit.
What is the max speed available for this 12 inch electric scooter motor. I can use a low speed hub motor on the back and a high speed motor on the front to compensate for the torque at low speeds.

If last time faster speed hub motor is okay.We can make this electric scooter motor to be faster.（about 20 – 30% faster)

I recently put in an order for two rear hub motors similar to what I have ordered in the past.

Can you make the hub motor fit a standard front fork?

Yes,if not install disk brake on this front motor.
We can make it with the same covers.And hub motor will in the center.
But it will takes about 7 days to customize shaft.
It’s fit for standard 100mm front fork. (90mm fork is also okay)

This front 12 inch hub motor only use V-braking system.
We should check if has correct shaft for this motor in stock.If no,it takes about 7 days to customize this shaft.

Yes,we have 48V 18A controller with LCD for this electric scooter motor. (We don’t have LCD with controller)

Please confirm that the following will be applied to the order.
On center with no disc brake
Please make highest speed – 20 MPH speed using 48 Volt electric bike battery.

Please make sure below 1 & 2
1. the same to past order. It’s rear hub motor. Two side covers are the same with screw thread for spokes & flange — (in the center)
2. would you faster than past ?

I am looking to order more hub motors and would like get updated pricing.
Do you still have the information from past orders?

Yes. We still have 12 inch hub motor.
But we found your order is different from standard motor.
Could you take a picture with your 12 inch motor, front or rear ?
What max speed on 36v or 48v?

Purchase electric bike motor for Supermarche Ebike

Posted by on December 29, 2021 Comments Off on Purchase electric bike motor for Supermarche Ebike

I a planning to buy a yuba supermarche here in spain.. It costs 2500 euros.. but with the e-bike system goes up to 5800 total!
How can it be possible that I see one electric bike motor in your website so strong and so cheap compared?

If you can help me with the best setup for my needs I will buy electric bike motor from you:

I would like to be able to ride to the town with stores and buy stuff and come back.The town is 16 km far away going down.. my place is at 250 altitude and the town is at 100 altitude,so i will be going down to the store empty and going back with all the stuff.
I don’t want to feel that i can’t use the bike to its maximum.. so I want a good electric bike motor.
(even dual electric bike motors if possible) and good battery.
So i don’t have to worry about not being able to bring whatever I want to bring.. considering the max 150kg of the electric bike.

We recommend our 48v 1500w electric bike motors with 48v 20ah lithium battery.
About the electric bike motor speed,we can make it with low speed & large torque.

How Long I could ride with that and how fast? could be possible adding another electric bike motor to improve speed at certain moments without loosing torque? How much Would it cost me these 2 options?

About 40km per charge.One 75kg rider ride it last 40km per charge.I mean one 50Kg rider carrying 75Kg of stuff.

Problem with PAS

Posted by on December 29, 2021 Comments Off on Problem with PAS

The reason I did not use your PAS was.I don’t have the tool to remove the crank arm. This one I used installs with out removing the crank arm. Yours is a small ring and would be hard to get the sensor close to the magnet disk. The aluminum ring would not fit my crank anyway, too large. My bike is a 1980 vintage Schwinn.

I am a retired electrical engineer,so I took some pictures for you on an oscilloscpe and meter I own. The signal makes it to the controller because I made the connections at the controller connector.

Image 281 shows that there is 4.2 volts on the red and black wire, which is about right. Image 289 shows the PAS sensor and pickup for it mounted on the bike. The distance between the magnets and the pickup is not critical as I tried several different distances. Image 287 is a picture of the signal making it to the controller as the crank is turned. The upper trace is the 4.2 volts on the red and black wire. The lower trace is the signal to the controller.

I notice that the signal is relatively low only 1/2 volt tall.

I solved the problem. I tried your sensor with the magnet wheel already on my bike. Hub motor works as it should. The pick up with the LED does not put out a strong enough signal for the controller. Yours does, as long as it is close to the magnets. The hub motor are controller are good. Thanks for the help.

The oscilloscope waveform was the only way to tell what was bad. Your waveform goes from and to + voltage as it should .

What does the tool look like for the spokes? The hub motor wheel is a little out of round. Some of the spokes are not seated in their hole on the hub motor so that may be the issue.

question about BLW-20B 20 inch electric hub motor

Posted by on December 29, 2021 Comments Off on question about BLW-20B 20 inch electric hub motor

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 am working on spec-ing out some parts for an electric-vehicle project. I am hoping to build it soon, but I need some information about the hub motor model:BLW-20B. Please see my questions below:
The power rating on the electric bike motor says 1500~5000W. Does this mean there is a range of options I can specify? Does this mean this hub motor will function on this whole spectrum and my electric bike motor controller will determine what the actual power load is?

Is there a product manual for this piece of equipment?
The electric bike batteries I am looking at are rated for a 3000W hub motor. Will these be sufficient?
I am looking for a recommendation on the hub motor controller for this electric bike motor. Could you recommend a part?

We can make this 20 inch hub motor to be 48V 1500W, 48V 2000W, 48V 2500W.
Also,this electric bike motor can work at 60V,72V hub motor controller & electric bike battery… If works at 72V, it can reach 5000W

We have this programmable hub motor controller that can fit for this electric bike motor.(This hub motor controller can work 40V ~ 100V)

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 .
