- My Ebike had almost 6000 miles on it and from last week it started to make crazy noises and vibrations from the hub motor. And the bike was not riding as smooth as before. It feels like loosing power or something is dragging it from behind. So, I opened up the hub motor and found out that one of the planetary gears bearing was messed up. So I have replaced it with a new one. Now it is very smooth and no crazy noises, just the normal motor noise.
You can see in the beginning of the video (before replacing the planetary gear) the hub motor was making grinding noises and the wheel was slowing down and stops real fast.
At the end of the video (after replacing the planetary gear) you can see that the hub motor is running smooth with normal motor noise and the wheel was keep on spinning for a long time.
great video will soon inspect clean and relube the ones on my daughters bike , thanks for sharing :)
Glad to help
thanks!!!!! I was worry ta break something, have tried to take it off by my fingers but with no results, you save my day!
Thank you
Great video! My hub is making the same noise. I'm going to upgrade the gears to steel instead of the cheap plastic gears. My electric bike is a little over 3 years old.
Alright. Good luck brother
Hey brother did steel gear are working fine or not ?
Die Metallzahnräder sind lauter ! Bedenke das !
@@EbikePOV Heya is this a bafang 250w motor? If so i have the same one on my bike. It’s started to make the rattling noise when I accelerate, decelerate and while in motion. What gear clutch kit can i buy to replace it? Are you able to provide a link? Thanks.
Damn, I can still hear the bearings rumble. I just bought a new ncm ebike, and I think there is something wrong, that it should be quieter.
That e bike is a work of art. What is with the big screen? and the seat.
Thank You. The big screen on the top is a tablet for navigation and music. The screen underneath is a rear view dash cam.
question: at 3:26 you're putting the gears back on but the video skips. What is the trick to get the gears back onto the axle? I am stuck at this stage; they only slip on about halfway to engage the main gear but won't slide any further on. @ebikepov
Mine was easy to push it in. Try to wiggle the clutch assembly while pushing it in. Or try to spin the clutch assembly/gears while pushing. That may work. Thank you
@@EbikePOV turned out my axle had a tiny crack from the stress riser where the key block presses on the edge of it's slot. That crack was enough to make it a bear to get the clutch assembly back on. I ended up filing the metal a tiny bit, then everything fell into place.
Good. Thank you very much for sharing.

Thank You
excellent, thanks!
Thank you
Did you have washers between the bearings and the axle when opening up the motor. My motor does and stops really quick there is so much resistance
Hello friend, The resistance I think it is from the dried up grease in between those white planetary gears and the steel clutch that holds them. It happened to me two years ago when there was only 500 miles on my bike. I have noticed the noise from the motor got louder and there is a lot of resistance from the motor. It was not spinning freely and stops real fast. And when I ride, it was so hard to pedal (feels like something is holding my bike from the back). When I opened the motor, the first thing I noticed was, there was a lot of white lithium grease all over the motor. They have probably over greased it when they assembled the motor. And there was also a lot of grease settled in between the gears and the clutch housing. You know when these gears are over greased - the excess grease will gets out of the grooves and settle in between the gear body and the clutch body. The space in between the gear body and the clutch housing is very thin and we don't need any grease there because they are not touching each other. But the excess grease gets in there and creates an unwanted friction. During the time, the friction will cause them to heat up and dries up fast, which causes the resistance.
Anyway, I have cleaned all the old grease out and applied new grease. After that the motor was kind of quiet and the wheel started spinning freely.
Try it. But DO NOT OVER GREASE
Thank you
@@EbikePOV Thank you very much. This is a lot of valuable information. I have to get those planetary gears off. The motor spins freely with no resistance out of the case but the moment I put it back into the motor housing it becomes really hard to turn
I found the reason for the huge resistance. The clutch provided with the bike is very stiff turning I will replace it if i can't get it rotating freely
@@bogsquatch6782 All right my friend. Good Luck 😃
Hello, how do you know the planetary clutch to buy for replacement? I want to change mine but don’t know the right one to buy and my supplier isn’t helping.
which bike do you have
@@EbikePOV i have an anioki aq 177 pro with a 750 watt motor. I bought one of the gear replacements and it just sticks. Someone said the gear was reversed? Do you have a link to the one you bought
How do I find out what size gears my magnum pathfinder has in the rear hub
I am not sure about that. It's very hard to guess what size gears they are using by just looking at the size or wattage of the motor.
In my case it was a 750 watt rear hub motor. When I searched online for "750 watt rear hub motor planetary gear replacement" I saw a lot of them. I bought two of them ( one nylon and one steel ) without even checking the size of the gears. I thought 750 watt hub motors use the same size gears. But I was wrong. The gears I bought were 38mm. But the gears inside the motor was 47mm. Then I searched online for that particular size and I got the exact fit.
So, I will say, contact the manufacturer and ask them what size gears they are using. Or take your time and disassemble the rear hub motor and measure yourself.
Hope this helps
Thank you
EbikePOV
I have a Bafang rear geared hub motor... are all these Planetary Gear Clutch Replacements interchangeable/universal? My motor is labeled "RM G0F4.D" and looking it up it's a 1000w motor, although it's marketed as a 750w motor. It's in the Ride1UP Revv 1, that's my bike. It's very noisy and I guess they all are but it's only a matter of time before it goes I'm sure. I'd like to spend the $40 to have a backup set if it craps out on me. Do you know if it's a universal interchangeable part? Thanks.
Following
Word of advice, i bought a 3 arm bearing puller and the clutch came straight out with ease, was worth every penny
Thank you
Hey l guess i have broken teeth in my bearings, do you recommend to change them? Thank you great video btw
If you are sure that your bearing is messed up, then you should change it.
@@EbikePOV thank you for the reply, l did help and now it's smooth as before!
@@zukhriddinmakhmudov3793 Great. Good to know
My bike would make noise only sometimes and would go away if I cut the power to the motor and then re-apply power. I think one of the bearings was a little loose on the nylon gears, replacing the whole one way clutch and gears assembly fixed it. Now its quiet like new! I used mobil 28 grease. I also used a tool called "impact driver" to loosen the Philips screws without stripping them. And I used a 4inch gear puller to take off the clutch/gear assembly.
Thank you
Where can I find the little metal square that goes in between the gear and motor
I know what are you asking ( key / lock ). I am so sorry I have no idea where to get it. I searched online for it and I cannot find anything about it.
Any advice on planetary gear? Is metal better than the nylon ?
I am using the nylon ones. After the replacement which is on the video, I have put about 7000 miles and it still going strong. Actually it was not the gear that messed up, it was the cheap bearing inside went bad. So, what I did was, replaced the steel bearings with ceramic bearings. It's less noisy and way stronger and smoother than the steel ones.
Regarding your question, nylon gear or metal gear...? I don't have an experience with the metal gears. So, I don't know which one is better. But you can search online to find advantages and disadvantages between them.

Did you replace the gear on the motor shaft?
No, I didn't. I didn't have to. The planetary gear clutch assembly just fits in.
Heya is this a bafang 250w motor? If so i have the same one on my bike. It’s started to make the rattling noise when I accelerate, decelerate and while in motion. What gear clutch kit can i buy to replace it? Are you able to provide a link? Thanks.
Hello friend, I do have the link. But, please make sure what size is your planetary gear clutch system is. I said this because, two of them I bought was not the size what I needed. It all look same on the picture, but different sizes.
Following are the descriptions for my planetary gear clutch system. Yours may be different. So, please make sure by measuring the clutch diameter, nylon gear tooth count, and so on.
Nylon Tooth Gear Size: Outer Diameter: Approx. 47.5mm / 1.87in, Inner Diameter: Approx. 8mm / 0.31in, Thickness: Approx. 13.5mm / 0.53in
Clutch Size: Outer Diameter: Approx. 88mm / 3.46in, Inner Diameter: Approx. 15mm / 0.59in(manual measurement allowable error)
Nylon Gear: 36T
Applicable Motor: 500W-750W
www.amazon.com/gp/product/B09V5M7DJF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
What I recommend is, before you order blindfolded it's better to open up the motor and check what exactly is causing the noise. At that time you can measure all the specs of the clutch system and get the right one.
Good luck my friend
@@EbikePOVthanks alot for that. That’s exactly what im going to do.. open up the hub first. Thanks for the link aswell. The ones ive seen all over ebay are the 36teeth ones. But I’ll be 100% sure before i buy. Thanks again.
Is there any ring on top to take out the planetary gear
. I try to take out but not successful
There is no ring. But the gears are really tight to the axle. So, its better to use a gear puller.
Amigo, aquí de nuevo, llevo un mes esperando material de Aliexpress que no me llega para sustituir los 3 engranajes de plástico porque uno de ellos tiene rotos 5 dientes y me hace ruido extraño cuando circulo en bici, de momento solo he desmontado del motor lo que he visto en tu vídeo en el minuto 1,50 y que ha sido muy sencillo gracias a tí y es utilizar el alicates y una maza y con unos golpecitos, ¡bualá! a salido fácil el segmento de los 3 engranajes sin necesidad de la herramienta específica que existe para extraerlo, ahora a ver como extraigo el engranaje del segmento porque tiene una horquilla metálica que lo sujeta y no sé como hacerlo, mil gracias y sigo a la espera del material.
Amigo, Puede utilizar los alicates para anillos elásticos para quitar el anillo de seguridad que sujeta los engranajes. Simplemente busque alicates para anillos elásticos en Amazon. Aquí hay un enlace

Nothing was wrong with the old ones a little bit of noise is is good but thanks for the video
You know, when the motor runs smoothly without any issues, there will be no sound. When there is sound coming from the motor, that means there is something unusual going on in the motor.
I have a gazelle bike, i disassembled it the frontwheal, but couldnt open the motor, i took all the bolts but couldnt open it, what do you think i should do ?
Hello Rad, I am not familiar with that bike and I am not sure what to do to fix your issue. Try searching on Google and TH-cam. You will find something somewhere. Good luck brother.
@@EbikePOV thanks ❤️
hi, whats the purpose of putting grease? on the planetary gear and etc?
you know it
How many globs of grease did you use and did you just put grease on gears?
Yeah, I put the grease on the gears. Because they are the moving parts which touches each other causing the friction. To reduce the friction, we apply grease. How much....? just enough to coat a thin layer on all the grooves of that gears. Since they are nylon gears, a thin layer is good enough.
Thank you
@@EbikePOV what type grease?
@@pauly51 I used the mobile grease 28. www.amazon.com/Mobil-Mobilgrease-Aviation-Grease-MIL-PRF-81322/dp/B00G3BTV5A

Sorry I thought these were the right ones in my early stage of investigation I now realise I need helical but thank you for taking time to reply means a lot
How hard is doing it with no experience? BTW great video!
Just watch some videos about it and you will know what you will go through. Just be patient and careful. Its not that hard to do.
@@EbikePOV alright, thank you!
Does anyone sell planetary gears for bikes that have the cable on the left side?
Not Sure
i dont know if hammering on the axle is a good idea as you can damage the end of the axle so that the torque plate wont go back on.
many ebikes come with a very basic torque arm that is a teardrop shaped piece of metal that goes over the axle and bolts to the frame.
the torque plate is made so precisely that there is not much room to fit so you may not be able to get the torque plate back on.
you are better off using a gear puller.
You are right. Hammering can damage the end of the axle. I should have used a rubber mallet
Thank you @ejonesss
I just did this today and used a gear puller. With that, you don't even need to use a spanner on the other end. Because it's evenly pulling, I was able to do it by just twisting the puller axle by hand. But the clutch was pretty tight in there when I went in with other stuff.
Hey mate I replaced the gears but now it’s just a humming noise and the gears arnt catching I was told they are in reverse how do I solve this issue ? Thx !
So sorry for the late reply. It shouldn't happen like that. Send it back and get a replacement or buy it from other seller. Thank you
I have a 1000w g062 motor. I put in a new clutch and gears but when I throttle I hear the clutch spinning inside the hub yet the wheel doesn't move. Suggestions?
So sorry for the late reply. Not sure what's causing the issue. Maybe its a faulty clutch. Try to replace it with a different one. Thank you
@@EbikePOV I figured it out. i bought the wrong clutch that spun the wrong way.
There you go. Good to know you figured it out. And thanks for sharing
I’m having this same problem right now. Can you please let me know where you ended up finding the right clutch?
@@TheAlvesFamilyy i used the same clutch. the new one i bought spun the wrong way. I replaced the planetary gears, i got the gears off aliexpress, 38mm is the diameter.
Hi I have a problem with my motor when I’m on the bike the motor stops working and how I get it to go again is I have to rev it and push the bike backwards and the motor clicks back in the gear then I go do a bit longer and I have to repeat the process it’s annoying can you help it’s a 1000w motor thanks
Hello Lee, If you can upload a video of whats going on, that will be great. Thank you
Can you make a videonstep by step to split hub gear of chain from the motor part. I tried hard but unsecessfull remove that to replace the new stator❤❤❤❤
Hello my friend. I am so sorry that I don't really understand your question. Try to watch these videos.

Can’t get my clutch to come off
Try gear puller. That's easy. You can search for "gear puller" on amazon. There is a lot of them.
Reason for replacement?
Motor was making crazy noises and the wheel was not spinning freely. When I spin the wheel, it stops real fast. Out of the three planetary gear, one gear's bearing was messed up. I think that's because my bike is kind of heavy. Now it's really smooth. Hope this answers your question.
Hi. My motor started making noice too, if i dont change this gear, it will work or it will stop working soon?
If i dont care about noice
It all depends upon what kind of noise you are hearing from the motor. You know, all the hub motors have a humming noise. That's normal. If that humming noise gets louder - that means there is some kind of resistance in the motor - which is caused by 1) low grease 2) too much grease or 3) dried up grease that settled in between the gears and the clutch body. All these causes a little resistance and louder motor noise. If you dont care about the resistance and the humming noise, then you dont have to worry about that.
But, if the noise is kind of rattling, then you have to open up the hub motor and check out what is going on. There may be broken parts inside.
In my case, one of the nylon gears bearing got messed up. That's not normal. It happened to me because, I have a lot of stuffs on my bike which makes it very heavy. That's why I changed the whole clutch assembly.
Hope this will help you
Thank you
what's your e bike model name?
I dont know which brand is it. I bought it from aliexpress.com. There is a lot of ebikes on there website with no brand name or model name. On the description it was saying 750 watt fat tyre cruiser bike. There was no name on the box or on the bike either. There is no branding on the motor either. I guess its some generic brand
Thank you for your reply! Though I searched the Aliexpress website, but I couldn't find a similar model..(20inch?)
I'd appreciate it if you could let me know the purchase link for the model.
Hello friend, so sorry for the late reply. I just noticed it.
You said right. I cannot find that link either. My purchase history for this bike was linked with my old profile which was deleted because of some issues with aliexpress. So, I was not able to access that particular order. I bought this bike back in 2019. At that time there was a lot. But now, I have searched their website for a similar one but I cannot find any.
I used a picture of my bike on Google Lens and found some similar ones online. I will list them below

U not worth my time bro u skipped the part I needed 😂
and where did I buy mobilgrease 28
I bought that from ebay. You can search it on Google shopping
@@EbikePOV thank you very much.
He's using a mobile grease I use a marine Grease
Why?
good
@@EbikePOV Is marine grease better?
I don't really know which one is better. When I searched online, it says marine grease are waterproof. Other than that it still the same. I have used mobil grease because it is way better than the white lithium grease that the bike came with.
Clutch? What clutch? There’s no clutch in there, is there? It’s a motor and gears.
I watched the video and didn’t see a clutch. Do you understand what a clutch is?
Why are you mad...? Please look at this link www.amazon.com/s?k=planetary+gear+with+clutch&crid=QPX9ZEL0XR9O&sprefix=planetary+gear+with+clutch%2Caps%2C78&ref=nb_sb_noss_2
