Put the nut on that axle before hitting it. You are damaging the threads. Every mechanic SHOULD know this.
With these little dings nothing will happen, I know that MIGHT damage the threads and still do it with way more force
I managed to 2 times damage a thread in probably 100 times. And both times I just slightly dremeled that thread slightly on the dinged end and screwed it in no issues with a drill
Humans are lazy, just how it is
I would have used a piece of wood in between and hit the wood instead.
@@Another-Address rubber mallets the best choice 👍👍
I second this. I cringed when he just did that
What he should’ve done is use a rubber mallet or Hyde mallet
After two days of trying unsuccessfully to rebuild a motor I came across your video which is the only one that ever mentioned the little pin on the planetary gear set, I looked around and found it, put it all back and it worked, you saved me from a really uncomfortable situation with my girlfriend explaining how I broke her bike by fixing it lmao, thanks a lot !
Glad it helped!
Hello Brandon, you have great courage to go near it. I wouldn't touch it with a ten foot pole. We gotta keep our gals happy . Bikes and birds. Keep em rolling ❤😂.
I have a Yamee ebike with 6000 miles. Last week the hub started to sound like a piston knocking. I was at a stop light today and when I went to take off the rear wheel froze up. I watched your video then took the rear hub apart to find all three of my white plastic clutch gears were broken. I ordered them on Amazon and will have it fixed in two days. Thank you for making this video.
I'm glad the video could help Kenneth!
Did you have the option to choose between steel or nylon gears
@@ferguson8143 I had to return the Amazon wheels because they were the wrong size. The only place I could get the correct size was Alibaba. No, I did not have the choice to get metal or I would have.
I love my Rize X with hub motor. These videos are too hot. I watched a BUNCH of youtube videos and tried to learn actual knowledge. These Rize videos are just the Best of the Best! I am very happy customer, the march 2023 Rize X model is 2x better than the one shown in the videos!
Thanks again!
Glad you like them!
I'd like to see a tutorial on how to take the center of the hub out where the wires are if the wire has been damaged just outside the bolt on this wheel
Thank you for this video! As someone already pointed out, you are the only video that mentions that CRUCIAL little pin that locks the planetary gears to the axle. One thing that I thought wasn't clear and hopefully this helps someone else is that the pin doesn't actually go into the planetary gears, but actually on the side of the axle itself (it just pops right in with almost no resistance). If you look at the axle you will notice a perfect indentation for the pin which will then allow you to line up that notch in the planetary gears and it fits together seamlessly. Another thing I didn't see mentioned and this may be model specific (mine is a Himiway Cruiser), but there are thin gold washers that go on after the planetary gears. I had slight play in my axle from side to side after tightening everything back up, but I needed to add both thin gold washers very last before putting the motor back in the hub. Just those 2 thin gold washers tightened everything back up and there was no longer any side to side play. Thanks again!
Glad you were able to get assistance from our video and great suggestion!
Thank you sir. Clear explanation on how to. Hope more videos are coming.
Thanks Keith!
You never hit the end of the axle without a nut on it. That is basic engineering.
Thanks for the video! Your instructions worked great for a Ride1Up 700 w/ a Shengzi hub motor.
just the vid i was looking for,cheers
Great video. Thanks
I just got confirmation that the Jinghma manufacturer is sending me a New hub motor for the Jinghma R7. Cant wait to take it apart and replace the motor. Will use your video to do this
How frequently is a good idea to open the hub motor and put grease in it at the planetary gears?
This is purely dependent on how much it's used and how long time passes between rides. If you use it seasonally, for only a few months of the summer, we recommend re-greasing it when you pull it out of storage and do a general tuneup, as well (bleed the brakes, oil the gears, oil the chain, etc.). However, if you use it all the time, we recommend you service it every 1000km or so. If the motor seems to get louder, grindy, or making any other odd noise, it's time to get a check up done. Good luck!
What type of grease and brand do you use for hub gears?
In our shop we use a generic brand of Lithium based grease with a listed NLGI 2 rating (rated for high temperatures). There is no perfect grease or major standout for brands. When looking for grease you want to find a grease that follows these guidelines: NLGI rating of 1 to 2, able to withstand high heat and friction, ok for metal and nylon gears, water resistant.
This dude makes honor to the brand! Very good quality content and production :)
Glad you've enjoyed your video!
Is there a service interval for that particular motor? Wondering when I need to grease the gears as you've shown. Thank you.
Very nice tutorial, is it possible to change the part of the motor wheel that fix the disc brake, is it complete part of the motor wheel box or could it be bought online ? on my minifatbike this part is destroyed the screw holes are smatched, I just put the screws back on the not too damaged screw holes but it's a temporary repair
Nice one Craig. Now I know how to do it.
This video helped me a lot i have a e bike and was not comfortable pulling apart my motor but i just followed the video and it worked great, i just need some new planetary gears cause i cracked one of mine from trying to go up to steap of a hill
Well done!!!
Nice job!
Trying to get a backup rear wheel so as one has a problem I'm still able to run the bike by swapping wheels and fixing the other one so there's less downtime if the bearings give out again
Have you replaced the bearings I need to do mine is it a easy job?
Thanks for this.
Thanks for the great info
Glad the video was helpful!
Do you have a video on how to rewire the inside of the hub whereafter the group of wires get ripped out?
This helped out a lot thanks for the tips great video
Thanks I need to know this stuff I got a regular commuter ebike rize not city and love it
I also changed the S866 display settings for the "Help start intensity setting" from 3 to 1, which I think/hope means it will pull away more softly. I thought that might help.
"Don't slam it, you just want to bang it." Got it! 😂 ...this is actually a great video. Thanks!
Thank you for this video. You helped me to realize the 🔑 was super important.
Glad it was helpful!
Thank you ,
can this method work for the walmart ebike hub motors for say replacing a bearing
Ty so much my dude
Thank you so much , do you have any video teaching how to Change the shock absorber ?
Hello Mike,
Do you mean the front fork? We do not have any yet but it is in the works to be publicated soon.
Do you have a video on replacing the motor wire?
Thanks Rize Bikes, this is a great video! Any suggestions on the torque value of the hub bolts? Thanks. I'm a subscriber thanks to this video!!
We don't have a specific torque value, but would suggest as tight as you can without stripping the bolts. We also suggest using Blue Loctite with it.
Thank you for this video. Do most stock fresh from companies e-bikes come well greased?
Hello Pauly,
Yes, brand new motors from Bafang should come well greased. We simply use them on our bikes.
What size bolts are needed? I have a 750w hub with only screwed in 😮
Hi, thank you very much for your video, it’s very helpful; can I ask you where to buy the electric cable taking the electricity to the motor? I have a SAMEBIKE 20LVXD30, I live in London and I have been unable until now to get one, thank you again and sorry for my question!
We recommend reaching out to the company you purchased the bike. They'll be able to help you out.
hi do all hub motors have lock tight bolts that you have to use that tool to open the hub? how would i know the difference that i need that tool for a bolt or a screw, thanks for the vid...
Hello Ray,
I cannot speak for all hub motors, but the BAFANG motors we use are like this.
Is there a recommended torque value for the bolts to the motor housing (the "locktighted" ones)? Nm please.
Hello Jerred,
Unfortunately Bafang does not provide the torque setting numbers but we would say just hand tight and not any more as you may risk damaging the threads.
Hey man ik I'm super late but how do you get the clutch/gears off to look at them individually like you did, do u need a special tool or do u just force it off,and if u force it will it go bacl on?
All you need is C-Clip Tool.
Very good video, from your experience, should there be some humming noise from the gears when the bike is on a stand. TIA
Generally, your motor will always make a noise, be it on road or on a stand, a hum can be fairly standard. Take care
What about applying some more locktite to the six bolts so they don't come loose?
These screws hold the cover that spins with the motor. They're not load bearing, just securing the dust/water cover. Loctite is a good idea but not strictly necessary. :_
@@fraserthomson5766 Considering that the axle and rim act as a the stator and rotor, those bolts are transferring force between the axle/stator and the wheel/rotor.
My motor having some sound due to planetary gears.. do u have the video how to change the planetary gear? and is it better to change to the metal one for long lasting?
Hello,
We have videos on our channel on how to change the planetary gear on different models of Bafang model found on our various eBikes!
We recommend you stick to Nylon as that was the intended configuration from the manufacturer. Metal gear motors are a lot harder to service and maintain, as well as being a lot noisier during usage.
@@RizeBikes I would also assume that if anything is going to get damaged or worn out, you would want it to be the cheap nylon gears, rather than the motor/hub itself.
I need to replace my bearings on my bafang motor like this is it a wasy job?
I wouldn't be hitting the Axel like that that's for sure 😭 UK 💋👍
Hi do you have any vids on how to change the planetary gears of they are worn .
I changed the planetary gears several times. You can replace the whole set or only the gears using a screwdriver and fingers. But mostly, to remove the planetary gear set from the motor you need a puller. A tool that catches the set and screw it off the motor. I was never able to remove the whole set with my own hands.
You are teacher MAN!
Hi thanks for the great video, can you please tell me the size of the 6 bolts , thank you
Me too I wanna know what are the size
If you know let me know please
Hi Craig I loved the video thank you. May I pick your brains on a matter please? I have a Lafly x5 fatbike with 1000w motor. After 1 year, (and me changing rear tyres and probably not fitting the wheel back in properly or tightly enough) I suddenly came across a debilitating fault, where the spindle, appeared to be turning inside the frame, maybe the washer and mangling the power cable which just pulled out of it's connection. I saw the drop out corners were damaged and I paid a solderer to repair it. He did a good job. But it didn't work. That's when i realised it was turning inside the lock washer, the one with the hook that goes into the drop out. I ordered a new pack handed it to the bike shop, and they fixed it all together. It worked! They also serviced it and made everything 100%. But now after 2 days, I've noticed the spindle with the flat sides has turned at least 30-40 degrees. It seems to turn a little bit maybe 3 degrees every time I go out on it. I'm beginning to wonder if its the spindle itself because the flat edged lock washers are new and stainless steel. So I don't want to throw the bike away, it's perfect in every respect. Please help me to save it. My idea was to buy another pack of washers and put lock washers on the outside of the frame as well, both sides. Just an idea. Desperate, as most bike shops don't want to know. The last bike shop will take another look but I want to research answers for them.
Hello,
We know you're having issues with your Lafly bike but if they are unable to assist you, please send documentation to us at support@rizebikes.com and our technician will take a look at it.
Hi there where can i find rotating plastic part with wearing today I opened my bike rotation part are totally flat . It has not any teeth now can i change or i need to change full motor
Hi, please email support@rizebikes.com Thx!
Can i replace the motor cable? Some cut mine and i reconnected them but no succes
What if my motor cable is on the other side of the cassette? Do I still hammer the axle end opposite to the cassette? (Motor is labelled HLGE2)
yes
Yeah I put new nylon planetary gears back in it. on this motor there's no clip that holds the planetary gears in place. just the outside cover so far so good no noise
I changed the planetary gears several times. You can replace the whole set or only the gears using a screwdriver and fingers. But mostly, to remove the planetary gear set from the motor you need a puller. A tool that catches the set and screw it off the motor. I was never able to remove the whole set with my own hands.
Is it recommended to use locktight when putting bolts back?
Hi Gord, you can use loctite if you feel the bolt is loose. Key thing to remember is that you may want to unscrew the bolt in the future so, make sure not to over do it. Take care!
I'm thinking this is damaged on my bike. it's making a grinding noise. was thinking it was the ball bearings but not sure if electric bike has that
Great video.
Question, do all geared hub motors have that planetary pin to hold planetary gears in place? I see some type slot on my gears but I'm not sure if the pin you're talking about is a part of my hub as well
Also, if I somehow misplaced this small pin, where can I order a replacement part outside of OEM, or can I make one? Great video.
/bklyn 👑
When In a pinch, you can make one from scrap metal and angle grinder/dremel too, cut/sand/grind till the "pin" (Shaft Key) fits, you going to want to heat treat it, use a blowtorch heat till glowing red, dunk the piece in any oil, even vegetable oil, let cool, put in place.
Just cut a bit of a drill bit of the right diameter and length.
@Rize Bikes how do you repair a hub motor power cable that has been cut in half by the disk brakes? Also where can you buy the wires? And how can you prevent the disk brakes screws from getting loose and damage the power cable again?
How did you even manage to do this... probably just get a New motor, then replace as this vid says
You need to show some pictures.
@@ElCeeKaa The screw that were holding the rear motor wheel got loose and the disc brake sliced the power cable in the back. The chinese seller on aliexpress of speedbike use the wrong screws to secure the wheels..
How often should this be done ?
good day friend, I bought a front 26 inch 500w motor for a fat bike, but I have a 27.5 inch wheel on my fat bike, what is the loss of engine power if it is on a bigger wheel, it will be a noticeable change in engine power, thank you in advance
Won’t be by much the tires are close to the same size
Slightly better acceleration, slight loss of top speed. Basically negligable difference
Hi could you tell me where I get the t20 wrench and it's full type, cheers, appreciated
We recommend picking up a set by Park Tool!
torx T20 3/8th inch drive socket bit attached to a 3/8th inch drive ratchet wrench.
The cable that goes through the nut, what is that called and how do you go about replacing it? Mine is damaged and I haven't been able to find any info.
Hello Michelle,
That is the motor cable. If it is damaged, you will either need to replace the motor or have a skilled person repair the wiring or replace the wiring by resoldering a new wire into the motor itself.
Please contact us at support@rizebikes.com if you need assistance.
My motor didn't have torx, it had philips, I used an "impact driver" to get them loose.. If your screws seem stuck too tight.. .get an impact driver..... Impact driver will save you tons of headaches on tight screws...
That makes me think I could potentially swap out spoke wheels for a split-5-spoke type... IS that possible? I bought a Grizzly but never was a fan of spokes. I'm curious if this is doable.
If you look up the Bafang H500W it has rims like that. But i think the motor and rim need to be designed together. Since the outer shell of the hub motor is built into the rim.
@@EBikeBuilder_ I'll have to find a shop (I don't think we HAVE any in Tucson for eBike gurus) and start taking measurements eventually.
On 3:03what would be the right proces to putting the locking pin back do i just push it in with my fingers??
Yes, you can use your fingers. Be well
@@RizeBikes it is in table under the left wrench
I wonder where you get that special torque set
Probably go to a automotive store or online. I am currently trying to drill a hole in the center of a torx bit myself. See how that goes I guess
I couldn't help but cringe at him hitting that axle with a steel hammer.
at least use a rubber mallet or other soft hammer. Or alternatively just hit the wheel against a wooden plank on the floor to break the grip of the hub
Great video.
Question. I have a cracked hub shell (20" 500w) but my motor works fine. I've looked online for the hub shell itself, but only see listed the full motor with hub shell.
Can hub shell be replaced alone? Do you have the name of some vendors? Can u steer me in the right direction? Hope u can help.
/bklyn 👑
if it is bafang hub greenbikekit may be able to help. Or there are some sellers on Amazon such as Accolmile that have a close relationship with bafang they can sometimes do custom orders
Also remember to check the clutch on the inside of the planetary gears. It is a vital part and seems to go unnoticed in discussions.
Hello Jessel,
Good note! We have videos coming up about how to open your clutch, as well as how to grease or replace the gears inside.
Question are the 2 axis move independently? Because when i see the bad part rolled the axis spins but not on the other side ....anyone know whats wrong ( this is part 2 of my question) can anyone help with a solution
Any reason why they don’t go with a direct drive motor? Wouldn’t that be less maintenance? I spoke with a guy who changed the planetary gears in his blade 4 times.
Hello!
A planetary gear setup is more cost effective, smaller in size and weight, and easier to maintain. Planetary gear setups also have higher torque on the low end compared to direct drive which is where most eBike's shine the best, in stop and go riding (Think riding in your local downtown), and finally, planetary gears get more km out of the same battery vs a direct drive.
@@RizeBikes ok makes sense. But is there any way to insert a grease nipple so you don’t have to take the whole things apart every 2000km?
*The very fact you make a detailed video to show your customers how to service the quality Bafang rear hub motors on the E-bikes you sell demonstrates you are a decent E-Bike retailer. This market is severely underserviced in Canada, with many sellers out there who are sketchy at best. The Electric scooter market in Canada is practically non-existent. 😳If you are in Canada, things get very opaque and frustrating, when it comes to shopping for an electric bicycle, and downright nearly impossible if you want an electric scooter ! 👎🏻👀 I sincerely hope Rize will get into the electric foldable, portable Kickscooter with seat option market segment soon as well. They make quality E-bikes ! 👍😃There is a great need for a small (under 30 lbs) foldable, portable, electric kickscooter for around ($995.00 to $1,500.00 CAD). In my extensive and ongoing research as someone who's looking for an alternative EV solution to my now unaffordable car, I'm coming up with next to nothing in my own country for this market (??) 💁😳 EVERYTHING IS MADE IN CHINA ! 💁😳😳😳 Chinese e-scooter companies are online only, you can't call them, as they don't want to know you or deal with you, they just want to get your cash and drop ship a bike from a central warehouse onto a ship. The ship takes 2 weeks to reach North America, then an extra 6 weeks to get it onloaded onto a truck just to enter the ground courrier or Canada Post Mail System ! IT'S A FREAKING GODDAM NIGHTMARE !!! 👀👎🏻👎🏻🥺🥺🥺This is no way to do business if you are in Canada, and just want to buy an alternative E-Bike or E-Scooter, but is the perfect operation for them, because you're dealing with a shadowy dude who sits in his appartment in front of his laptop ! 👀👀🤨. May I just say as a customer I am not impressed ! 😡😡😡😡🤨🤨🤨🤨👎🏻👎🏻👎🏻Forgive the length of this post, but I needed to get this rant off of my chest ! I'm glad to see Rize supporting Canadian Customers, because this market frankly SUCKS BIG TIME !!!😡😡😡🤨🤨🤨👎🏻👎🏻👎🏻💁👀👀 P.S. I forgot to mention that trying to buy from a US retailer of E-Scooters or E-Bicycles is also another goddam freakin' nightmare ! 😳😳😳After speaking with several US resellers I am hearing the same, familiar phrase over and over again - "Sorry, we don't ship to Canada." 💁👀👀👀*
What is the torque when reinstalling hub bolts? Or does it matter?
Hello Eric,
The hub bolt should be torqued to at least 25nm. Do not exceed 40 to be safe as you can damage the axle.
If the wires that go through the axle, to the motor, have frayed and snapped, how would you go about repairing? I can't solder, because the cut wires are too deep inside of the hollow axle.. am I going to have to replace the whole motor??
Hello Andrew,
Please contact us at support@rizebikes.com and one of our technicians will be able to assist you.
I would open up the motor and try soldering new wires to the old wires, depending on how they're connected to the motor (probably on a little board) i might consider desoldering or getting as close as possible to the existing solder joints of the old wires and I would go up one gauge on the wires and get quality wire maybe a dedicated ebike cable with the right number of strands or maybe silicone jacketed wire, i think sometimes the wires they use could be a bit beefier considering most motors pull 500w and up and having thicker wire might help it be slightly more efficient and prevent them breaking, the silicone or other high grade insulation would also help
I had the same problem with my engwe engine pro. I (correction .my bike mechanic did, big shout out to Dan in inner city scooters Dublin Ireland ) replaced the lead completely from the hub motor to the connector. He also replaced all the sensors. 250euro ooch. Worth it though. Great bike.
Hi bro my bafang hub motor is 9 speed cassette and my bike is 7 speed cassette now I don't know what to do can you please tell me thanks
Just put the 7 speed cassette on lol
Any issues going to metal planetary gears, besides the noise?
Weight😊
The planetary gears are the sacrificial part. To save the hub inner from wear. Easier to change them than the whole hub.
I have a problem with the frame itself the socket the holds the axis of the motor is rolled the axis keeps spinning and almost damage the cable kinda did but where the cable comes out is has like a separate metal thing holding the axis but on the other side the frame is not holding the axis in place ( is an old bike ) the ideal way would be welding a piece of metal into the frame socket but i don't have a welder... epoxy?
Sounds like your dropout got eaten away by the axle because of torque. Epoxy wont work, i tried that solution when i experienced what you described. Try to buy good steel torque arms.
Is your current bike frame aluminum or steel?
Stop having any faith in this as soon as you hit a threaded spindle with a hammer, just put the nut back on to hit it.
hi there ive taken mine apart cause of a skipping grinding sound so assumed was the gears but they look fine but was thinking i should get the plastic ones replaced and re-grease them and would that perhaps fix the problem (has also lost a lot of power) thanks for any help
Hello,
Typically the noise generation and power is governed by those nylon gears inside the motor and they do require maintenance. Customers with issues down the road with their motors typically get it resolved by replacing and greasing those nylon gears.
Is it true that a lot of people are going through more hub motors than a mid motor, I bought a bafang mid motor an fitted it on my carrera hellcat lmt edition 29er, Its a bad ass bike, Well happy with the build but i bought a mid motor because i read hub motors are burning out on people, Dont you bother with mid motors?, I am thinking of doing another bafang build after xmas, On a full suspension, I want too buy a CYC 3-5000w, I want the power for trails, Im going to start hitting a place called Brecon Beacons in Wales, Its almost on my doorstep, But need more power for the hills, An those CYC motors sounds amazing lol, Yeah its a big question to hub or not too hub, Or mid or not too mid, lol, Either way PEV'S, Be it E-scooters E-bikes, E-boards or E-wheels, I do want an E-Wheel is future of travel, But police here in the UK will just take it off me, Been having stress over my E-scooter, Yeah it is a 40mph monster scooter but i dont do those speeds all the time, lol, Police still dont realise if you full on throttle all the time battery wont last long, The gov in the UK have made summit that cuts out electric motors, Too stop people who use those sur-rons i think, People do there runnings on them coz they qiuck, Guess police been having issues trying to catch crims on thier sur-rons, Sad really tho coz it messes it up for legit people, When people ride crazy on these Sur-ron bikes the people who dont ride crazy gets stopped ect, So a few spoil it for the many, Typical britishness i guess, lol....
Yeah do you do the mid motors,???
anyone know the specs for planetary gear replacement 36T 47mm????
There exist two types. 38mm and 47mm dia. You have to look into your motor to see which one is needed.
i replaced my motor and the one that was sent to me had planetary gears sliding around. Do you think they forgot to send me the pin? do you think i can cannibalize the old one?
What about the sun gear? You don't check and lube that?
Any advice on planetary gear? Is metal better than the nylon ?
My bafang 500w hub motor has 1796 kilometres on it and my nylon gears looked fine. Just a clean and regrease.
I blew out my nylon gears in about 1400km. My other less powerful e-bike did 3600km and they're still pretty good. I'd say go for nylon, even though my broke, because nylon gears are cheap to replace. If metal gears wear out the hub instead of breaking like nylon gears, you'll need a new hub.
They use nylon because if they were metal and they failed it would grenade the entire motor.
Not all plastics are the same and getting a quality set of nylon gears will be better for the long term in my opinion.
How often should we open up the motor to re-grease it?
This is purely dependent on how much the e-bike is used and the time between use. If you use the e-bike seasonally, for only a few months of the summer, we'd re-grease it when you pull it out of storage and do a general tuneup as well. Bleed the brakes, oil the gears and chain, etc. If you use the e-bike all the time, then servicing every 1,000 kms is recommended. If the motor seems to get louder, grinding, or making any other odd noise, it's time to get a check-up done.

@@RizeBikes I didn't purchase the bike from yourselves, was an Amazon purchase just over 1 year ago. I was just enquiring if you had any ideas as to the cause before I tear it apart and most likely ruin it, possibly a few points to start from.
@@StonerAmongstUs I had the same issue. I noticed I'm having a hard time pedaling or throttling. It won't go reverse when try to roll it backwards
Thank you so much! My hub motor started making a clicking sound when I activate the motor on pedal assist. This saves me hundreds from watching this video.
You're welcome!
Yani dişlileri yağlamak mı lazım? Sorun nasıl çözülür. İngilizcem yok maalesef
can you put cpu cooling paste in the hub the keep it cool ?
Nope
I love your creative energy, but that is an "absolutely not" 😂
No, because the main source of overheating would be from friction since this is a spinny boi.
The motor can run perfect under its electrical load and if it is over heating there is an external issue like too much weight or dumping too many electrics into it all at once
Any idea why my electric bike wheel works when off the ground but stops when put back down?
This may happen because of old controller with bad capacitor check this first
Is it possible to upgrade an integrated 750w motor to a 1000w?
Generally yes, but you'd need to buy a new controller with the motor/wheel. This is also depending on which model as other restrictions may apply. Please email support@rizebikes.com for more info
The motors are usually very overbuilt. For example my hub is 1500w motor running at 2000w at 48v however if I had a 72v battery it would happily at 3000w
I tried to open my geared 250w motor from ancheer dx3000 removed bolts but it wont open no matter how hard i smash... i read it have some glue waterproof or something...
Hello Britka,
I suggest taking it to a shop as sometimes, the hub motor could have rust, or glue like you've mentioned, making it extremely difficult to come apart. This guide is hope to point customers in the right direction in hopes they can do it themselves before heading to a shop.
@@RizeBikes "the hub motor could have rust" now sir you got me worried 🤣 but i don't think so i think it is glue... i bought this ebike second hand it is still going great doing every day 30 miles delivery, no any weird sounds or nothing... i tried to open it because i wanted to see how it looks like inside and heard it needs greasing ...
Hi I had the same problem,even to the point some got stripped. I bought this amazing tool from Amazon called a impact screw driver. Man all I can say is ,it worked so well it even got the stripped ones out
@@Ray-nl1rh link please?
@@1squigler that tool is no joke
Kool. I think I need to replace my planetary gears. Evidently I have a choice of nylon copper or steel can you make a suggestion??💥💥🛠️🍔
Hello,
Its suggested you use whichever OEM one you had. If your motor came with nylon gears, replace them with nylon. Swapping them could cause harm and there are pros/cons between the two material so the choice of either is not as obvious as one may think.
Nylon wears better down but has much smoother/quieter operation compared to metal.
@@RizeBikes thank you 💥💥🍔
dont use metal trust me @@dogit1840
Nylon is used as a sacrificial part. Basically, if you overwork your motor, the weaker and easily replaced nylon gears break without fucking up the rest of your motor.
You forgot to show how to check the one way bearing on the middle of the planetary gear. It can sometimes seize up and not work as intended.
It can cause jerking and noisier sounding motor. Leading to a lot more motor vibration to the bike frame at certain speeds.
Thanks for pointing that out! As for testing it, it's as easy as turning it with a finger to ensure it turns smoothly or any other recommendations you think we should add here? thx
I have a seized up hub motor and there's no planetary gears in it, how do I go about breaking it free without ruining the magnets? It looks to be caked with rust between the magnet and stator. I tried using wd40 and scraping the rust out and got a ton out but still struggling lol the lady that gave me the scooter said it stopped working after her grandkids ran it threw water lol who would of thought!

Hi I've tried to find one on Amazon but there are so many , you said t20 secure . But what are the millimeters? I don't know anything about this , I want to make sure I get the right one . I appreciate your help in advance. And thanks for a great video
T20 is the actual size of the tool so no need to worry about millimeters.
@@alex-sd thank you
