Very informative tutorial on opening up the motor hub. I have a Rad Runner Plus. Aside from the basic maintenance routine I perform like checking the air pressure, tuning the brakes, and occasionally replacing the tires. I hardly dabble with the motor hub because I’m painfully aware of how much they cost to replace. That being said I typically leave that part alone and never mustered up the courage to open them up and reassemble it. I’m now at the two year mark of owning this bike and I want to give it a proper tuning session. Giving it a nice clean and adding some much needed grease. Only thing I have left to learn is understanding the wiring mechanism and hopefully one day override the speed regulator/limiter and be able to go faster.
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.
@@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.
@@ferguson8143 I would not choose steel gears. I'd rather have the plastic planetary gears wear out, than the alternative, of using steel gears that grind down something else, where you then have a different problem.
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 !
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 ❤😂.
That pin...I knew to look for it, found it, but after removal of planetary gears and clutch assembly, it would not fit back in. I tried every position this way and that, would not fit back in the trench until I took a dremel tool and reduced the edges a bit. I still can't figure out how it came out fine but it wouldn't go back in.
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!
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!
Thanks for this bro, I needed this. I've have my ebike for a few months now, I brought it used and absolutely love riding. And have been looking into maintenance and replace of it because it's my daily commuter and working on it has become a passion project for me. I very had some concerns with the motor just because the bike hasn't been used for about 2+ years before I've started using it daily. Again thank you. I love seeing videos of guys working on ebikes. Hope your doing well bro.
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
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
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
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 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!
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
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.
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!
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 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.
What grease for the planetary gears I wonder? Maybe nothing with a petroleum base as I'm wondering about any reaction with plastic? Personally I'd use fresh thread locker on the plate bolts and also some sort of non-hardening sealant between the hub plate and main body.
У меня лежит новый мотор G.063, я осматривал его и заметил клей. Потрогал ногтем и это было похоже на мягкую полоску резины-клея между крышкой и основной ступицей. Похоже это какой-то герметик с завода. А фиксатор резьбы очень сложно выкрутить, его придется нагревать до 200°С
I would not recommend hitting the axle with a hammer. Even with just moderate Force, you're going to upset the threads on the end of the axle causing a little bit of a problem putting your nut back onto the axle. What I do is use a soft piece of wood on the ground and carefully drop the complete rim and hub assembly onto the soft wood with the right Force. It will pop the HEB apart. MarkMannM2
I own a crusher xj900. I was sent the torque arms for both sides. Obviously on mine the power cord is on one side. Do I use the same method to go in and disconnect the wires and pull the torque arm into position and reinstall everything?. Thank you
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.
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
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?
I have loud rattling/grinding noises coming from my motor hub,I have found any loose spokes so it has to be inside the motor hub,my question is how long can I get away with using my bike while in it’s condition and my guess is those teeth you mentioned that need to line up when snapping the motor hub back together could be damaged on mine and that’s where the loud noise is coming from,I have the discovery ebike and the motor looks the same as the one your demonstrating,maybe slightly bigger ,I don’t know how much a new motor would cost me or if that’s the cheapest route for me to go,unfortunately my bike is my transportation at the moment so I greatly appreciate it if you could get back to me with some suggestions when you have the time,thank you.
@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?
@@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..
Metal gears will be MUCH noisier and there will be a much bigger chance of ruining the motor if failure occurs. Nylon gears are designed to be the weak point for a reason, they are easier and cheaper to replace than the entire motor.
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.
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.
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.
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 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.
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!
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...
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...
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.
*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." 💁👀👀👀*
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
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.
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.
I stripped the heads of the TT20 bolts, even though I used a brand new high quality tool and a lot of force against the bolt head. Darn! Next time I will first apply heat with a soldering iron. How can I get replacement screws? I am in the US. Would you reply with the detailed bolt specifications? Thank you.
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.
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
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
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.
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??
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.
Im thinking about going to buy some tools and take apart mine. it stoped working, and when i push the bike backwards, the weel gets stuck and don't go freely.
@@ogtech5522 Did you fix it? I have the same exact problem i am opening the bike now but a screw of the motor doesnt open. I have a ouxi in the netherlands as well Did you fix your problem en waren het dus de 3 wieltjes die kapot waren? Ik was mn woorden in het engels kwijt bedankt

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!
Is there a service interval for that particular motor? Wondering when I need to grease the gears as you've shown. Thank you.
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
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.
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.

Use a block of wood
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
I own a crusher xj900. I was sent the torque arms for both sides. Obviously on mine the power cord is on one side. Do I use the same method to go in and disconnect the wires and pull the torque arm into position and reinstall everything?. Thank you
"Don't slam it, you just want to bang it." Got it! 😂 ...this is actually a great video. Thanks!
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.
can this method work for the walmart ebike hub motors for say replacing a bearing
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
Thanks for the video it was so easy to do
Warm the bolts/screws with a small torch before you try to take them out and the lock tight will release.
Thanks for the great info
Glad the video was helpful!
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.
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.
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.
I have loud rattling/grinding noises coming from my motor hub,I have found any loose spokes so it has to be inside the motor hub,my question is how long can I get away with using my bike while in it’s condition and my guess is those teeth you mentioned that need to line up when snapping the motor hub back together could be damaged on mine and that’s where the loud noise is coming from,I have the discovery ebike and the motor looks the same as the one your demonstrating,maybe slightly bigger ,I don’t know how much a new motor would cost me or if that’s the cheapest route for me to go,unfortunately my bike is my transportation at the moment so I greatly appreciate it if you could get back to me with some suggestions when you have the time,thank you.
@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..
Hi do you have any vids on how to change the planetary gears of they are worn .
What size bolts are needed? I have a 750w hub with only screwed in 😮
Do you have a video on replacing the motor wire?
Are there different sizes for planetary gears? I have a 1500w motor.and would you recommend metal gears vs plastic ones?
Metal gears will be MUCH noisier and there will be a much bigger chance of ruining the motor if failure occurs. Nylon gears are designed to be the weak point for a reason, they are easier and cheaper to replace than the entire motor.
Thanks I need to know this stuff I got a regular commuter ebike rize not city and love it
Ty so much my dude
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.
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.
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 copy that. Thank you very much!
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
Is their a video of replacing the rear axel of an ebike
How often should this be done ?
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
That pin in the old days was called a Woodruff key that holds the planetary gears to the axel and should be replaced.?😊
What kind of grease do you put in there?
White lithium grease
@@BillBadMule123 thanks
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.
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.
Thanks for the video
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
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.
Well done!!!
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...
you say grease what grease is best. great video
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.
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
Where do I get a replacement pin? What is it called? Mine broke
What grease are you using on the gears ?
Good question! 😀
My guess is Mobil-28 aviation grease. It seems to be the go-to lubricant for this application.
@@nunyabusiness4226 i wanted to know what they use ? i've always seen people using white lithium grease with hubdrives.
Would be nice to know I hears Teflon greace ?
I’m hearing silicone grease. 🤷🏻♂️
What kind of grease?
White lithium grease
@@ryanf2782lithium grease is not ok for plastic
*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." 💁👀👀👀*
You are teacher MAN!
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
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 💥💥🍔
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.
Can i replace the motor cable? Some cut mine and i reconnected them but no succes
Same. Let me know if you find a way to replace it
Hi where can i buy a new hub motor for my mac fox
Nice job!
motor isn't spinning the wheel but spinning the axle and making the wire that comes out twist up and unplug any ideas on how to fix this?
I stripped the heads of the TT20 bolts, even though I used a brand new high quality tool and a lot of force against the bolt head. Darn! Next time I will first apply heat with a soldering iron. How can I get replacement screws? I am in the US. Would you reply with the detailed bolt specifications? Thank you.
I stripped them too. I used a Dremel to score across them so that a flat head screwdriver will remove them and put them back in.
Drill a hole in the stripped screws, then use a screw extractor
You never hit the end of the axle without a nut on it. That is basic engineering.
Why so I'm wondering. Noted but still wondering.
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.
Where can I get replacement planetary gears at?
Aliexpress. They are straight from the factories that make the BAFAN motors for e-bikes.
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
Hello, can I send my bafang motor to your workshop for repair?
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
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?
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.
Hello....you have a video change the brushes?
Its a brushless motor 😅.
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.
Im thinking about going to buy some tools and take apart mine. it stoped working, and when i push the bike backwards, the weel gets stuck and don't go freely.
