How to Open an Ebike Hub Motor 

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 !

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!

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.

Put the nut on that axle before hitting it. You are damaging the threads. Every mechanic SHOULD know this.

Thank you sir. Clear explanation on how to. Hope more videos are coming.

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!

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

Thanks for the video! Your instructions worked great for a Ride1Up 700 w/ a Shengzi hub motor.

You never hit the end of the axle without a nut on it. That is basic engineering.

This dude makes honor to the brand! Very good quality content and production :)

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

just the vid i was looking for,cheers

This helped out a lot thanks for the tips great video

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

Great video. Thanks

"Don't slam it, you just want to bang it." Got it! 😂 ...this is actually a great video. Thanks!

Thanks for the great info

Thanks for this.

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.

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

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

Thanks I need to know this stuff I got a regular commuter ebike rize not city and love it

Well done!!!

Nice job!

Thank you for this video. You helped me to realize the 🔑 was super important.

Do you have a video on how to rewire the inside of the hub whereafter the group of wires get ripped out?

Ty so much my dude

Thank you so much , do you have any video teaching how to Change the shock absorber ?

Do you have a video on replacing the motor wire?

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

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!!

can this method work for the walmart ebike hub motors for say replacing a bearing

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.

What size bolts are needed? I have a 750w hub with only screwed in 😮

Thank you ,

Thank you for this video. Do most stock fresh from companies e-bikes come well greased?

Can i replace the motor cable? Some cut mine and i reconnected them but no succes

You are teacher MAN!

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

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!

I have hyperscramble 2 like to buy 20x4. 25 rear hub motor with wheels, where can buy this online?

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.

Very good video, from your experience, should there be some humming noise from the gears when the bike is on a stand. TIA

How frequently is a good idea to open the hub motor and put grease in it at the planetary gears?

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

Hi do you have any vids on how to change the planetary gears of they are worn .

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 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?

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.

Hi thanks for the great video, can you please tell me the size of the 6 bolts , thank you

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

Is there a recommended torque value for the bolts to the motor housing (the "locktighted" ones)? Nm please.

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?

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.

Any ideas how to get a better motor for a TopGuard fat tire e-bike. The cable coming out of the hub twists and breaks itself and messes up the controller. Won't go! Any ideas for a new motor with better wiring for the 26" fat tire bike?

What type of grease and brand do you use for hub gears?

I wonder where you get that special torque set

Is it recommended to use locktight when putting bolts back?

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)

How often should this be 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...

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 👑

*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." 💁👀👀👀*

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

What about applying some more locktite to the six bolts so they don't come loose?

@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?

I wouldn't be hitting the Axel like that that's for sure 😭 UK 💋👍

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?

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.

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

What is the torque when reinstalling hub bolts? Or does it matter?

Hi could you tell me where I get the t20 wrench and it's full type, cheers, appreciated

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?

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 👑

Any idea why my electric bike wheel works when off the ground but stops when put back down?

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.

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

Any advice on planetary gear? Is metal better than the nylon ?

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

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.

Any issues going to metal planetary gears, besides the noise?

can anyone give me spec on the wheel he is working on thats the kind i want for a project

Its called a woodruff KEY

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.

My hub motor is stiff, completely locked one day, was a hassle getting it to spin again, but ever since when I pedal or use throttle bike does go but when I stop the bike stops- no free-wheeling.

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??

How often should we open up the motor to re-grease it?

T 20 size or the screws size please thank you

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,???

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??💥💥🛠️🍔

can you put cpu cooling paste in the hub the keep it cool ?

On 3:03what would be the right proces to putting the locking pin back do i just push it in with my fingers??

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.

Is it possible to upgrade an integrated 750w motor to a 1000w?

anyone know the specs for planetary gear replacement 36T 47mm????

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.

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

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...
