Ebike Geared Hub Motor Repair: Loud Motor & Loose Magnets (Wired Freedom/Cruiser)

This motor was loud below 15mph. This means the magnets inside were loose. Watch how to repair a powerful geared hub motor with loose magnets.

1. The small rectangular part on a shaft is a keyway not a clip. 2. The pin in the middle of the circlip pliers is to change from spreading to compressing. (Read the directions) 3. The yellowish PCB substrate (fiberglass) insulation between the armature windings and the stacktooth is for electrical insulation between them. A little bit of chipping on the exposed corner is fine. 4. DON"T USE RED LOCTITE if you ever want to take the motor apart down the road. A torch or soaking in solvent is about the only way to break Red Loctite free. 5. The biggest limiting factor of how much current you can run through the motor is the windings. If you melt the coil wire insulation, or fry a coil wire it's over for the motor. Never run more current through a motor than it is rated to handle. Glad you managed to get it going despite not doing much research into what you were doing.

[@maximumchargeEV]

GREAT comment. Thank You!

[@leoszilard3998]

Thank you for this video,The Company in Illinois referenced you when I asked if they have a video of the breakdown of the hub motor to add grease over time for preventive maintenance.I also fixed a PM motor like you did years ago with loose magnets and the only problem is that the glue can be sort of a spacer if there is too much glue behind them,So I used a starrett micrometer to measure the thickness of the magnets from the back of the disc where they are mounted to the face of the magnet and used as a reference the magnets that were not removed to see if the ones that you repaired are at the same position distance.How far the magnets seat in is critical in that the flux density lines can be a counter emf if one is further away from the outer ring they are mounted to.Since you are helping so many people with this video,I felt compelled to share some of my experiences.Good work,Someone upstairs is writing this all down.Cheers.Joe EE/P.E.

Thank you very much for the kind words! I wanted to make some useful content in case others had a similar issue. Glad it helped! I hope I never have to do this again! :D

FYI, FWIW - Since I have a Freedom arriving next week (late May 2023), I asked Wired about this via their chat. Here’s their response (other than the pending order, I have no affiliation with Wired beyond being a customer) : “Wired Ebikes On the first run of bikes that we produced, we discovered that the factory that makes the motors for us was very inconsistent in their application of glue for the magnets. Once we discovered this, we had multiple discussions with the manufacturer of the motor, and they have stood behind their motor and are giving us replacement motors for anything in our first run that fails. Furthermore, they have guaranteed us that the Current production run, which is arriving next week will not have that same issue. Any of our customers that have notified us of a motor issue, we have either repaired their motor to make it stronger than what the manufacturer would, or replaced it with a brand new motor.” Fingers crossed -

[@maximumchargeEV]

That's great to hear!

[@lagear2165]

how come that one nigga consious talk ent said they wouldnt give him a new motor? he said they made him send his old motor and then they sent back the same one to troll him lol thats messed up. i think he got the 2nd batch of motor too.

[@emaguigad]

You would think they would fix this common problem with the magnets coming loose from this particular motor. Great video! Hope I don't have to refer to this again.

[@maximumchargeEV]

Hopefully in future builds they get it right

[@Altema22]

They use nylon gears because they are quieter. The metal/nylon/metal sandwich gears are physically stronger than pure nylon, and quieter than solid metal, so they are really the best of both worlds. My bike peaks at 3,200 watts with enough torque to throw me off and flip the bike, but I've been running nylon gears for 7,000 miles with no issues so far. I do have solid metal gears, but they are so loud that I took them off the same day. The scuff marks on the magnet shell are from the factory grinding off sharp edges after balancing. Good cautions on the magnets, and if two of them snap together, they will likely crack. I lost two magnets that way. Nice job on the regluing, it looks pretty!

[@maximumchargeEV]

Thank you my friend!

[@andrewstephens2687]

Truly there is little to no evidence of the nylon gears wearing down, even when overvolting, the issue is when temps are not monitored and reaches critical softening/melting temps and you get "peanut butter gear". I bought a bike with all steel gears and would consider nylon gears an upgrade.

[@Jokersmoke106]

Thanks for the tutorial man. After watching and reading comments i think im just going to sell or run till it breaks completely. Its 3k watt motor and considerably larger then the one shown. Im sure it would get me too frustrated to repair.

[@kurtismckemmie4850]

Wow thank you so much for sharing this with us! I have a Ancheer step thru a couple days ago my hub motor started making a clicking sound when I activate the motor. The whole bike is starting to vibrate but not too rough. I will definitely try this next time it rains outside.

[@tedg.312]

If you have a shop vise the freewheel is very easy to remove. I secure the freewheel tool in the vise and drop the wheel on top. You simply turn the wheel counter clockwise like a big ol' bus steering wheel which gives you great leverage. Be sure to put some anti sieze or grease on the frewheel threads to make it easier to remove next time...

[@orvillecooper8334]

Well that is a very comprehensive video! Job well done sir!

[@maximumchargeEV]

Thanks!

[@colinwhite144]

That's a 750wat hub motor. You want to try doing that with a 2000wat hub motor the magnets would not crush your fingers it would cut them off. But there is a safe way to dreading the magnets uta a blue paper I forgot the name so when you get stater just slightly liftted you slide this paper in and you can remove by hand. I've done jobs on 2000wat 3000wat and never yes a puller just push down but not to use wheel as it will buckell. I've seen the Chinese do this in factorys and they make it look dead easy. It's conferdance if you don't have it it becomes really hard it's amazing when you no the trick it becomes easy but still watch your fingers. Even a 750wat not be taken lightly as the guy who made video. These videos are good for people who haven't tried jobs like this

[@Jokersmoke106]

I have 3000w... and it's slipping under weight. I think I'm just gonna ride it until it goes. That or sell for a fraction of the cost

[@davidlorin1379]

Hey, I didn't know Jeff Goldbloom narrated E-bike geared hub motor repair videos. I hope you just went ahead and re-glued all of the magnets.

[@boosted.]

I sure hoped you marked the magnets this side up so the polarity is correct.

[@maximumchargeEV]

I sure did!

[@merseyian]

I tried metal gears, they stressed my motor. Stick with nylon and replace them when you strip them from over torquing your motor when starting on a hill etc.

[@maximumchargeEV]

full metal gears?

[@MrMtr999]

Great video! I think i start to having the same sound like in this video, but if i don’t throttle but cranking out instead, the sound will not occur. It is design flaw or bad preparation from factory for sure. It doesn’t look too difficult to reglue those with epoxy. Thanks again

[@maximumchargeEV]

Good luck man! I know you have one of the first batches of wired bikes out there too. Wasn't too bad to fix this.

Hello sir maybe you can make magnet ring😊😅

[@maximumchargeEV]

what do you mean?

[@colinwhite144]

Is that a 750wat hub motor and how many magnets do 750wat motor have is for setting sw900 display. And are all 750wat hub motor the same inside. Best tip to stick magnet is liquid nails it's for wood and metal. You put a fine scraping on both serface and it works I done this a 2000wat motor 3yrs ago d still going strong yes magnets on 750wat hub motor thanks

[@spencer4757]

Is this still holding up for you? I just re-did this to my bike with JBWeld after my 1st application with another adhesive failed.

[@maximumchargeEV]

I actually partially burnt that motor up (hall sensor wire desoldered itself) but the magnets held up!

[@Edricofifrit]

That sounds like the clutch is slipping too

[@maximumchargeEV]

Clutch was fine, just the magnets.

[@zeljkomrksic9687]

I think i have the same problem on my E.T. Cycle F720. I put more grease on the gears, and the noise is still there at takeoff. After seeing this and hearing your noise, I think I have the same issue. My bike is only 3 months old.

[@maximumchargeEV]

Well now you know what might be broken. Good luck!

[@andrewstephens2687]

Great vid I need to do this to at least one maybe 2 motors. I want to go ahead and reglue all the magnets, any tips for removing the ones that may be glued well already? Would a normal heat gun be hot enough?

[@maximumchargeEV]

I would try to pry something very thin and flat behind the magnets, like a thin putty knife. Work at it slowly.

[@nisstw]

Do not use heat gun. Over heat can damage magnet.

[@colinwhite144]

Some magnet they don't use glue the magnet it's self ke in place because it's a magnet. The poles will be the same that's what keeps them in place if you do put glue on be sure to keep your magnet the way up as you mix the poles up and that will make your motor go slower strange but true I used to assemble these motor. If these magnets have no glue on do you find that strange on all magnets that shoud tell you not to put glue on

So far so good!

Probably a dumb question, but would you recommend this bike? I've been stuck between this one and the Ariel Kepler. This one would have won me over but seeing this issue and the fact that the owner of the company isn't really helping people with this issue it's making me lean more towards the Ariel. I am able to work with tools and engines, but this just seems like a pain to have to deal with. lol.

I would recommend this bike yes. I believe this issue was fixed, and the owner offers to replace the core of the motor for free.

@Robert Haworth thank you my friend!

[@geedub7912]

Actually, leaving the surface somewhat rough makes for a better gluing surface than that of a fine surface as it gives the glue something more to grab on to. Imagine climbing a vertical wall: if your fingers can find a crevice then you could cling tighter than you could if the area was smooth with nothing to hang on to. J-B WELD is best applied to clean, dry and somewhat rough surfaces. Sometimes, on certain applications, extra holes are drilled so the glue can get an even better foothold.

Are the magnets being held in place behind that little aluminum ring they seem to be set down inside of

[@maximumchargeEV]

They are held on by the housing of the motor, the glue, and the pressure of them pressed up against one another. They also are pressed outwards into the housing at speeds above 15mph due to centrifugal forces.

OMG man, learn terminology and how to use tools. The snap ring pliers can be changed from pinch to pull by moving the pivot point. The little piece you called a "clip" is a key. Another point is the freewheel sprockets only receive power from your legs, not the motor. So no matter how powerful the motor it will have no effect on the wear of the freewheel when you are working with a hub motor system.

[@maximumchargeEV]

I noticed I could switch the c clip pliers after haha. Rookie mistake. Still learning. I'm aware of the freewheel mechanics with the hub motor, just wanted a better feeling gearing.

[@bsmirz]

Less talking more repair !!

[@maximumchargeEV]

Sorry

[@fraaggl]

8:35 so it's better to have weak parts so they can break before the main part does... That is such a modern BS engineer thing to say. This doesn't consider that 90% of the people will simply throw away their motor or most certainly entire bike just because one of the planetary gears have ONE teeth broken... This is just a PURE SHAME and I really really hope that it will stop as soon as possible. The most majority of trashed hardware comes from this train of thought : let's just take a practical and sturdy equipment and replace some of the part with plastic or other weak material ! But it's for your own safety of course people, not for money NOOOOOOOOO of course not !!

@@maximumchargeEVI'm quite surprised that you admit your mistake ! I was a little bit rough on the edge with my comment. But this modern "philosophy" is enraging. The fact thatEVERYTHING you buy today will let you down for a 0.10 € part is just a pure shame and almost no government are taking action. A little law against planned obsolescence here and there but just for a very small part of the industry is not enough. Our landfill are overflowing with trash that could be working fine. I hate that.

Yo under 500 miles my wicked cruiser started making this noise.

[@maximumchargeEV]

Seems to be a major manufacturing defect of that motor

[@CONSCIOUS_TALK_ENT.]

@@maximumchargeEV Damn man.

[@CONSCIOUS_TALK_ENT.]

@@maximumchargeEV Did you fix yours?

[@maximumchargeEV]

@CONSCIOUS_TALK_ENT. yes this video fixed it.

[@paulstrollo3187]

be careful selecting products, some JB Welds will conduct and you don't want that...

[@maximumchargeEV]

Which ones are conductive? This one is an electrical insulator.

[@paulstrollo3187]

i can tell you for sure jb weld stick is conductive i suspect a few others but not tested.@@maximumchargeEV

[@pavlovauk9162]

But yiu didn't show exactly how you doing everything, how you putthethigs back in. I don't believe you managed to use the gears puller and plastic crate, to remove the planetary gears etc That's BS.

[@maximumchargeEV]

Not sure what to say man. I can't film holding a camera whole working with my two hands.

[@PtolemyCeasar]

Looks like hell, sealing off those hubs is a better way to go.

[@maximumchargeEV]

It was tedious for sure

[@Busdathead]

What no one tells you is once you change freewheels you will probably have to buy a bigger chain because it will not shift correctly anymore .

[@maximumchargeEV]

This freewheel was fine with the original chain, but just barely. I did upgrade the front chainring to a 60 tooth and THAT definitely required a bigger chain

[@EBikeBuilder_]

When you change free wheel to a larger one, it will require longer chain, also might need to change the chain ring if its worn. If Drive train components don’t wear evenly, you can get chain skips and other issues

[@Zetler]

Holyshit. It’s easier to buy a new bike.

[@maximumchargeEV]

Eh it wasn't that bad. It depends on how mechanically inclined you are to fixing things. I've worked on cars before so this was easy.

[@kurtismckemmie4850]

Looks way cheaper watching this video than buying a new electric bike. $$$$
