Sweet! Just ordered a Turbo Levo 3d gen, and very happy to know there are avenues to fix these common problems after warranty. Thanks for the video! Very confidence inspiring! Future Customer here lol
What a great attitude about this!! thank you for the feedback. I totally agree and frequently find myself talking people down from various frustrations about having to repair motors at all. So, i't refreshing when we see people who understand things break and then glad when there are service options available! Have a great day, enjoy the new ride, and feel free to reach out any time for troubleshooting or problems. 😁😉
We have discussed this many times here in the shop. The big question “why not?“ We kind of make a joke that perhaps a seal will produce just enough drag to reduce the battery life by about 0.02 seconds and God forbid a published charge time not be a few milliseconds better than the next competitor battery life. 🤣🤣🤣
Aloha. Thanks for the great info. I've worked on many kinds of gearboxes and sophisticated drive units over the years. And often, yes, having the right tools is the difference between success and failure.
It’s so amazing how much of a difference it makes. In the early days we were using a lot of home made rigs. Once we had tools manufactured for specific purposes it was a game changer. You couldn’t pay me to go back.
Awesome to have found you guys on UA-cam. My Levo motor is doing fine, but it’s nice to know you guys provide this service if/when I need my Brose motor serviced. Cheers.
@@ebikemotorrepair I was googling for hours yesterday, looking for any tech support for a JauoPay and I never found a thing nut Amazon links. something inside is hanging up like the brakes are applied when when letting off the throttle. I took the case bolts out, when trying to get the side plates off the motor freed up and I can spin the axel with fingers now. Do you know a good resource for help with hub motors?
Excellent explanations. Thank you. I heard a crunching noise from my motor yesterday while riding the muddy trails. After washing the bike today the noise if not there in my street test ride. Any ideas?
It’s hard to say for sure, but you may not actually have a noise. Sometimes noises can be tricky to trace down the source. Most likely if you had a noise that would. But again, without having eyes on, it might be a little tricky to troubleshoot. If the noise comes back and is consistent, then you could consider shipping it to us for an inspection. But considering your problem went away after you watched it from what I understand, that sounds like something was just noisy outside of the motor.
Hi.. Great video. Are all these issues also present on the 2.2 motors from the 2023 Specialized turbo levo line up? Also, comparing Brose, Bosch and Shimano, which are the best motors in your opinion?
I get asked this a lot. So far, I must say they all have pros and cons. I tend to persuade people to buy the bike first and consider the motor second of the ones you asked about Shimano is my least favorite since it’s almost impossible to service them once they’re out of warranty. Speaking purely as a rider I have no fundamental performance complaints about the Shimano. speaking as a mechanic…. I wanna throw them all in the trash lol
Yes please, I've just had the clicking sounds, thought it was small stones hitting the frame, but at the same time the power was intermittent . Have you heard of this?, also when blasting over roots or rock gardens sometimes the motor jumps into recline then back into turbo😢
It might be something else altogether. Sometimes problems will manifest and it can be easy to assume it is something like what you suggested. however it might be the clutch bearing in the drive pulley going bad or bad already. You should send it to us for inspection. We can see what is going on with the motor. Also, it is possible you have several things occurring. Repairing the health of the motor will help diagnose other potential problems outside the motor. These are usually fairly easy to diagnose once the motor is fixed. But I will be willing to bet everything will get back to working order once repaired. Please use the service ticket on our site before sending us anything .Thanks for reaching out. ebikemotorrepair.com/repair-overhaul-service/?v=7516fd43adaa
Was chatting to my local bike shop and they were working on a specialized ebike. Had to send the motor off although it was derestricted specialized still honoured the warranty, purely on the basic that they know the belt still fails regardless if it has or hasn't been derestricted
@@fractalofgod6324 ok but hub motors fail just as frequently and are not easily repaired due to most manufacturers don’t even offer support of any kind. Plus in many cases to change bearings you have to remove the hub from the rim. This is a lot of work. I’m not a huge fan of hub motors for the use in mountain bikes or serious commuter or road bikes. If you’re just putting around a beach town or golf community then hub motors are great.
Awesome video! You answered to a lot of questions I didn't even know I've had! But I'm still wondering why this motor even needs planetary gearset? It seems like it is the only thing that is unfixable. Why they did not just put that gear straight on the motor shaft?
Im no engineer but I have my moments. I would say it is there for support. In most internal motors the drive spindle is quite close to the internal motor. The drive spindle in the brose is a significant off set distance away from the internal motor. Like by nearly 2 inches. Make sense?
On average around 3000mi. But it’s subjective. Riding conditions, rider weight, drive train, how hard it’s ridden, and other factors can effect the life. Like anything with a performance motor the harder you push the more likely something will break. There’s also the chances for small manufacturing defects to pop up and cause early death. But most customers get about 3000mi. One guy got nearly 12,000mi on a factory brose!! 😳 That’s unheard of frankly. But still. Pretty cool.
@@ThePiggly_Wigglys yeah most are under warranty still. But we have seen a few already with customers who don’t want to bother with warranty wait. Although we always advise not voiding the factory warranty. I mean free is hard to beat even if it means a little more waiting.
They first started being used as electric power steering motors, then converted to ebike use, I have one & I work on them in our fleet of rental bikes.
How much larger does the ebike market have to get before ebike motors start getting designed from scratch for bike use and then adapted for power steering retrofits?
Really nice video thnx , yes I did take the electronic cover back off ( there was a lot of water in there for some reason ) and put it back on and it worked just fine including the torque sensor. I have a picture from it
would you know what's wrong with it, if you only hear grinding noise from the motor when you on the higher gear? meaning when going uphill, the motor start making the grinding noise.
@@RonA-s1g these kinds of noises, believe it or not can be quite tricky to figure out without tearing into the motor. And sometimes we find that it’s not the motor at all. You should try riding with the motor off and see if you can still get the sound to occur. it doesn’t rule the motor out completely if you still hear the sound, but it sure does begin to pinpoint the only possible culprit in the motor. Also, this would highlight a lot of other culprit outside of the motor. Such as pedals, crank arms, chain, rear, cassette, etc.
This is fabulous!! Thank you !! I have a motor that has difficulty disengaging assist but can be disengaged pedaling slightly backward. Thoughts? Torque sensor? Sprague Clutch? Brose 2.1 Motor , Thanks !
Great video, thanks. In you biz card at the end, I see the listed 5 motor makers. Do you also repair Shimano, Specialized, and Bafang motors? Thanks again.
Not sure how we missed this comment. but to answer your question specialized motors are all either SL or Brose. We service both. We have a kit for both bafang mid drive and shimano line-up. But both bafang and simian are not motors we offer service for. The bafang are so cheap usually to pay us to repair them you are almost at the cost to replace it. The shimano motors are too tricky as they have booby traps that can sense if the motor has been opened which will make the motor fail completely.
You got it my friend. We are currently doing one on Bosch. As it is a much more popular motor than the Yamaha and some of the other motors. But we will add the whole yammy legacy to our what’s wrong series thanks to you!! Meanwhile just for you… Yams are really simple. The most common thing we see is simply sloppy drive assembly bearings. Mainly left and right. Then we also see the drive gear (small nylon gear that transfers power from internal motor to the drive assembly) can break off teeth during sudden change in load. Also inside that gear is a small clutch bearing. If the gear starts to crack near the center it can allow the clutch bearing to slip inside the gear working against its its purpose. Lastly, there’s a common “torque sensor error code” that actually spells game over. The motherboard is to blame. It’s a fault that prevents the motherboard from actually seeing the torque sensor. So it won’t see a new sensor either. And the unfortunate part is a motherboard is keyed into the exact magnetic field of its own internal motor magnet at the point that f manufacturing. Meaning the motherboard isn’t something we can “swap” if it’s faulty. Replacement time in that case. Can’t say we have seen much more on the yams. But we love the freaky things so let me know if you hear any good odd stories.
4000 miles on my levo and it is the funnest damn toy I have ever had in my life. I also delimited it so I can pedal thing up to 33 miles an hour! Never a single problem. And I ride it hard and beat it up. But I admit you'll probably be hearing from me pretty soon. 😆
yeah you are at about that point. Send it on over when you are ready!! thanks for the positive post! I feel the same way. Fun toys eventually break. Not a good enough reason for me not to own one!! LOL
@@ebikemotorrepair Well it was time. I sent my motor to you and you guys did a great job! Absolutely fair pricing and pretty damn fast turnaround. Everything went smooth and the motor is working beautifully. I always recommend you guys to my friends! Thank you!
Hello there from the Netherlands. Maybe you can advice me on this one: Yesterday evening I tried to launch the light and on the display it gives a error code 0x91. I found on the internet that the Fuxon light on my Bulls Lacuba EVO Lite 5F causes the problem. Can you advice me ho to solve it? Best Regards Hans
Yes, totally normal. The side case cover that you took off to reveal the belt actually holds one side of the magnet spindle. The front drive, spindle and magnets are all run unit. So when you remove the cover the magnets drawn together with the copper slap against the wiring on the inside.
I have a Gen 3 and just had a slipping issue @ 2000 miles. I actually thought some of the teeth on the belt stripped out until I saw this video. Also, I cannot believe that these motors aren’t sealed from the factory. I had no idea that water could just go in the motor so easily.
You likely need a new set of clutch bearings. The belts don’t “slip”. When they fail they go pretty much completely. You should send it in for inspection and we can let you know pricing options.
if they let you keep the old one we buy salvage motors. Sometimes they don't ask for them back from the shops. If your shop have any they want to unload we buy them sight unseen. @@TheAngryHusky
Great video, thanks! In your opinion, based on the quality of the design and components used, and taking into account the number of repairs you do on the Brose, how does it compare to the Bosch? Ordered a Levo with a Brose 2.2 motor but hearing lots of horror stories, mostly on the older Brose 2.1 to be fair, but wondering if I should find a Bosch CX gen 4 powered bike instead. Appreciate any insights you have - thanks!
We definitely repair more brose than Bosch but I suspect it’s because there’s simply more of them in the US. I’ve been trying to find some metrics to see if the ratios of failure are similar based on how many units there are. I suspect issues will have a similar statistic across all the motor manufacturers. But they all have different kinds of stuff go wrong. So it’s hard to say.
@@chetanrazvan3896 its noisy is the only down side , like an RC car from 1990 , but cant fault that 18k for sure , i had a felt 9E20 and the bosch was a great motor for sure
In my 2018 Fantic Integra 180 w Brose gen 1 alut motor there is one odd feature. After 5 to 10 minutes intense riding with boost power setting it a bit looses power and isn't cinsistant with power delivery within one crank circle. And always when I then do a couple of cracking circles backwards, the motor immediately starts delivering boost power as it should. Has anybody experienced similar and maybe found what wrong? What do you Bike Motor Repair guys think about that?
@@karraite that is actually odd behavior. It is possible that you could have either a power delivery issue such as a connection, plug or socket or even wire harness that is faulty or damaged. Your battery could be going bad. There are also some clutch bearings in those units which can begin to slip. However, the backwards rotation fixing your problem, is a bit mysterious to me. When you have the intermittent power, are you seeing any error codes?
thanks for all the tips, trying to asses if it is worth replacing my belt and bearings on a 2017 Sp Vado. I am experiencing so issues on the drive side. it is incredibly stiff to turn the planetary gears even thou it all looks clean and good. I guess the bearing behind the gears is gone. does this make it scrap? Thanks for the video!
@@oliverbruchhauser9342 in almost every case we have an option to service the motor for less than replacement cost. Definitely worth sending it to us. We don’t charge to inspect.
Hey man, interesting video.. I'm waiting delivery of a new levo with the 2.2 motor. Live in the north of Scotland so it gets pretty wet here. I'm thinking about running a bead of silicone grease around the water ingress points you mentioned behind the crank arms. Do you think this is worth doing? Thanks in advance for any advice : )
Definitely DO NOT do that. That gap is Actually 2 independently moving parts. It needs a proper crank seal as what comes with our kits. but installing it would void a warranty. Alternatively you could swipe some marine grease in there but it isn't a permanent solution at all. but it will certainly help a little. I would ride the warranty out before modifying or upgrading. when its time you should check out our partner in UK they are awesome!! www.ebikemotorcentre.com if you reach out to them be sure to tell them we sent you!!! thanks
@@ebikemotorrepair I’ll give them a call, hopefully the x-rings are available to order?! Yeah, I meant a silicone based grease, not a sealant so yeah marine grease could be a good shout. It’s gotta be better than an open void
@@andydtkd ahh I totally missed that in your original comment. Sorry. But yes something is better than nothing. Once out of warranty send it to our partner in UK to seal it properly. You won’t regret it.
Great video! What is the best greas for the planetary gears to be the most silent? I tried a lot of type, but the most quite is the original, just i do not know what that could be.
Usually don’t need to grease them. If they’re making noise it’s likely the beginning of the bearings failing in them. Unfortunately when they go it’s time to replace. But to answer your question we use a MOLYKOTE PG-75 Here’s a link to it on our store page: ebikemotorrepair.com/product/gear-grease-for-ebike-motors/
I am looking at a Vado bike, but these motors seem to have several failure points that could be easily addressed by Brose themselves. Here in the UK it would cost £200 to make the Brose motor watertight and stronger, seems daft that I must spend another 200 on an already expensive bike. What is the best manufacturer of midmotors?
Just bought a kenevo... is it a good idea to send it to yall when new to get those seals put in? Would that void my Warrenty? Or should I wait until the warranty is run out?
Hi @ebikemotorrepair, which parts do you recommend for Brose T in order for seal it preventively? Would those x-rings be enough? Also do you ship to Poland? :)
we have a partner list here so find the closest to you and work with them. Also there are several additional things you need to completely seal the motor. where to buy: www.ebikemotorcentre.com/where-to-buy/ also here is a link to our partner's upgrade video: ua-cam.com/video/-dyTMOqVNto/v-deo.htmlsi=LKCmKNo-CkEwFpZD

Do you know of anyone in Australia that does comparable work to yourselves..or is there anyone in Oz reading this that can put me onto someone here doing comparable work, with upgrades and seals..?? I don’t use the app with my bike, so have no idea how many miles..but it’s a lot..! I often ride remote, and would hate to get stuck due to lack of maintenance…
We actually have a partner in Australia. Check them out. Definitely let them know I got you guys in touch. PureSports 6 Cheshire Grove ELANORA Qld, 4221 Australia Tel: 07-55339289 paul@familymoir.com
Looks like a complete under engineered piece of junk. Unfit for purpose comes to mind. If that kind of build quality or lack of was fitted in cars etc there would be a law suit against the manufacturer. I think quality like that is totally unacceptable ! Where are they made?
They are made in Germany actually. And yeah that would be quite unacceptable type of treatment if this were in the automotive world. Although in my opinion one of the biggest problems with the Bros motor is in fact that it’s over engineered. They were trying to keep the weight down the power high and the noise low. The Bros has more moving parts than any other motor that we service. Classic German engineering. Super complicated and high-performance for some amount of time at least. Until it breaks. 🤣
Any ideas what went wrong? What the problem might be?? my turbo Levo is 1.5-year-old, I was cranking up a hill, then my motor made a high-pitched free-spinning sound and the pedals & cranks would not engage the motor but just spun without moving the bike. I turned the power off, coasted down the hill. turned the motor on, it worked for a few minutes then repeated the same symptoms, i turn power off and got off and waited a minute and turned power on and started pedaling back. still 5 miles away from parking lot i kept repeating the off on thing until i could build enough forward momentum to coast back. load the bike I went home about 30 min drive. at home, i had to see if the problem still was there. turned it on, rode around my half acre yard, it was working fine so i kept doing laps, harder and harder but it wasn't failing. i don't have any hills in my yard, but i tried to crank harder and harder and after about 15 minutes it finally failed the same way again. on my specialized app i did a diagnosis and it pulled and error code: SL1-B-HS-256
you likely have a failed belt pulley clutch bearing. I would strongly recommend sending it to us for inspection. We dont charge to inspect and will gladly take a look at it for you. be sure you fill out a service ticket before sending anything our way. ebikemotorrepair.com/repair-overhaul-service/?v=7516fd43adaa
Hello nice movie...but is the brose s engine the same engine if it 45kmt and 25kmt...I ask because my 45kmt is done...I have a offer on a 25kmt.they look the same? Best regards Brian
Thanks for the comment and for watching. So, those motors are mechanically the same but obviously programmed differently. Each motor needs to be programmed specific to its bike. There are all kinds of things the motor need to know to operate properly or at all in some cases. I would advise for brose working with your bike shop for a replacement rather than buying second hand. However we buy old motors for salvage.
@@ZRome187 hi there. Thanks for your comment. We can definitely help you fix the problem. However, belts don’t slip. When they break, they fail catastrophically. Usually slipping is a result of a failing clutch bearing inside the belt pulley. I bet you are due for an overhaul. If you will visit our website and fill out the service ticket form and send your motor on it. Also feel free to reach out for any questions through our website. EBikemotorrepair.com.
My pleasure! We hope to make more. I don’t fancy myself a UA-cam star but if you or any of your riding buddies have anything else of interest be sure to let me know. Will will try to build some contents around it.
Добрый день! Подскажите, у меня мотор Brose Drive C при включении поддержки для подъема велосипеда по ступенькам велосипед отказывается ехать вверх, при том что по ровной поверхности он едет, а в верх просто как будто ему не хватает мощности? При этом уровни поддержки при работе педалями работают исправно.
we haven't made a similar video on bosch yet. But we can certainly discuss it. Feel free to connect on our website form or we can try and connect on the phone.
Yeah, I would be very interested in your experience with Bosch, because I knew that Brose and Shimano had some issues but thought Bosch was better, but recently learned about some bad designed seals around the crank on the 2nd and even on 4th gen. I rode Bosch 1st gen for almost 15000 Km and without any issue, so I´m a bit surprised about these issues on newer motors.
@@stanolaukoSame here, I have Bosch 1st gen, big metal engine, no failures. Now I want a new emtb with full suspension and I am a bit worried about the reliability of new motors
After my Turbo Levo stalled, I was able to pedal home and it was hard to turn. And I found that the bike does not roll backwards, does not go backwards. I disassembled the Brose motor and saw a belt without teeth and the planetary mechanism cannot be turned by hand. Please tell me this is the end of the planetary electric motor?
No don't panic. the spindle of the internal motor is held in place by the side case cover (also that small grey spindle is the same part of the internal magnets). when the side case is off it allows the magnets to attract to the side of the internal motor preventing it from spinning freely. You likely need only a belt. However if you send it to us for inspection we can take a look at the rest of the motor for you. We dont charge to inspect.
@@ebikemotorrepair I reassembled the Brose electric motor without a belt (it is impossible to buy it from us), changed the overrunning clutches, turned on the pedestrian mode with the button on the steering wheel, the motor worked for a few seconds and turned off, I did not release the button. The battery is in good condition. What is this? Why did the motor turn off? Maybe the firmware of the motor has flown?
@@СашаПетров.Жизнь I believe it is simply detecting something is wrong internally and self shutting down. Please clarify, you mentioned belts are impossible to find. the way it reads is from the US? we sell them. Unless you mean something else? Where are you located? We have worldwide partners.
Hi, i have a 2.2 which stopped working only 10 hrs after having the speed limiter removed via plug in system. I have been told it might be the torque sensor ??? is this something that can be repaired ??
we can repair them yes. If that is in fact what is going on. But we are wizards at troubleshooting. if you want to send it to us for inspection please see our site to fill out a service ticket.
What do you recommend that a new Levo owner do to protect their Brose motor from water? Your adding an oilseal outboard of needle roller seems like a no-brainer ( why don't they do this at factory???) but may void warranty. So what would you do if you bought a new Brose bike?
So I’m a big believer in warranty support. If somethings under warranty and it breaks let it break. You could put a little grease down in that gap between the shaft and the sprocket carrier and that will certainly not void your warranty. At least I would be very surprised if it would. You could also put the X ring on the left side Between the case and the crank arm. That certainly won’t void your warranty. While this isn’t bulletproof it should aid in preventing bad dust and water ingress into the unit. Otherwise I would play the odds and just fix a motor when it starts giving symptoms once it’s outside of warranty and then fortify the motor at that time.
@@ebikemotorrepair Thanks. I suspect most people agree with you but for me it seems quite insane that Brose do not install that ($1?) oil seal at the factory knowing that water will get in and start corrosion from the first wash of the bike. Sure it may take a couple of years to do serious damage but why even allow it to happen at all? Warranty replacement is great (for 2 years) but then what. I would prefer a motor that does not need replacement because it got wet - e.g. every EV car motor in the world!
sounds like the speed sensor. Either you have it plugged in wrong, the magnet has shifted, or the wire is damaged. But this is how it behaves when the motor is unable to get info from the wheel sensor assembly.
At 18:20, you say the motor knows specifications related to crank arm length, wheel base, etc. My Turbo Levo Comp came with 165mm cranks. I have since replaced the cranks with 150mm. Am I hurting the performance of the motor? Thankfully, I haven't had a problem yet. Even while running unrestricted.
It certainly doesn’t hurt the motor, but it may not perform as good as it could. I’m not exactly sure which way the power map would be affected by a shorter crank arm length I would have to think deeper about it but what would occur is power delivery difference. A shorter crank arm length will produce less torque on the torque sensor. So knowing that length is how the system compensates for power delivery.
Great Video! I just changed the belt on my drive smag engine and unfortunately removed the cover from the electronic side, the pins to the torque sensor are still straight but i get engine internal error , try to think about a workaround to check it without removing the drivetrain
We remove the drive shaft assembly to make sure it’s correct. Honestly you should send it to us for that. We can inspect the rest of the motor for you too.
My specialized brose 2.1 engine, after replacing the belt and freewheels, began to spin for more than 200 milliseconds. What could I have assembled incorrectly?
You can buy from us but we strongly encourage you to send it in for service. We have tons of experience and tools and can likely help you avoid causing other issues. Go to ebikemotorrepair.com and contact us there with your questions and symptoms. We can usually help troubleshoot but please consider sending it in. We don’t charge to inspect.
so... i was biking, vado 4.0 - light turned yellow so i let off, down shifted, and felt it go... lost all drive and terrible noise. then nothing. just got the motor apart. turns out the planetary gear set is destroyed. id like to pull it further apart but i dont have small enough tools. i rebuild engines and transmissions at home but for diesel trucks. not this small stuff.
Great review thanks! I read a lot about the noise problem with Brose 2.2. There are a lot of complaints about very heavy noise from the motors. Some people experience it with the new bikes, and some have the issue after some period. What can be the reason for that?
That’s a great observation you make. We have seen it as well. Some of our customers say they’re on their fifth or sixth warranty within a few months of some of the newest bikes. We haven’t gotten any official response from anyone official within Brose. But, we speculate they must have made some changes within that model range the internal motor that could potentially cause the planetary gears to put unwanted stress on the bearings that support the magnets. Again this is pure speculation not an official diagnosis. But something seems different for sure. Mostly in brose noise occurs when the bearing stack inside the front drive spindle starts to loosen inside the front drive spindle itself. I can make a video about this once we have enough statistics to go on. Until then it’s smart guess work.
New turbo levo comp carbon Nov 2022, I got one for me and one for my wife and hers is quit and mine if very loud after 20min or riding. Bike is in shop now and hope it will be covered but more so that the problem has been fixed. So if specialized dose not find a fix for the 2.2 motor and you do please post or let me know as I would pay to have a quite motor for sure. It is very sad that I now want to sell the levo and go with a different brand. you would think after all the problems with 2.1 the new 2.2 would be rock solid.
@@843raptor yeah some are louder than others too. Not a lot that can be done about it from a mechanical side. It's due to nuances in manufacturing as far as we can tell.
Just wondering, no matter what the motor is sent in for or whatever the issue is, do you always do all this other preventive maintenance that you’re showing in the video?
it just depends on each person's unique needs. Some people are on a budget and we can have a fix-whats-broke mentality. Others want a middle road option and some want the top shelf service. But we dont charge to inspect and will give you our recommendations ahead of time after we take a look at it.
@ebikemotorrepair - question for you - I have a 2022 levo and the motor works fine, however, it get very loud when it gets hot. After about 30 mins of riding its so loud you can hear me coming a hundred yards away. Does this mean my motor is going to fail soon or is this normal in the newer motors? Thanks!
we have seen this occur on some of the newest bikes. Not 100% sure the cause just yet and it is possible it is just a noise motor. It is also possible you are hearing the early stages of the planetary gears beginning to fail. but it's really hard to tell for me without inspecting it. Ride the warranty out and once out of warranty if you are still having th problem send it to us for service. we should be able to figure it out for you.
Question for you. I have a BH ADAM. X. WHEN I PEDDLE I hear a noise and it seemed to bind and and hold the chain to it would bind. When it's off it peddles normally. Any suggestions would be appreciated.
My 2021 Turbo Levo motor is making a noise like a spoon hitting a tin plate on every crank revolution. It immediately stops for a little while when I back peddle 1/4 turn. About 5 minutes later it starts again. Any idea what's wrong?
Wow! I thought Bosch was garbage. Maybe it’s a light weight competition thing. I got a rocky cause I like a mechanical diesel with torque that rolls coal, lasts forever, is more efficient, and easy to work on.
If you care to share your thoughts and experiences on Rocky Mountain please feel free. It’s such an uncommon motor we have had zero requests for services over the years. But we have dissected them. Feel free to email service@evikemotorrepair.com
I have a brand new Rockrider Decathlon with a brose C, to remove the 25km/h limit i have moved the sensor to the pedal and placed a magnet under the pedal arm but after 3-4 km the power cuts off and i need to restart the display on the bike to work again, can you provide me with a solution please? I did the same on my old Brose T motor and no cutt of problems just ERRORS from time to time.
yeah they are really trying to crack down on things like this and they can tell when its been tampered with so the solution is to leave it at a factory setting. I do know there are people who make chips that can over ride and make them faster but I am not familiar with the options also we have to stick to certain standard compliances with federal regulations so officially we don't get involved with modifying speed or power outputs.
Do the Giant syncdrives have any modifications, mechanical or software over the Yamaha motor it’s based on that limits repairability? Are the pwx3 less reliable than the pwx2?
The giant motors are made by Yamaha, but are programmed by Giant. We don’t have an in-depth level of knowledge on them from a software and firmware standpoint as far as repairability mechanically, speaking identical. Rest assured the Yamaha don’t seem to have a lot of issues with hardware like motherboards, etc. However, if you ever get an error code for the torque sensor, then you should know ahead of time that is a motherboard failure in disguise. It would require the replacement of the motor. The PWX3 is something we are still learning about currently as it’s fairly new.
please can you help I need a diagram showing me what the connections are for on all the plug sockets on this motor. can you point me to anywhere. or send me a sketch.
i don't have a diagram but if this helps each plug has a unique key shape that matches the receiving port on the motor. Not sure what you are trying to do but most bikes have controller, speed sensor, and lights. I haven't seen many configurations beyond that from most bike manufactures so odds are you have something similar. What is going on with your situation? maybe we can help.
Mystery. 2018 Levo. Motor stays engaged after it quits adding power so you can feel yourself pedaling against the motor. Like regenerative pedaling, lol. So is that a sticky clutch? Or what could it be.
So if I understood you clearly it’s simply hard to pedal the motor? If so you likely have a crank bearing or bearings that are dead. You can send it in for service. We don’t charge to inspect and we can let you know what we find before we ever get started along with options. Fill out this for before shipping. Feel free to email us if you want to continue the conversation. ebikemotorrepair.com/repair-overhaul-service/
@ebikemotorrepair Hi Michael, can you help me to troubleshoot an problem? Main shaft(the one with pedals) is slipping time to time. I change one way bearing with Heavy duty one. Still slipping. I think main shaft or bell housing is thorn. Can you give some values in metrics, outer diameter - shaft, inner diameter bell housing? Or to point me to the right direction? Regards.
Do you sell the Brose 1.3 complete with the X ring and orange seal mods etc as a new swap out replacement ( C972) ? Im so far away from you the freight there would be part way toward a new one anyhow.
we dont sell new currently. We only offer repair to existing motors. What is your location? lets discuss further via email service@ebikemotorrepair.com is going to come to me (michael)
This is really interesting! ...And disheartening at the same time. I'm mechanically inclined, due to my hobbies, and my work. So I understand everything you show here. That makes me doubly frustrated, as I'm looking at a new Specialized Turbo Levo right now, as my next eMTB. Knowing that the motor has all these design shortcomings, makes me very wary of putting down several thousand units of my hard earned cash for it. I would like to tear into the motor while it's still new, and do all the sealing to make it at least somewhat more resistant to the elements. Unfortunately, I don't think the manufacturer would approve of this, come time to use the warranty. I actually think, that mountain bikes in general are really flimsy from a mechanical point of view. They're fun, and useful but sometimes you just have to wonder if you're getting you're moneys worth.
all the motors seem to have some cons so i can't isolate brose. I would think of it more like the price to pay for the fun. It isn't unlike having a dirt bike, motors will give you problems. I would definitely not open a new motor as it will void a warranty. If I were you get that nike and have a blast and expect some day you will need to repair or replace your motor.
Amen. I´m in the same situation and whenever a manufacturer tells me I can´t service my own, I won´t be giving them my money. Especially when their engineering is this much lacking.
Hi, my 2018 Turbo Como, Brose motor torque sensor seems to sometimes stick for up to 1-1.5 second when pedaling at some gear ratios. I also noticed sometimes I hear electric motor sounding cogging sounds when under heavy load. (Noted that at 6:31 you mentioned sometimes it's only a simple low cost sprag bearing that can be at fault) Is there a fair chance that these symptoms could be simple fixes (possible DIY route with right parts/tools) or is this motor complex/prone enough to water damage/wear that I'm better off getting a new motor? Thanks in advance :)
I would strongly recommend you send this in for service! you might have several things happening and non of them seem to be related to the torque sensor as the problem,. ebikemotorrepair.com/repair-overhaul-service/?v=9a0d701a3b2a

all the motor manufactures have cons. I would advise getting the bike and enjoying it all the way. just anticipate in the future you will need to repair or replace the motor. Just like almost every other component on your bike will likely have the same fate.
The SL is manufactured by a completely different company and is all gear driven. Also if you ever get a bike with a brose no you don’t need to add it for preventing anything. They put an industrial equivalent on at the factory. Except for the latest s-mags with the new polymer belts. Those are best dry.
@@ebikemotorrepair Thanks for the answer, I couldn't find a proper video about the SL motor being taken apart, I just assumed it was also belt driven. Is there a possibility that you guys might do a video on the Levo SL motors seperately? Thanks
This has definitely been the center of some hot topic discussions throughout the Internet. Personally, I’m kind of indifferent but definitely think they were ill informed about who was going to be using these motors. I think in a stable calm environment these motors are pristine pieces of engineering. As soon as they get exposed to moisture and blunt force that’s when they start falling apart. Lol Which, of course is exactly the demographics and their intended use. Abuse may not have been accounted for. but personally I have no engineering background but could certainly see the challenge that it must be to keep weight low, cost low, battery consumption low, and power and speed high. I guess there has to be a little Achilles’ heel in every design. One more little nerd moment here: I also believe no matter how much you simulate or pilot test something you will never know the true nature of an invention until it is applied to the masses in the millions of units. That’s where you really see the flaws come to the surface. I just don’t think there’s a way to test for that. I’m a patient individual and can say that what we are seeing now in the evolution curve of these types of devices is very exciting and encouraging. It will certainly take some time, but I will be willing to bet that whatever comes from all of this in the future we will see some magnificent machines hit the market. fingers crossed.
Hello, I can help with a planetary gearbox for Brose. We have our own development, which is currently being tested. This gearbox is much more reliable than the one installed from the factory. Production in any number of pieces.
Hi , I am very interested in servicing the planetary gear side of Brose, would like to see how. And as you probably know, should I add a grease to the planetary plastic gears my research says Molykote, PG 75 do you agree? Thanks
Hey great video💪🏼⚡️ I’m riding a 2018 kenevo, and it sounds so loud, my previous bik (Levo 2017) didnt make a sound at all.. Do you know what is causing all this noise 🤷🏼♂️?
It’s always hard to say without testing it here at the shop. But more often than not loud noises from those motors typically come from the planetary gear cluster. In some shape form or fashion. There’s actually several places where noise can occur. But sometimes it’s an harmless noise and nothing to worry about. Other times it might get progressively worse. Other times it might be a symptom that the planetary gear cluster is close to failure. However, there are other things that can make noise also in those units. I’d ride it out until something happens and send it in at that time for service ebikemotorrepair.com/repair-overhaul-service/
It’s the same motor as the Bros. just has programming and software from Sram. I’ve had a chance to demo one and it is a really great time. Does auto shifting for you. Feels amazing. It’s probably gonna have the same problems at all the other Bros motors do. Just keep this in mind. All eBike motors eventually will have problems. Some for different reasons but it’s just kind of the cost to have fun. You get one and have problems with it outside of warranty you be sure to come see us and we’ll get you fixed right up.
@@ebikemotorrepair I’ve broken both EP8s I’ve had - cracked spindle at 100miles and cracked spindle at 2000miles I ride about 1500-1800miles a year Shimano doesn’t stand by their motors and wants to blame everyone else so I wanna make the change to SRAM (Brose) or Bosch but having just learned Brose is belt-drive I wanna know what to expect Re: longevity before needing new belt or other maintenance. The EP8 works well but the spindles are for shit. Closed system so no maintenance
Great video covering the problems , iv'e come across your video searching my own failure trying to figure out what could be the problem. I have a Brose 2.1 in a Kenevo 2021. i pulled off my drive and thought that doesn't feel right then rode 100yds and the motor made a loud whirring noise and vibration through my feet . I stopped to check it and it powered down and now unable to power up the bike but rode the bike home with the power off. When i try to turn the front sprocket backwards it has resistance and feels notchy , from your experience would you say it could be the electrical motor or planetary unit failure and is unrepairable? thanks
@@markfoster1697 so first of all other than a hardware failure there’s really not a lot we cannot fix and these motors. However, there are several culprit that can manifest a similar symptom. Your best bet is to just send it to us for an inspection. Let us crack it all the way wide open and see what the heck is going on in there. If you visit our homepage, there is a big green button that says open a service ticket filled out that form and send your motor in. Also let us know if you have any questions as well. Emails is probably the best platform to carry on a deeper conversation about everything but feel free to reach out.
@@markfoster1697 worth mentioning… since the video was published we made a way to remove and replace the planetary gears and have not yet published an updated video about it. Work on that now actually n
Can a 2021 motor (Specialized SL 1.1, 35Nm max torque, 240W) on a Specialized Turbo Levo Carbon Comp SL be made quieter? I understand the newer motors are much quieter. If not, can the newer, quieter motor replace the older one?
We serviced and replaced a belt on this motor and now the motor is working backwards, you can pedal backwards and the chainring is moving with the crank but we have nothing onward, no resistance nothiong can you help ?
How about a good pair of AirPods? Haha. Sorry couldn’t resist a little humor. That’s way beyond my capabilities. I’m not sure what one would do to achieve that.
@@ebikemotorrepair honestly, that’s probably the only way or else they would have done it. I’m curious to understand how those high frequencies are escaping. It’s like 17-18khz on my Gazelle (Bosch). Can’t “hear” it but can feel it. If Specialized doesn’t have that I would switch over.
Hey guys, just watched your UA-cam video on brose motor ebike repairs. -I own a specialized Turbo Levo Comp 29 ebike. -Who do you guys recommend for specialized Turbo Levo Comp 29 Motor repairs in the San jose, California area? Greatly Appreciated....
The power in my Brose TF Sprinter equipped Ride1up e-bike shuts off a minute or two after I turn the power on. The screen glows blank and power from the motor shuts off. Is the motor controlled by the control panel. The motor has only 70 miles on the clock.
@@ebikemotorrepair No. I am the sole owner. I have not accessed the motor. The control panel has been eliminated as the source of the problem. The seller has been sympathetic and helpful, but the the bike is still dead.
@@waterboxer87 that symptom jumps out to me as a wheel sensor disconnected or not plugged in correctly. They will get about 6-8 cranks and then shut out. I would start with a simple injection of the plug first, make sure it is pluggento the right hole and the correct orientation. lots a little round one. They have key channels and only go in one hole and one way. if that checks out I would then inspect the magnet and sensor at the rear wheel to see if either are out of place or loose. Also, to your other question the main operating system is actually in the battery. the motor sends power to the controller from the battery and receives info, but both the controller and the motor are basically slaves in the ecosystem.
@@ebikemotorrepair I am thankful for your help. The speed sensor system is properly aligned and connected. I am expecting a test battery from the vendor. Fingers crossed.
So, brose really never fixed their original problems , but rather calmed riders down by increasing the warranty period and convict g people that the belt etc.should be considered regular maintenance problems . Yikes ! i almost bought a Nox Emtb from austria when the brose first came out and then heard of all the horror stories . fortunately the company added the newer Sachs RS motor , so i bought that . three years and not much kilometers later i've encountered termed zero problems . fingers crossed .😂
That’s good you found something that works for you. Yeah Bros didn’t really do a whole lot to the motor over their legacy so far. They have recently improved the Sprague bearings and the belts. They’ve also gone through multiple iterations of software which seems to have helped as well. But they are definitely on the struggle bus trying to sort out the glitches. I am optimistic in time we will see them get there. Because, that motor is a great performing motor all around. Powerful and quiet.
These guys rebuilt my Brose motor. Better than new! Excellent support and service.
Tanks for the feedback!
Sweet! Just ordered a Turbo Levo 3d gen, and very happy to know there are avenues to fix these common problems after warranty. Thanks for the video! Very confidence inspiring! Future Customer here lol
What a great attitude about this!! thank you for the feedback. I totally agree and frequently find myself talking people down from various frustrations about having to repair motors at all. So, i't refreshing when we see people who understand things break and then glad when there are service options available! Have a great day, enjoy the new ride, and feel free to reach out any time for troubleshooting or problems. 😁😉
Great video. Hard to believe that they do not have any seals or o rings to keep the water out.
We have discussed this many times here in the shop. The big question “why not?“
We kind of make a joke that perhaps a seal will produce just enough drag to reduce the battery life by about 0.02 seconds and God forbid a published charge time not be a few milliseconds better than the next competitor battery life. 🤣🤣🤣
Great detail information. Thx Michael for fixing my motor. This is the place to go for after warranty service. Saved my 50lb paper weight.
You've serviced my motors twice and i swear they run better than new!
Sweet!! Good thing you can ride enough to get so much use like that!
Aloha. Thanks for the great info. I've worked on many kinds of gearboxes and sophisticated drive units over the years. And often, yes, having the right tools is the difference between success and failure.
It’s so amazing how much of a difference it makes. In the early days we were using a lot of home made rigs. Once we had tools manufactured for specific purposes it was a game changer. You couldn’t pay me to go back.
Awesome to have found you guys on UA-cam. My Levo motor is doing fine, but it’s nice to know you guys provide this service if/when I need my Brose motor serviced. Cheers.

Excellent explanations. Thank you.
I heard a crunching noise from my motor yesterday while riding the muddy trails. After washing the bike today the noise if not there in my street test ride. Any ideas?
It’s hard to say for sure, but you may not actually have a noise. Sometimes noises can be tricky to trace down the source. Most likely if you had a noise that would. But again, without having eyes on, it might be a little tricky to troubleshoot. If the noise comes back and is consistent, then you could consider shipping it to us for an inspection. But considering your problem went away after you watched it from what I understand, that sounds like something was just noisy outside of the motor.
Hi.. Great video. Are all these issues also present on the 2.2 motors from the 2023 Specialized turbo levo line up? Also, comparing Brose, Bosch and Shimano, which are the best motors in your opinion?
I get asked this a lot. So far, I must say they all have pros and cons. I tend to persuade people to buy the bike first and consider the motor second of the ones you asked about Shimano is my least favorite since it’s almost impossible to service them once they’re out of warranty. Speaking purely as a rider I have no fundamental performance complaints about the Shimano. speaking as a mechanic…. I wanna throw them all in the trash lol
Yes please, I've just had the clicking sounds, thought it was small stones hitting the frame, but at the same time the power was intermittent . Have you heard of this?, also when blasting over roots or rock gardens sometimes the motor jumps into recline then back into turbo😢
It might be something else altogether. Sometimes problems will manifest and it can be easy to assume it is something like what you suggested. however it might be the clutch bearing in the drive pulley going bad or bad already. You should send it to us for inspection. We can see what is going on with the motor. Also, it is possible you have several things occurring. Repairing the health of the motor will help diagnose other potential problems outside the motor. These are usually fairly easy to diagnose once the motor is fixed. But I will be willing to bet everything will get back to working order once repaired. Please use the service ticket on our site before sending us anything .Thanks for reaching out. ebikemotorrepair.com/repair-overhaul-service/?v=7516fd43adaa
Was chatting to my local bike shop and they were working on a specialized ebike. Had to send the motor off although it was derestricted specialized still honoured the warranty, purely on the basic that they know the belt still fails regardless if it has or hasn't been derestricted
Id count you lucky. Not everyone has the same experience.
@@ebikemotorrepair wasn't my bike, just them telling me their experience dealing with specialize
@@bb7115 oh I see. Got ya. Either way whoever’s bike it was many shops flip out when they’re derestricted.
@@ebikemotorrepair thats aright. It does depends on the bike shop
This video has just convinced me to buy a hub drive motor ebike. Much simpler and less to go wrong
@@fractalofgod6324 ok but hub motors fail just as frequently and are not easily repaired due to most manufacturers don’t even offer support of any kind. Plus in many cases to change bearings you have to remove the hub from the rim. This is a lot of work. I’m not a huge fan of hub motors for the use in mountain bikes or serious commuter or road bikes. If you’re just putting around a beach town or golf community then hub motors are great.
Thanks! Good to know how it all works
yeah it really helps to visualize.
This is a great and highly informative vid thx a lot ...!
Awesome video! You answered to a lot of questions I didn't even know I've had!
But I'm still wondering why this motor even needs planetary gearset? It seems like it is the only thing that is unfixable. Why they did not just put that gear straight on the motor shaft?
Im no engineer but I have my moments. I would say it is there for support. In most internal motors the drive spindle is quite close to the internal motor. The drive spindle in the brose is a significant off set distance away from the internal motor. Like by nearly 2 inches. Make sense?
Really good video, what would the average motor do mileage wise before things like the belt or bearings go on the Brose 2.2 Turbo levo?
On average around 3000mi. But it’s subjective. Riding conditions, rider weight, drive train, how hard it’s ridden, and other factors can effect the life. Like anything with a performance motor the harder you push the more likely something will break. There’s also the chances for small manufacturing defects to pop up and cause early death. But most customers get about 3000mi. One guy got nearly 12,000mi on a factory brose!! 😳
That’s unheard of frankly. But still. Pretty cool.
Do you see many Levo 2.2 motors? Presumably most are still under Specialized warranty?
@@ThePiggly_Wigglys yeah most are under warranty still. But we have seen a few already with customers who don’t want to bother with warranty wait. Although we always advise not voiding the factory warranty. I mean free is hard to beat even if it means a little more waiting.
@@ebikemotorrepair Thanks so much for replying. I have heard others say around 3k too which if the case for me ill be happy with.
Am I the only one noticing that this is 'bad by design'? How d4F such thing was built and sold to 10-15K $ bikes?
They first started being used as electric power steering motors, then converted to ebike use, I have one & I work on them in our fleet of rental bikes.
How much larger does the ebike market have to get before ebike motors start getting designed from scratch for bike use and then adapted for power steering retrofits?

That’s wild. Yeah share your experience and pictures. Service@ebikemotorrepair.com
would you know what's wrong with it, if you only hear grinding noise from the motor when you on the higher gear? meaning when going uphill, the motor start making the grinding noise.
@@RonA-s1g these kinds of noises, believe it or not can be quite tricky to figure out without tearing into the motor. And sometimes we find that it’s not the motor at all. You should try riding with the motor off and see if you can still get the sound to occur. it doesn’t rule the motor out completely if you still hear the sound, but it sure does begin to pinpoint the only possible culprit in the motor. Also, this would highlight a lot of other culprit outside of the motor. Such as pedals, crank arms, chain, rear, cassette, etc.
This is fabulous!! Thank you !! I have a motor that has difficulty disengaging assist but can be disengaged pedaling slightly backward. Thoughts? Torque sensor? Sprague Clutch? Brose 2.1 Motor , Thanks !
Many times that is the needle roller bearing getting sticky with the shaft. An overhaul may be in your near future.
Thank you !!
Great video, thanks. In you biz card at the end, I see the listed 5 motor makers. Do you also repair Shimano, Specialized, and Bafang motors? Thanks again.
Not sure how we missed this comment. but to answer your question specialized motors are all either SL or Brose. We service both. We have a kit for both bafang mid drive and shimano line-up. But both bafang and simian are not motors we offer service for. The bafang are so cheap usually to pay us to repair them you are almost at the cost to replace it. The shimano motors are too tricky as they have booby traps that can sense if the motor has been opened which will make the motor fail completely.
Great video. Please do the same for Yamaha PW / PW-X series motors so we know what to look out for / preventive actions etc. Thanks 😊
You got it my friend. We are currently doing one on Bosch. As it is a much more popular motor than the Yamaha and some of the other motors. But we will add the whole yammy legacy to our what’s wrong series thanks to you!! Meanwhile just for you…
Yams are really simple. The most common thing we see is simply sloppy drive assembly bearings. Mainly left and right. Then we also see the drive gear (small nylon gear that transfers power from internal motor to the drive assembly) can break off teeth during sudden change in load. Also inside that gear is a small clutch bearing. If the gear starts to crack near the center it can allow the clutch bearing to slip inside the gear working against its its purpose.
Lastly, there’s a common “torque sensor error code” that actually spells game over. The motherboard is to blame. It’s a fault that prevents the motherboard from actually seeing the torque sensor. So it won’t see a new sensor either. And the unfortunate part is a motherboard is keyed into the exact magnetic field of its own internal motor magnet at the point that f manufacturing. Meaning the motherboard isn’t something we can “swap” if it’s faulty. Replacement time in that case.
Can’t say we have seen much more on the yams. But we love the freaky things so let me know if you hear any good odd stories.
@@ebikemotorrepair Thanks for the detailed reply 👍

Hello there from the Netherlands. Maybe you can advice me on this one: Yesterday evening I tried to launch the light and on the display it gives a error code 0x91. I found on the internet that the Fuxon light on my Bulls Lacuba EVO Lite 5F causes the problem. Can you advice me ho to solve it? Best Regards Hans
Try working with your bulls dealer or bulls directly as the first steps.
I have question. My belt was totally stripped so Im gonna change that but I noticed that I cant turn the motor with my hands. Is that normal?
Yes, totally normal. The side case cover that you took off to reveal the belt actually holds one side of the magnet spindle. The front drive, spindle and magnets are all run unit. So when you remove the cover the magnets drawn together with the copper slap against the wiring on the inside.
I have a Gen 3 and just had a slipping issue @ 2000 miles. I actually thought some of the teeth on the belt stripped out until I saw this video. Also, I cannot believe that these motors aren’t sealed from the factory. I had no idea that water could just go in the motor so easily.
You likely need a new set of clutch bearings. The belts don’t “slip”. When they fail they go pretty much completely. You should send it in for inspection and we can let you know pricing options.
I am still under warranty thankfully. Shop is replacing the motor. I'll keep you guys in mind for the future though for sure. @@ebikemotorrepair

yeah definitely send it over for any trouble. There haven't been too many problems we can't fix.
Great video, thanks! In your opinion, based on the quality of the design and components used, and taking into account the number of repairs you do on the Brose, how does it compare to the Bosch? Ordered a Levo with a Brose 2.2 motor but hearing lots of horror stories, mostly on the older Brose 2.1 to be fair, but wondering if I should find a Bosch CX gen 4 powered bike instead. Appreciate any insights you have - thanks!
We definitely repair more brose than Bosch but I suspect it’s because there’s simply more of them in the US. I’ve been trying to find some metrics to see if the ratios of failure are similar based on how many units there are. I suspect issues will have a similar statistic across all the motor manufacturers. But they all have different kinds of stuff go wrong. So it’s hard to say.

@@chetanrazvan3896 its noisy is the only down side , like an RC car from 1990 , but cant fault that 18k for sure , i had a felt 9E20 and the bosch was a great motor for sure
Great post, thanks lads.
glad you like. this is basically most of the conversations we have on the phone daily so we figured it would be relevant.
In my 2018 Fantic Integra 180 w Brose gen 1 alut motor there is one odd feature. After 5 to 10 minutes intense riding with boost power setting it a bit looses power and isn't cinsistant with power delivery within one crank circle. And always when I then do a couple of cracking circles backwards, the motor immediately starts delivering boost power as it should.
Has anybody experienced similar and maybe found what wrong?
What do you Bike Motor Repair guys think about that?
@@karraite that is actually odd behavior. It is possible that you could have either a power delivery issue such as a connection, plug or socket or even wire harness that is faulty or damaged. Your battery could be going bad. There are also some clutch bearings in those units which can begin to slip. However, the backwards rotation fixing your problem, is a bit mysterious to me. When you have the intermittent power, are you seeing any error codes?
thanks for all the tips, trying to asses if it is worth replacing my belt and bearings on a 2017 Sp Vado. I am experiencing so issues on the drive side. it is incredibly stiff to turn the planetary gears even thou it all looks clean and good. I guess the bearing behind the gears is gone. does this make it scrap? Thanks for the video!
@@oliverbruchhauser9342 in almost every case we have an option to service the motor for less than replacement cost. Definitely worth sending it to us. We don’t charge to inspect.
Hey man, interesting video.. I'm waiting delivery of a new levo with the 2.2 motor. Live in the north of Scotland so it gets pretty wet here. I'm thinking about running a bead of silicone grease around the water ingress points you mentioned behind the crank arms. Do you think this is worth doing? Thanks in advance for any advice : )
Definitely DO NOT do that. That gap is Actually 2 independently moving parts. It needs a proper crank seal as what comes with our kits. but installing it would void a warranty. Alternatively you could swipe some marine grease in there but it isn't a permanent solution at all. but it will certainly help a little. I would ride the warranty out before modifying or upgrading. when its time you should check out our partner in UK they are awesome!! www.ebikemotorcentre.com

@@ebikemotorrepair I’ll give them a call, hopefully the x-rings are available to order?! Yeah, I meant a silicone based grease, not a sealant so yeah marine grease could be a good shout. It’s gotta be better than an open void
@@andydtkd ahh I totally missed that in your original comment. Sorry. But yes something is better than nothing. Once out of warranty send it to our partner in UK to seal it properly. You won’t regret it.
Great video! What is the best greas for the planetary gears to be the most silent? I tried a lot of type, but the most quite is the original, just i do not know what that could be.
Usually don’t need to grease them. If they’re making noise it’s likely the beginning of the bearings failing in them. Unfortunately when they go it’s time to replace. But to answer your question we use a MOLYKOTE PG-75

i just pulled apart a mag s its fun to fix
I am looking at a Vado bike, but these motors seem to have several failure points that could be easily addressed by Brose themselves. Here in the UK it would cost £200 to make the Brose motor watertight and stronger, seems daft that I must spend another 200 on an already expensive bike.
What is the best manufacturer of midmotors?
Just bought a kenevo... is it a good idea to send it to yall when new to get those seals put in? Would that void my Warrenty? Or should I wait until the warranty is run out?
I would advise you riding out the warranty. After that if it gives you any issues then send it in for service.
Hi @ebikemotorrepair, which parts do you recommend for Brose T in order for seal it preventively? Would those x-rings be enough? Also do you ship to Poland? :)
we have a partner list here so find the closest to you and work with them. Also there are several additional things you need to completely seal the motor. where to buy: www.ebikemotorcentre.com/where-to-buy/

Thanks glad you like it.
Hi Micheal..is good to know are folks out there that know how to maintain my pride and joy..my freedom…
Trouble is, I’m in Oz on the other side of the world..!!
Do you know of anyone in Australia that does comparable work to yourselves..or is there anyone in Oz reading this that can put me onto someone here doing comparable work, with upgrades and seals..??
I don’t use the app with my bike, so have no idea how many miles..but it’s a lot..! I often ride remote, and would hate to get stuck due to lack of maintenance…
We actually have a partner in Australia. Check them out. Definitely let them know I got you guys in touch.

Looks like a complete under engineered piece of junk. Unfit for purpose comes to mind. If that kind of build quality or lack of was fitted in cars etc there would be a law suit against the manufacturer. I think quality like that is totally unacceptable ! Where are they made?
They are made in Germany actually. And yeah that would be quite unacceptable type of treatment if this were in the automotive world. Although in my opinion one of the biggest problems with the Bros motor is in fact that it’s over engineered. They were trying to keep the weight down the power high and the noise low. The Bros has more moving parts than any other motor that we service. Classic German engineering. Super complicated and high-performance for some amount of time at least. Until it breaks. 🤣
greetings from Brasil. What's is the diference between the motors brose 2.1 for 2.2?
Software and better belt from factory. Otherwise the same.
@@ebikemotorrepair thanks
Any ideas what went wrong? What the problem might be??
my turbo Levo is 1.5-year-old, I was cranking up a hill, then my motor made a high-pitched free-spinning sound and the pedals & cranks would not engage the motor but just spun without moving the bike. I turned the power off, coasted down the hill. turned the motor on, it worked for a few minutes then repeated the same symptoms, i turn power off and got off and waited a minute and turned power on and started pedaling back. still 5 miles away from parking lot i kept repeating the off on thing until i could build enough forward momentum to coast back. load the bike I went home about 30 min drive. at home, i had to see if the problem still was there. turned it on, rode around my half acre yard, it was working fine so i kept doing laps, harder and harder but it wasn't failing. i don't have any hills in my yard, but i tried to crank harder and harder and after about 15 minutes it finally failed the same way again. on my specialized app i did a diagnosis and it pulled and error code: SL1-B-HS-256
you likely have a failed belt pulley clutch bearing. I would strongly recommend sending it to us for inspection. We dont charge to inspect and will gladly take a look at it for you. be sure you fill out a service ticket before sending anything our way. ebikemotorrepair.com/repair-overhaul-service/?v=7516fd43adaa
Hello nice movie...but is the brose s engine the same engine if it 45kmt and 25kmt...I ask because my 45kmt is done...I have a offer on a 25kmt.they look the same? Best regards Brian
Thanks for the comment and for watching. So, those motors are mechanically the same but obviously programmed differently. Each motor needs to be programmed specific to its bike. There are all kinds of things the motor need to know to operate properly or at all in some cases. I would advise for brose working with your bike shop for a replacement rather than buying second hand. However we buy old motors for salvage.
2k miles on my 2018 kenevo i believe the belt is starting to slip but only on heavy pressure peddling is that kinda normal for 2k miles
@@ZRome187 hi there. Thanks for your comment. We can definitely help you fix the problem. However, belts don’t slip. When they break, they fail catastrophically. Usually slipping is a result of a failing clutch bearing inside the belt pulley. I bet you are due for an overhaul. If you will visit our website and fill out the service ticket form and send your motor on it. Also feel free to reach out for any questions through our website. EBikemotorrepair.com.
That was quite helpfull. Many thanks.
My pleasure! We hope to make more. I don’t fancy myself a UA-cam star but if you or any of your riding buddies have anything else of interest be sure to let me know. Will will try to build some contents around it.

Hi, great video! I'm looking for the video about Bosch you mentioned in comment but can't find it on your channel, can you pleaae advice?
we haven't made a similar video on bosch yet. But we can certainly discuss it. Feel free to connect on our website form or we can try and connect on the phone.
Yeah, I would be very interested in your experience with Bosch, because I knew that Brose and Shimano had some issues but thought Bosch was better, but recently learned about some bad designed seals around the crank on the 2nd and even on 4th gen. I rode Bosch 1st gen for almost 15000 Km and without any issue, so I´m a bit surprised about these issues on newer motors.
@@stanolauko yeah Bosch have their demons as well. I’d say you got pretty lucky on that motor. But we repair them a lot too.
@@stanolaukoSame here, I have Bosch 1st gen, big metal engine, no failures. Now I want a new emtb with full suspension and I am a bit worried about the reliability of new motors
After my Turbo Levo stalled, I was able to pedal home and it was hard to turn. And I found that the bike does not roll backwards, does not go backwards. I disassembled the Brose motor and saw a belt without teeth and the planetary mechanism cannot be turned by hand. Please tell me this is the end of the planetary electric motor?
No don't panic. the spindle of the internal motor is held in place by the side case cover (also that small grey spindle is the same part of the internal magnets). when the side case is off it allows the magnets to attract to the side of the internal motor preventing it from spinning freely. You likely need only a belt. However if you send it to us for inspection we can take a look at the rest of the motor for you. We dont charge to inspect.
@@ebikemotorrepair I reassembled the Brose electric motor without a belt (it is impossible to buy it from us), changed the overrunning clutches, turned on the pedestrian mode with the button on the steering wheel, the motor worked for a few seconds and turned off, I did not release the button. The battery is in good condition. What is this? Why did the motor turn off? Maybe the firmware of the motor has flown?
@@ebikemotorrepairunfortunately I can't send you the motor because I'm from Russia
@@СашаПетров.Жизнь I believe it is simply detecting something is wrong internally and self shutting down. Please clarify, you mentioned belts are impossible to find. the way it reads is from the US? we sell them. Unless you mean something else? Where are you located? We have worldwide partners.

Hi, i have a 2.2 which stopped working only 10 hrs after having the speed limiter removed via plug in system. I have been told it might be the torque sensor ??? is this something that can be repaired ??
we can repair them yes. If that is in fact what is going on. But we are wizards at troubleshooting. if you want to send it to us for inspection please see our site to fill out a service ticket.
What do you recommend that a new Levo owner do to protect their Brose motor from water? Your adding an oilseal outboard of needle roller seems like a no-brainer ( why don't they do this at factory???) but may void warranty. So what would you do if you bought a new Brose bike?
So I’m a big believer in warranty support. If somethings under warranty and it breaks let it break. You could put a little grease down in that gap between the shaft and the sprocket carrier and that will certainly not void your warranty. At least I would be very surprised if it would. You could also put the X ring on the left side Between the case and the crank arm. That certainly won’t void your warranty. While this isn’t bulletproof it should aid in preventing bad dust and water ingress into the unit. Otherwise I would play the odds and just fix a motor when it starts giving symptoms once it’s outside of warranty and then fortify the motor at that time.
@@ebikemotorrepair Thanks. I suspect most people agree with you but for me it seems quite insane that Brose do not install that ($1?) oil seal at the factory knowing that water will get in and start corrosion from the first wash of the bike. Sure it may take a couple of years to do serious damage but why even allow it to happen at all? Warranty replacement is great (for 2 years) but then what. I would prefer a motor that does not need replacement because it got wet - e.g. every EV car motor in the world!
If you could get Specialized to certify(allow) you to waterproof/upgrade motors under warranty then I would seriously consider doing so.
@@ebikemotorrepair is there any specs for X ring?
Great insight into these motors. Do you have any videos/advice about these motors cutting out after a few turns of the cranks?
sounds like the speed sensor. Either you have it plugged in wrong, the magnet has shifted, or the wire is damaged. But this is how it behaves when the motor is unable to get info from the wheel sensor assembly.
At 18:20, you say the motor knows specifications related to crank arm length, wheel base, etc.
My Turbo Levo Comp came with 165mm cranks. I have since replaced the cranks with 150mm. Am I hurting the performance of the motor?
Thankfully, I haven't had a problem yet. Even while running unrestricted.
It certainly doesn’t hurt the motor, but it may not perform as good as it could. I’m not exactly sure which way the power map would be affected by a shorter crank arm length I would have to think deeper about it but what would occur is power delivery difference. A shorter crank arm length will produce less torque on the torque sensor. So knowing that length is how the system compensates for power delivery.
Great Video! I just changed the belt on my drive smag engine and unfortunately removed the cover from the electronic side, the pins to the torque sensor are still straight but i get engine internal error , try to think about a workaround to check it without removing the drivetrain
We remove the drive shaft assembly to make sure it’s correct. Honestly you should send it to us for that. We can inspect the rest of the motor for you too.

You probably have a belt pulley clutch bearing that failed. You shoal send it in for service. What part of the world are you located?
where can i buy a rebuild kit for this motor? my vado bike broke and i am trying to fix it.
You can buy from us but we strongly encourage you to send it in for service. We have tons of experience and tools and can likely help you avoid causing other issues.

Great review thanks! I read a lot about the noise problem with Brose 2.2. There are a lot of complaints about very heavy noise from the motors. Some people experience it with the new bikes, and some have the issue after some period. What can be the reason for that?
That’s a great observation you make. We have seen it as well. Some of our customers say they’re on their fifth or sixth warranty within a few months of some of the newest bikes. We haven’t gotten any official response from anyone official within Brose. But, we speculate they must have made some changes within that model range the internal motor that could potentially cause the planetary gears to put unwanted stress on the bearings that support the magnets. Again this is pure speculation not an official diagnosis. But something seems different for sure. Mostly in brose noise occurs when the bearing stack inside the front drive spindle starts to loosen inside the front drive spindle itself. I can make a video about this once we have enough statistics to go on. Until then it’s smart guess work.
@@ebikemotorrepair It would be great, thank you!
New turbo levo comp carbon Nov 2022, I got one for me and one for my wife and hers is quit and mine if very loud after 20min or riding. Bike is in shop now and hope it will be covered but more so that the problem has been fixed. So if specialized dose not find a fix for the 2.2 motor and you do please post or let me know as I would pay to have a quite motor for sure. It is very sad that I now want to sell the levo and go with a different brand. you would think after all the problems with 2.1 the new 2.2 would be rock solid.
@@843raptor yeah some are louder than others too. Not a lot that can be done about it from a mechanical side. It's due to nuances in manufacturing as far as we can tell.
Just wondering, no matter what the motor is sent in for or whatever the issue is, do you always do all this other preventive maintenance that you’re showing in the video?
it just depends on each person's unique needs. Some people are on a budget and we can have a fix-whats-broke mentality. Others want a middle road option and some want the top shelf service. But we dont charge to inspect and will give you our recommendations ahead of time after we take a look at it.
@ebikemotorrepair - question for you - I have a 2022 levo and the motor works fine, however, it get very loud when it gets hot. After about 30 mins of riding its so loud you can hear me coming a hundred yards away. Does this mean my motor is going to fail soon or is this normal in the newer motors? Thanks!
we have seen this occur on some of the newest bikes. Not 100% sure the cause just yet and it is possible it is just a noise motor. It is also possible you are hearing the early stages of the planetary gears beginning to fail. but it's really hard to tell for me without inspecting it. Ride the warranty out and once out of warranty if you are still having th problem send it to us for service. we should be able to figure it out for you.
Question for you. I have a BH ADAM. X. WHEN I PEDDLE I hear a noise and it seemed to bind and and hold the chain to it would bind. When it's off it peddles normally. Any suggestions would be appreciated.
Would need to inspect it to know for sure as several things come to mind. Send it in for service we don’t charge to inspect. Ebikemotorrepair.com
My 2021 Turbo Levo motor is making a noise like a spoon hitting a tin plate on every crank revolution. It immediately stops for a little while when I back peddle 1/4 turn. About 5 minutes later it starts again. Any idea what's wrong?
You should send it in and let us look at it. Here is a link to our service ticket generator. ebikemotorrepair.com/repair-overhaul-service/
Would you say that the current Specialized 2.0 (Brose) motor found in the current Turbo Vado 4.0 models is as reliable as a Bosch Performance Line?
I’d say similar life spans baring manufacturing defects.
Wow! I thought Bosch was garbage. Maybe it’s a light weight competition thing. I got a rocky cause I like a mechanical diesel with torque that rolls coal, lasts forever, is more efficient, and easy to work on.
If you care to share your thoughts and experiences on Rocky Mountain please feel free. It’s such an uncommon motor we have had zero requests for services over the years. But we have dissected them. Feel free to email service@evikemotorrepair.com
I have a brand new Rockrider Decathlon with a brose C, to remove the 25km/h limit i have moved the sensor to the pedal and placed a magnet under the pedal arm but after 3-4 km the power cuts off and i need to restart the display on the bike to work again, can you provide me with a solution please? I did the same on my old Brose T motor and no cutt of problems just ERRORS from time to time.
yeah they are really trying to crack down on things like this and they can tell when its been tampered with so the solution is to leave it at a factory setting. I do know there are people who make chips that can over ride and make them faster but I am not familiar with the options also we have to stick to certain standard compliances with federal regulations so officially we don't get involved with modifying speed or power outputs.
Do the Giant syncdrives have any modifications, mechanical or software over the Yamaha motor it’s based on that limits repairability? Are the pwx3 less reliable than the pwx2?
The giant motors are made by Yamaha, but are programmed by Giant. We don’t have an in-depth level of knowledge on them from a software and firmware standpoint as far as repairability mechanically, speaking identical. Rest assured the Yamaha don’t seem to have a lot of issues with hardware like motherboards, etc. However, if you ever get an error code for the torque sensor, then you should know ahead of time that is a motherboard failure in disguise. It would require the replacement of the motor. The PWX3 is something we are still learning about currently as it’s fairly new.
please can you help I need a diagram showing me what the connections are for on all the plug sockets on this motor. can you point me to anywhere. or send me a sketch.
i don't have a diagram but if this helps each plug has a unique key shape that matches the receiving port on the motor. Not sure what you are trying to do but most bikes have controller, speed sensor, and lights. I haven't seen many configurations beyond that from most bike manufactures so odds are you have something similar. What is going on with your situation? maybe we can help.
Mystery. 2018 Levo. Motor stays engaged after it quits adding power so you can feel yourself pedaling against the motor. Like regenerative pedaling, lol. So is that a sticky clutch? Or what could it be.
So if I understood you clearly it’s simply hard to pedal the motor? If so you likely have a crank bearing or bearings that are dead. You can send it in for service. We don’t charge to inspect and we can let you know what we find before we ever get started along with options. Fill out this for before shipping.

This is really interesting! ...And disheartening at the same time. I'm mechanically inclined, due to my hobbies, and my work. So I understand everything you show here. That makes me doubly frustrated, as I'm looking at a new Specialized Turbo Levo right now, as my next eMTB. Knowing that the motor has all these design shortcomings, makes me very wary of putting down several thousand units of my hard earned cash for it.
I would like to tear into the motor while it's still new, and do all the sealing to make it at least somewhat more resistant to the elements. Unfortunately, I don't think the manufacturer would approve of this, come time to use the warranty. I actually think, that mountain bikes in general are really flimsy from a mechanical point of view. They're fun, and useful but sometimes you just have to wonder if you're getting you're moneys worth.
all the motors seem to have some cons so i can't isolate brose. I would think of it more like the price to pay for the fun. It isn't unlike having a dirt bike, motors will give you problems. I would definitely not open a new motor as it will void a warranty. If I were you get that nike and have a blast and expect some day you will need to repair or replace your motor.
Amen. I´m in the same situation and whenever a manufacturer tells me I can´t service my own, I won´t be giving them my money. Especially when their engineering is this much lacking.

About to get a new Turbo Levo SL, should I put some vaseline on the belt as preventative maintenance?
The SL is manufactured by a completely different company and is all gear driven. Also if you ever get a bike with a brose no you don’t need to add it for preventing anything. They put an industrial equivalent on at the factory. Except for the latest s-mags with the new polymer belts. Those are best dry.

Many a design flaw! I can't believe, didn't see the engineers notice this?
This has definitely been the center of some hot topic discussions throughout the Internet. Personally, I’m kind of indifferent but definitely think they were ill informed about who was going to be using these motors. I think in a stable calm environment these motors are pristine pieces of engineering. As soon as they get exposed to moisture and blunt force that’s when they start falling apart. Lol
Which, of course is exactly the demographics and their intended use. Abuse may not have been accounted for. but personally I have no engineering background but could certainly see the challenge that it must be to keep weight low, cost low, battery consumption low, and power and speed high. I guess there has to be a little Achilles’ heel in every design.
One more little nerd moment here: I also believe no matter how much you simulate or pilot test something you will never know the true nature of an invention until it is applied to the masses in the millions of units. That’s where you really see the flaws come to the surface. I just don’t think there’s a way to test for that. I’m a patient individual and can say that what we are seeing now in the evolution curve of these types of devices is very exciting and encouraging. It will certainly take some time, but I will be willing to bet that whatever comes from all of this in the future we will see some magnificent machines hit the market. fingers crossed.

great video💪🏼⚡️ I’m riding a 2018 kenevo, and it sounds so loud, my previous bik (Levo 2017) didnt make a sound at all..
Do you know what is causing all this noise 🤷🏼♂️?
It’s always hard to say without testing it here at the shop. But more often than not loud noises from those motors typically come from the planetary gear cluster. In some shape form or fashion. There’s actually several places where noise can occur. But sometimes it’s an harmless noise and nothing to worry about. Other times it might get progressively worse. Other times it might be a symptom that the planetary gear cluster is close to failure. However, there are other things that can make noise also in those units.

It’s the same motor as the Bros. just has programming and software from Sram. I’ve had a chance to demo one and it is a really great time. Does auto shifting for you. Feels amazing. It’s probably gonna have the same problems at all the other Bros motors do. Just keep this in mind. All eBike motors eventually will have problems.

All of the brose are basically the same. There are some nuances on certain things but mainly the same.
Are there any ways to dampen ebike motors? I'm talking about the really high switching frequencies 15 khz and up.
How about a good pair of AirPods? Haha. Sorry couldn’t resist a little humor. That’s way beyond my capabilities. I’m not sure what one would do to achieve that.
@@ebikemotorrepair honestly, that’s probably the only way or else they would have done it. I’m curious to understand how those high frequencies are escaping. It’s like 17-18khz on my Gazelle (Bosch). Can’t “hear” it but can feel it. If Specialized doesn’t have that I would switch over.
Brose, what a smart idea to have one ! 😀

The power in my Brose TF Sprinter equipped Ride1up e-bike shuts off a minute or two after I turn the power on. The screen glows blank and power from the motor shuts off. Is the motor controlled by the control panel. The motor has only 70 miles on the clock.
has anyone messed with it? like taken it out of the bike or anything?
@@ebikemotorrepair No. I am the sole owner. I have not accessed the motor. The control panel has been eliminated as the source of the problem. The seller has been sympathetic and helpful, but the the bike is still dead.
@@waterboxer87 that symptom jumps out to me as a wheel sensor disconnected or not plugged in correctly. They will get about 6-8 cranks and then shut out. I would start with a simple injection of the plug first, make sure it is pluggento the right hole and the correct orientation. lots a little round one. They have key channels and only go in one hole and one way. if that checks out I would then inspect the magnet and sensor at the rear wheel to see if either are out of place or loose. Also, to your other question the main operating system is actually in the battery. the motor sends power to the controller from the battery and receives info, but both the controller and the motor are basically slaves in the ecosystem.
@@ebikemotorrepair I am thankful for your help. The speed sensor system is properly aligned and connected. I am expecting a test battery from the vendor.
Fingers crossed.
Thanks, I know not to buy this brand but is there any brand that is designed to last.
Probably best to keep worrying about it and miss out on all the fun. I've got 4000 miles on mine without a single problem.
@wegder. @boblatkey7160 took the words right out of my mouth.
Merci pour la vidéo/thancks for vidéo, je cherchai ou ce trouvaient les planétaires, c est chose faite a la minute 15 ... carpe diem .
So, brose really never fixed their original problems , but rather calmed riders down by increasing the warranty period and convict g people that the belt etc.should be considered regular maintenance problems . Yikes !
i almost bought a Nox Emtb from austria when the brose first came out and then heard of all the horror stories . fortunately
the company added the newer Sachs RS motor , so i bought that . three years and not much kilometers later i've encountered termed zero problems . fingers crossed .😂
That’s good you found something that works for you. Yeah Bros didn’t really do a whole lot to the motor over their legacy so far. They have recently improved the Sprague bearings and the belts. They’ve also gone through multiple iterations of software which seems to have helped as well. But they are definitely on the struggle bus trying to sort out the glitches. I am optimistic in time we will see them get there. Because, that motor is a great performing motor all around. Powerful and quiet.
