i appreciate the cleanliness of your shoop
Thanks great insight into what to avoid on my E bike use and pity the manufacturers did not build the motor this way in the first place. Great video.
Brilliant explanation. I do hope that Brose makes you an authorized agent, and gives you access to the parts necessary to fix everything. You are doing them a big service, as well as you do for the bike community.
That would be very nice if they did :)
Great work! I'll be shipping my motor for an upgrade/overhaul the second the warranty expires!
This workshop does not look as a typical one...which shows how you actually work, congratulations...you have got all of my respect, it is a shame you guys are not in Spain, I would definitely send you my bike for the upgrade. Thanks for the video, excellent work Peter
Don't forget our guys in Spain are pretty good too. www.performancelinebearings.com/spain/
Thanks Peter things we all need to know and even better who to trust to do the work for us
Hey guys today I had to change the cable of my sram group set. Unfortunately that means for me to take out the brose motor. Thanks for your video by showing the 2 upper crews w/o sealing function although there these have a gasket. I immediately sealed my screws. make absolutely sense. Have a nice day riding your bike
Well thats clear. If I have a Brose problem, it's going here. The workshop speaks volumes about the service.
Great work Peter! ... Good to know of this fantastic service and upgrade you offer.
Fabulous, really well presented and explanation. Love your workshop!
Very in depth video thanks for Sharing this. Touchwood nothing gone wrong with my motor as yet but when it’s needed I know who to be sending it to👍🏻
That's the whole idea of the upgrade! Get it done so your motor doesn't fail! 😉
great information to know not scared any longer about the motor issues
My motor is coming to you for this upgrade the minute my warranty runs out!
Thanks heaps, I have just sent an E-mail to david trump here in Australia to have a look at my Gen1 Brose that seems to be having Sprag clutch slipping issues.
Great work mate I have been following you since the start.
Please, how did you get along, mate? I can't find any C.L.S in Gunalda listed.
@@slavojalois1639 it's in AUSTRALIA.
Gen 1 all fixed. New sprag and some other bearings. Thanks to all that helped. The bike is now sold and I'll see if the 2021 comp motor has a weak sprag now. 1000kms and all good so far but I'll never ride in the wet again.
Really interesting to watch, I’m considering different bikes to buy and great that you can repair motor issues. Thanks for taking the time to put these vids together.
Really great job!! If I would ride a Brose motor bike, this upgrade would be mandatory 👍🏻
What kind of sealant are you using at 24:01 on the screw heads?
We used standard RTV silicone gasket sealant at first, but now we use copper washers as they are more resilient.
Informative video, learned a lot about the motor in my Levo!
Wow fantastic workshop, your exaltation and detail. Looks like a fantastic business would love to spend a couple of weeks watching and picking your brain.
Nothing left in my head! The world has already picked it clean 😂😂
Awesome video! Thank you. Will definitely contact you if my motor began with issues.
Wow, fantastic breakdown thank you.
Wow,! many many thanks very interesting and exstrimely professional presentation
You mentioned at 8:21 you had a fix for the wear on the main shaft caused by the needle bearing deterioration, but I didn't hear what it actually was?
It's been a while since this was asked, but the fix is at 11:19
very good information and education, keep putting more videos out buddy #eMTBs
Thanks a lot!! nice work 👍🔧
Excellent breakdown
Thx a lot. Which dimension of x-rings have you been using to seal from outside? Seems to me an easy one together with sealing the screws. Thx again, very professional
These seals should not be fitted without removing the crankshaft assembly, cleaning and greasing first. This is vital and cannot be done while the motor is in situ. As for the dimensions, we had the seals manufactured to our dimensions and material specifications. A big investment and not really something I would want to talk about on here, sorry.
@@Ebikemotorcentre Accepted, thanks a lot.
Really good video and very informative.
I just brought my Specialized Turbo Vado SL 5.0 EQ (purchased in March 2023) into the shop as the motor failed. Hope they can fix it.
Well done!
Great, thanks
That's very cool guys, just wish you could do mine in New Zealand 🤔
We are working with a company in NZ and should be able to offer this service shortly.
@@Ebikemotorcentre please let us know once you have the details and are certain they are up to the same standards as your workmanship
wow!!! my brose t from decathlon has this water pb... i mail them ... very gently saying they need do a battery connector cover ... they say me : no cover have to let bike inside ... lol for mtb... theyre kidding... a silicone rubber o 3d printed plastic cover... for 2k bike is that normal ? i will send u my motor for upgrade ... ur the best ❤️❤️❤️
Thanks for great video with the details! :-)
Way too many issues with the existing motor design. I would not want this upgrade. I'd want a re-designed motor that did NOT have all these water leaks! GAH!!!
I am sure your wish will be granted on the next motor from Brose.
Hi, I am a bike mechanic in Brazil, I would like to learn more about the maintenance of these ebike engines, would you be able to point me to links or channels that I can learn? thanks for the content.
There is no one I would trust to point you too. Even our early videos are old now, we have learnt much and come a long way. I don't know how we can help you with this request, sorry.
@@Ebikemotorcentre thank you so much for feedback
Hi...Sensational. Could you tell me the torque used on the belt tensioner?
0.2Nm 👍 Don't forget to lubricate the carbon belt with "Technical" Vaseline, thicker and stickier than normal Vaseline (Petroleum Jelly).
All these eMTB motors should have old school tractor grease nipples. Wherever there is a bearing you're then able to push new fresh grease in and your can push old grease and dirt out. The "outer outer" seal is an easy replacement part and you change it maybe every 2 years. Behind the "grease seal" you then have some SKF sealed load carrying bearings (full units, no direct axle contact) and they will in no way shape or form be able to come into contact with water or dirt. That design on the Brose motor with the needle bearings against the axle and poor seals is honestly 100% shit. Hard to believe something like that came out of a 26000 employee 100 year old German company.
Actually it's probably planned obsolescence. Industries of that size usually have an entire division dedicated to programming the end of life of products.
18:52 The 20 20 belt "All greased up". What are you refering to with 20-20 belt and what do you mean by "All greased up" ? I thought these belts didn't require any lubricant . Can you explain this please? Btw the video lesson is well done and Thank you !
The belt was upgraded in the year 2020, it has now been upgraded again in 2022. If the belt is a carbon belt, it should be lubricated "greased up" with "technical Vaseline" This will not be true for the new Polymer belts, but you won't be seeing these just yet.
hi what did brose fix on the 2022 new mag motors and what would your upgrades be for that motor? I'm just about to buy a new specialized and i want the motor to be perfect from new thanks
Brose constantly change small items or software and the 2.1 motor had several very small changes, this was then called the 2.2. It will have the upgraded drive belt, but that's all that we know of at this time 17/05/22
My motor just received two more years of warranty,, and two days ago it broke last time they just switched the motor now I'll guess they will change the belt and the belt tensioner and it will be just as good or bad as it was which is the reason why it got broken.. I wish I could send it to performance line bearings instead of brose fixing or switching it.. also I wish if I did send it to PLB that they would make the belt stronger and the tensioner stronger so it doesn't happen every fucking year.. I'm pissed off i saved hard for 18months to get a good EMTB it wasn't easy for me, I'm not a rich Guy my job is to bicycle and deliever stuff in Mountainous Norway I need a good bike and every day it's broken i lose money
Hi. I’ve just bought a 2022 Levo. Will it still need these upgrades or did Brose sold the issues ? Thanks
As of 11/04/2023 the problem is still there, so the upgrade will help.
@@Ebikemotorcentre ok. Thanks for your reply.
The upgrade fixes most of the main issues. Being a 2020 motor, it will not require a new drive belt as it will have the latest polymer belt fitted. It won't be water resistant or have the upgraded sprag bearings though.
Excellent info.. Peter what's the cost for the upgrade service please
Hi, because costs change over time I can't put them here unfortunately, but you will find them on our site here: www.performancelinebearings.com/brose-motor-upgrade-service/
@@Ebikemotorcentre hi Peter, thanks for that...
Great video. Really appreciate you sharing your knowledge 👍
Should we put some Molykote PG-75 on plastic planetary gears? If so how much ? Thank you
Great informative video. I own a 2019 Specialized Levo Turbo Comp with 600 miles on the motor. I don’t ride in water, and don’t pressure wash the bike. I’m not experiencing any issues at this time, so I’m thinking “prevention.” Would you recommend that I make a motor upgrade to ensure reliable service? Thank you from Southern California.
Normally I would say yes, but due to the issues with the 2019 motor, Specialized gave a 4 year warranty just on this year of motor, so by upgrading (although it makes it last longer) it will void your warranty.
@@Ebikemotorcentre ok, thank you. When the motor warranty expires, I will definitely give you my business.
I have the 2021 turbo levo comp…question when did they upgrade the belt? So far with about 1000 miles of mostly all trail riding I have had no problems, I do try to be “kind” to my expensive bike. Really do love how this bike rides and hope if I ever need motor service it can be fixed.
Brose have done a few belt upgrades recently, each one better than the last. In 2020 they started fitting the first real upgrade, then in 2021 it was modified again. These belts were all carbon fibre, but the last upgrade in 2022 they have just fitted a Polymer belt.
@@Ebikemotorcentre Is the new Polymer belt a cost-saving downgrade from the carbon fibre belts? Are you expecting more repairs of the Polymer belts in the future?
@@bradarmstrong1656 No, the polymer belt was an expensive upgrade for Brose and still had carbon strands like the original. It seems to be working well so far.
Hello Peter. I made some comments about a year ago. After 4 years of owning and a lot of Emtb riding including beach exploring water ingress mainly from washing is the killer. My conclusion is all ebike motors need a tiny computer fan within the main frame to slightly pressurise the casing while riding and washing to repel moisture and even dry out any moisture sucked in by heating and cooling. It's the only solution to the problem but are any of the motor companies smart enough to see this or are they too preoccupied with developing more problematic motors and rushing them out without proper reliability testing. What did Brose know in 2018 with the Near SILENT ,powerful 90nm ,smooth Aluminium 1.3 motor that they don't know now 🤔. Add your X rings, upgraded sprag bearing ,belt and firmware and hose vents with a mini fan you couldn't get better. But what would I know. Cheers Rob Haskins E=Mtb²
RELIABILITY and SILENCE are GOLDEN.
Hi Rob, We did look at this positive air pressure solution some time ago, but after some debate decided to drop the idea in regards of a retrospective kit. We also found that after 3 years now, we have had no Brose motors back with water ingress! We seemed to have managed the impossible, 4 layers of sealing, with almost zero added friction!
@@Ebikemotorcentre Thanks for the reply I'm impressed that you replied to a comment on a old video.
Glad to hear the X rings and other sealing is working. Your Australian agent Paul Moir has rebuilt a 2018 1.3 motor for me and all good so far. We have two brose 2018 levo's one 2020 levo and a 2018 shimano E8000 Merida. I have also hired Bosch and lightweight Orbea Rise carbon with 60nm shimano Ep8 but the bottom line is that when I go back to the 2018 Levo the motor is simply the best 👌 ever. Near SILENT, powerful, smooth and the FEELING is "it's me but younger and faster" and now you've been able to add reliability it's even better. Again What did they know in 2018 that they all don't know now.?
At 61 kg and 67 years I prefer a heavier bike for Stability and not really interested in a lightweight emtb for Flickability .
If carbon was any good they would make aluminium from it and if aluminium was any good they would make steel from it. 😁😁 Just a few of my Observations and not necessarily right .Cheers Rob E=Mtb²
Keep up the good work. You and Paul Moir are the only people I know capable of working on and inventing SOLUTIONS to the PROBLEMS that the mtb designers are "dreaming " up without proper testing.
Are they just enthusiasts who like me, just smart enough to be dangerous.🤔😁
@@robhaskins3068 Good question 🤔😊
my motor (levo gen3) failed after ~3500km (10 months). replaced under warranty. but the next time I can be less lucky. probably the belt was completetly stripped.
Should I repair (send to You for example) my motor when it fails ? or is it better to do periodical inspections/maintanance ? and at what intervals (kms) ?
and what is typical service price ?
There is definitely an advantage in sending a motor to us, or one of our worldwide partners because then it can then be upgraded to help stop some of these issues. And we also apply our own 12 month warranty. These motors are not really designed to be stripped and inspected on a regular basis, so this is best done externally by getting to know how your motor feels and sounds when it's new. This is done by removing the chain from the front chainring and rotating the crankshaft by hand, if the crankshaft starts to feel tighter or sound rough etc. then it's time to get it looked at. Prices and explanations can be found here: www.ebikemotorcentre.com/repair-overhaul-service/
I had my Vado SL 2022 motor already replaced once under warranty and I feel like it's already beginning to act funky again almost a year after it was replaced. To be honest I am a HEAVY user, I am out on it day in day out. Now my bike is out of warranty, it might be time to send it in for an upgrade. However I am in Japan :(
We do have partners in Indonesia and Australia, I think they are currently the closest.
Are the 2023 brose motors any better built or do they have the same issues? Many thanks.
Yes, Brose are continually making small changes and updates to their motors and they now have our lip seal added. Stronger, more durable planetary gears and more durable belt pulleys.
Hello! Very illustrative and complete video. I would like to buy the seal at an industrial supply store that you mention at 11:26. What reference is Hello! Very illustrative and complete video. I would like to buy the seal at an industrial supply store that you mention at 11:26. What reference is it??

My smag motor seems to be acting like a normal bike when pedaling back wards, sprocket, chain and freehub will reverse
This happens when your crankshaft needle roller bearing starts to seize to the crankshaft. Unfortunately, it is now just damaging the crankshaft bearing surface so usually better fixed sooner than later.
Hi any idea whats problem i do have brose S motor cut every so often have to turn it off then on to make it works again while motor cut still show speed correctly no errors on display only once error 26 ever
Hi, This sort of issue is usually a wiring or plug connection issue. It may also be the TCU if you have one? I would look at all plugs terminals and wires to see if the issue is visible first.
Greetings from Brazil. What is the diference between the motors brose 2.1 and 2.2 from turbo levos?
There was no big upgrade when the motor changed from 2.1 to 2.2. Brose are continually upgrading and updating components within their motors and there came a time when the 2.1 had received so many little updates that it was changed to the 2.2 and the 2.2 is still evolving to one day become the 2.3
@@Ebikemotorcentre thank you
Why are some mag motors so noisey compared to others.mines always been noisey but noW got 4000 miles on it.Others seem silent.
Great question! We test a great many motors here and the noise can vary from totally silent to quite annoying. The noise usually comes from the planetary gear area and is usually just a manufacturing issue. Sometimes a moulding issue, sometimes a bad bearing from new etc. Some of the early S-Mag motors had an issue where the belt would rub on the motor housing inside. We can now replace this end of the motor, but it is an expensive and risky operation. Not really recommended.
My Son have now the 3 Engine Crash .The Engine is from 23.04 2020 ! The Bike is from Oktober 2019 the first Engine hold 800 KM 2 Engine hold 800Km and now the 3 Engine 3000 Km
Sounds familiar, this is why we upgrade the motor.
I have a Turbo Vado 3.0 (2022) and was wondering if any knows if the motor has nylon gears or all medal? Thanks.
Your motor is identical to the one in this video. It does have plastic planetary gears and a plastic ring gear. The gears themselves do not usually cause any issue.
Is there anyone in the UK that does this? I couldn’t see a UK link.
We are based in the UK! www.ebikemotorcentre.com is our address. You will find our UK contact details on the 'contact us' page. :)
i just bought a vado 4.0. id like to do some of these upgrades before it fails. do you sell a kit of these parts? i have tools for dana/Chrysler drive line rebuilds so i suspect i have all the tools needed for this job.
We don't currently sell this kit I am sorry to say. As you mentioned Dana/Chrysler, If you are in the US, email our American partner Michael maybe able to help: info@ebikemotorrepair.com
After putting it together do you need to reset the motor or something? I changed a broken belt and now the motor wont run.
No, the motor should be fine. Are the clutch bearings the right way round? Check, very carefully the wiring and plugs. If you removed the torque sensor pick-up or the ECU, did the two sensor plug pins go back in properly?
Hi, I bought a 2021 Levo HT 2 months ago, my son borrowed my bike today and on his return I noticed paint missing on the drive side crank arm end near the pedal, he told me that it happened while he was walking the bike over some rocky terrain, now when I back pedal the bike I noticed a slight rough sound where previously my bike had been completely silent back pedalling, do you think I should have this looked at by my local specialized shop as it sounds to me that I might have damaged sprag bearings, although you mention in this video that my 2021 model has been upgraded already? So maybe its water ingress on the needle roller bearing as I do not have any issue pedalling forward and everything is perfectly smooth riding the bike. I have been using the bike in very wet conditions and have washed the bike over 6 times now but always careful with low pressure hose. Any advice would be great appreciated with what bearing you think might be causing the sound. regards, Paul.
Firstly, I don't think this is anything your son has done. This sounds typical of needle roller bearing failure due to water ingress, you should be entitled to a new motor under warranty. Although your motor is 2021 the new type sprag bearings can still fail, but you won't feel this by turning the cranks, you just won't move forward so think these are fine.
@@Ebikemotorcentre Many thanks for your reply, I thought it might be more water ingress and did tell my son not to worry, he has his own levo arriving next week so hopefully we'll be more successful in keeping the water out of his bike, thanks again.
Great video! Very interesting to see your upgrades 👍

I opened my electric unit side and now motor not start in all, any way to fix this mistake?
If you have removed the electronic control unit (ECU) it is possible that the two small pins that send information from the torque sensor ring to the ECU are not aligned properly. This must be done extremely carefully.

I question how the product managers and engineers dont consider the application of the product. Both spesh and brose have done a shoddy job in places. That early motor with no seal. Like what!? Its going on a bike! How can they not consider wet westher
When I made this video, I did not want to point out any weakness of any one motor. These are very early years in the eBike world, and ALL motors have their week points and issues.
I am not defending the motor manufacturers, but don't lose sight that these motors were originally designed for the European road bike market. As a road bike motor they don't tend to suffer repeated pedal strikes, pressure washers, deep water, mud, grit, bull dust, 30 ft jumps, rocks, tree roots, etc. etc.
I believe it was the bike manufacturers that started using them in mtb's when Moustache first fitted a Bosch classic into one of their mountain bikes. I don’t say that the motor manufacturers were not to blame as they would not be blind to the fact their motors were being fitted to mtb’s. But, in manufacturing terms, this only happened yesterday. To scrap a product run before it has started paying you back is not great business sense. To fit a seal that creates friction and makes your bike look bad on battery range against your competitor is also commercial suicide. Any sizable company with due diligence will normally spend 4 to 5 years before releasing millions of new motors all over the world too. (I know, I used to be involved in this process).
There are a million and one other things to consider but my one finger typing skills don't afford me the time to discuss everything. Please rest assured, the manufacturers are aware, and they are working on it. Change is coming and I will probably be out of business in the near future.
Also helps to know there are millions of motors out there working happily after thousands and thousands of miles…
Remember when you would get off your normal bike and carry it through the mud because you could no longer pedal the thing! And now you use your eBike as a tractor. I know, I do the same and its great fun, but I bet the manufacturers never saw things like that coming!
Hello, is there a chance that you will make video how to change bearings on Shimano motors? Can you deal also with Shimano motors?
No sorry, We used to overhaul Shimano motors but don't currently due to the inherent software issues on the E7 and 8000 models
Do you happen to have a sizing or bearing number for the Needle Roller bearing?
Yes! You can buy these from our site here: www.ebikemotorcentre.com/brose-bearings/ Or if outside the UK one of our partners here: www.ebikemotorcentre.com/where-to-buy/
I Have 3 brose and a Shimano E8000. You really know your stuff. Is the Shimano better sealed .Do any brands have a breather and moisture absorbing silica. All hot encased components will suck in water thru seals if cooled quickly submerged in water. E=Mtb²
Yes, Yamaha have a small breathable membrane but that's the only motor I know of?
@@Ebikemotorcentre Thanks for the reply. Our two 2018 1.3 and 2020 2.1 are a bit rough when I spin the cranks backwards but have been spraying Inox on outside of bearings with bike lying on its side . The Shimano E8000 motor is smooth As and must be better sealed.
@@robhaskins3068 Do yourself a favour and stop spraying stuff into the bearings. The oil masks the problem but goes through into the motor and this is not designed to have oil in it! It can cause issues with the clutch bearings, belt and ecu. It also takes hours to clean it all out because it gets everywhere! The Shimano is sealed with lip seals that help, but unfortunately, to cut down on friction these are extremely small and soft, they normally let water and grit into the open needle roller bearings that sit directly behind them. I am glad your's is still ok.
@@Ebikemotorcentre Thanks for the tips. The sealing or breathing of motors must surely be a major design issue all manufacturers can work on next. I think the very best Emtb motor is the most Reliable and only time will be the decider. E=Mtb²
I have a 2017 sworks levo with creaking noise on hard pedal everytime. How can i contact you to fix mine. Thanks
Creak is not normally the motor. Check motor bolts, crank bolts, pedals, chainring to spider bolts, seat post, rear shock or linkage bolts, rear axle, spokes etc. etc. Bearings don't creak :)
Thank you for showing the ins and outs of these motors.
I was wondering if there may be pressure differences from a hot motor being presented with water that may cause ingress of moisture due to the effects of sudden cooling.
This is a scenario that we have thought about many times, even to the point of considering fitting a small air pump to keep positive pressure in the motor. But that would just consume power and may introduce damp air into a sealed system. I feel that with the limited space and small air quantity within a motor, coupled with the relatively low temperatures they run at and brief period of time they should be submerged for (not that they should be submerged at all), pressure differential issues should not be a big issue. We are still looking at this scenario though and when I have time I will heat a motor and drop it in the sink for a few seconds, just to see.
I’m wondering if this is a useful upgrade in terms of reliability of my first version brose 161. my first one died electrically after around 2000km but I bought the bike used and warranty was denied from the bike shop. my second one is now slipping when pedaling. I am a little unsure if the upgrade with the new clutch bearing will fix the slipping.
This upgrades only purpose is to increase reliability. As we replace both clutch bearings with heavy duty versions and a thicker drive belt, this will fix any slipping.
@@Ebikemotorcentre thanks for your quick reply. Then I can only hope that the electronics will not fail soon - or buy a new bike. Cheers
@@CarlosGlatzos976 Once we seal the ECU and treat the power and switch plugs, there should be no electrical issues :)

How can you tell what Gen motor you have, please? I'm looking at buying a 2016 BH Emotion Revo Cross that has come up for sale.
Brose tend to equate part numbers to their motor series, they don't really tend to have Generations like Bosch for example. But guessing by the fact that your bike is an early gravel bike, I would think it has a 1.2 Brose motor in it. 1.2 is still made today and it just means that it is a 70Nm motor.
@@Ebikemotorcentre @Performance Line Bearings Thank you for your video and fast reply, love your work! The 2016 BH Emotion Revo Cross is a hybrid bike and I have reason to believe the motor is a 2.0. I am wondering if there is a recommended time/mileage for replacing the carbon belt, as is done with timing belts in cars, replace every 100,000ks or so, and is there any way to check the motor for possible wear like excessive free play or noise for example other than doing a full tear down? Getting back to the video, what did you end up doing with the worn crankshaft, new or re-sleeved, and how tight do you make the preload on the carbon belt? Cheers.
@@slavojalois1639 Brose recommend changing the drive belt every 15,000km. We replace most worn crankshafts with new ones. To check your bearings, remove the chain from the front chainring and feel the crankshaft. There should be no play up and down or in and out, the crankshaft should turn very free, quietly and feel silky smooth. This can sometimes be masked by the bearing layout in the crankshaft, so spin the pedals by hand and listen for a roughness or feeling when the crankshaft comes to the bottom of its stroke and there is some weight applied by your hand. The drive belt pre-load is currently 0.2Nm (This is critical, do not try to guess it).
@@slavojalois1639 Bosch recommend belt change at 15,000km. Check motor by removing chain from front sprocket and spinning crank by hand. The crank should spin freely back and forth with no drag on the front sprocket. Crank should sound silent with no horizontal or lateral play. We normally fit new crankshafts if they are badly damaged. 0.2Nm is the belt tension. Lubricate with Vaseline. 👍
Is it worth having the upgrades done on my 2020 levo it currently has no issues with only 200 miles an has years left on warranty?
This is a good question! Currently, if we upgrade your motor and make it last longer, you will lose your warranty! This is still important because although we issue a 12 months parts and labour warranty we only cover our parts or any fault of ours while fixing your motor. So, if for example, we upgraded your motor and your ECU (motor brain) fails, you will be liable for a new motor. The annoying thing is, if your motor does last until the end of the manufacturers warranty and you have used it off road, it will be ruined inside.
@@Ebikemotorcentre when you have done your work on the motors have they been lasting or still having problems ?
@@adamdoyley7017 We have not had one back yet and we have a fair few out there now! There are 6 or 7 week points on this motor and two main ones we can't currently fix, so we can't promise you won't be walking home one day.

what a mess @ Brose. Engineered to fail within 4 years !? (I thought german engineers should perform better...) Thanks to Performance Line Bearings to have a solution to fix the problems !
Jesus...all the tech involved in these motors gives me pause worrying about what can go wrong with an eBike! Especially the apparently poorly designed tech! The idea that the earlier Brose motors had little or no sealing is laughable! For a product that is designed to operate in foul weather conditions...dirt, dust, muck and water...having the entire moto assembly/circuit board unprotected points to some pretty bad design! And the engineers should have known that the plastic housing/spacers on the sprag bearing were an obvious item that would fail under the loads of an eBike! I'm curious...are Brose/Specialized/Bulls paying for these upgrades as some kind of a recall scheme, or is it on the consumer to have to pay to correct the design flaws?
Bro, I think you very much have completely disregarded the fact that the whole genre of biking known as ebiking is still very much in its infancy.... it’s less than 10 years old. Answer me this - how long did it take for us to get from the Ford Model T to the types of cars we consider now to be “modern”?
@@jonathanweston2448 Oh, come on...we’re not talking about inventing new technology. Sealing an electric motor from the elements you know it will encounter during regular use is engineering 101. Producing a bearing system that would hold up under the expected loads these bikes were going to produce should have been anticipated, especially considering the weights of these new bikes. These are simply examples of sloppy industrial design. And if these companies have the balls to charge what they’re charging for eBikes, then they can take the criticism!
@@jonathanweston2448 The manufacturers should certainly cover the cost of 'upgrade' via a recall, if they are as 'crap' as they appear without modification.
Rest assured the motor manufacturers are doing what they can on the latest motors to start helping this issue. It is easy to lose sight that these motors were designed for their main market of road bikes and as a road bike motor they are superb! However, when the industry started fitting them to mountain bikes, the motor manufacturers must have been in on that decision. But these are big companies that cannot react quickly but as I said, they are reacting and motors will become more suitable. It is also harder than you think, to seal a motor without friction. It would be commercial suicide to release a motor that does 1 mile less range on the same sized battery as your competitor!
Outdoorsman well..... mines on over 2500miles, is a 2019, and I’ve ridden and raced it..... still perfect!
Brose hätte Sie als Entwickler gebraucht.! Ich habe nun den Brose 2.2 und noch mehr Probleme ( Fertigungstoleranzen ) alles schleift.
Stimmt, sie scheinen uns oft zu kopieren :)
Do you guys still have a shop here in America??
Yes, you can find the link here: www.performancelinebearings.com/american-supplier/
@@Ebikemotorcentre oh that’s great!
I’ve got one of the rare Brose motors in a 2019 Kenevo that’s been totally trouble free. The motor is derestricted and frankly rocks!! I do not want a new bike and would prefer to send my motor off this winter, before anything happens.
This rebuild, it appears, would NOT effect my derestriction, right?
@@dag681 No, this will not affect any de-restriction 👍
Brose Motors appear to have some basic design flaws with water proofing. Given the price of the bikes and ultimatly the motor they should be rectified at the manufacturers expence. The sprag bearings too look like a case of cheapskate on the production for the sake of $20-30 they put owners of these bikes through a whole lot of needless grief.
What is the R&D for the extra seals and the uprated sprag bearings done by yourself or third-party
Brose are using these sprag bearings and belts in their 2021 motors, and they have done enough R&D for everyone. We have had the seals out in the field for over a year now. We chose a lot of people who gave us the worst and most abused motors and fitted them with seals and upgrades to test for us. Also we have our own Brose, Yamaha, Bosch and Impulse test bikes to do our own work. Please remember, we do not state that this motor is "waterproof". To water proof these motors would create too much friction. We have used a solution that causes absolute minimal drag or friction and helps with keeping a majority of water out. Ride through a flood, ford deep water or pressure wash your bike and you will still destroy it.
@@Ebikemotorcentre that’s good to know that new parts are backwards compatible to older models.
Thank you for the reply I was just interested.
Engineer by trade so my brain never stops 😂 allays seeking improvements
Do you repair broise motors?
Yes, you can find out all about our repair service and prices here: www.performancelinebearings.com/ebike-repair-overhaul-service/
Do you service motors from the USA?
Yes, we have our man in the US his details can be found here: www.performancelinebearings.com/new-american-supplier/
@@Ebikemotorcentre thanks for posting that link.
So, it means that whit this new upgrade can we fit standard bearings like BlueSeal, SKF, NTN without the outer seal on the cases?
No, Sadly, no bearing is water tight and water will get past the seals. The standard bearings are of excellent quality too. You will not find the right hand crankshaft bearing, it's a custom size and finally the rubber lip built into the unique Brose bearing seal is used to stop the bearing rotating in the casings.
ASs we state on our site, "adding these seals make the motor as watertight as is currently possible" It does not mean that your motor will be waterproof! If the motor was sealed to be waterproof, the friction would probably knock 30% off your battery range.
@@Ebikemotorcentre Thanks for the answer, I'm asking because on the vid your BlueSeal bearings look like a "standard" bearing reinforce whit the xrings on the outside, my local bearings dealer have the right hand crank by order but without the seal (unknown brand/ price), Ill guess I have to order the two outers from you.
@@R.Rodrigues You're right! The right hand bearing has the designation number 6807 stamped on the seal and you can buy a 6807 bearing anywhere. Unfortunately a standard 6807 bearing has the dimension of 35x47x7mm. However, the Brose bearing, apart from the special seal, has the dimension of 34x47x7mm.
@@Ebikemotorcentre Yes, the 34x47x7, but still waiting for quote and the brand, I'm expecting to be extremely expensive because its custom, that's why I probably will order the two outers from you (sprags are in good shape and minor pitting on axle were the needles work).
What about using sealer on the gasket to ensure beater sealing, I use type 3 aviation gasket on my other hobbys, does not increase width off the gasket, its really good stuff.
Thank's to your vids I'm able to take my motor apart and in the process off making parts in the lathe to press the bearings.
@@R.Rodrigues I would :) To be honest, the only other bearings I have seen in this size are headstock bearings and they have one race chamfered away to fit the forks.
Is there anyone doing this in the US ?
Yes, you can find our US partner here: www.performancelinebearings.com/american-supplier/
a few riders
good grief wouldn't like to try and knock those bearings out with a hammer and socket !! Wonder how many kids out there wish that you were there uncle?.......Look how many times these "road and track testers" were telling you how safe it was to go knee deep through water day in day out.......my yammy motored bike is sitting in the front room with me by the fire
Where can i order this bearings ?
We are trying to get the cost down to make this as a kit, but at the moment it is very difficult with Brexit!
@@Ebikemotorcentre i wuld be happy just to get the two Sprag bearings...
@@villikjartans I know, they will be coming, please bear with us.
It's really shocking that such an old and established company like Brose would use such inferior parts and poor engineering . They knew from the beginning that they would have to compete with the likes of Bosch and Shimano and yet went ahead and dumped an untested
motor on the market . they initially got rave reviews for power and smoothness of ride and then their reputation went into the toilet once these problems showed up . pity .
When I made this video, I did not want to point out any weakness of any one motor. These are very early years in the eBike world, and ALL motors have their week points and issues.
I am not defending the motor manufacturers, but don't lose sight that these motors were originally designed for the European road bike market. And as a road bike motor they don't tend to suffer repeated pedal strikes, pressure washers, deep water, mud, grit, bull dust, 30 ft jumps, rocks, tree roots, etc. etc.
I believe it was the bike manufacturers that started using them in mtb's when Moustache first fitted a Bosch classic into one of their mountain bikes. I don’t say that the motor manufacturers were not to blame as they would not be blind to the fact that their motors were being fitted to mtb’s. But, in manufacturing terms, this only happened yesterday. To scrap a product run before it has started paying you back is not great business sense. To fit a seal that creates friction and makes your bike look bad on battery range against your competitor is also commercial suicide. Any sizable company with due diligence will normally spend 4 to 5 years before releasing millions of new motors all over the world too. (I know, I used to be involved in this process).
There are a million and one other things to consider but my one finger typing skills don't afford me the time to discuss everything. Please rest assured, the manufacturers are aware, and they are working on it. Change is coming and I will probably be out of business in the near future.
There are also millions of motors out there working happily after thousands and thousands of miles…
Remember when you would get off your normal bike and carry it through the mud because you could no longer pedal the thing! And now you use your eBike as a tractor. I know, I do the same and its great fun, but I bet the manufacturers never saw things like that coming!
@@Ebikemotorcentre Fair enough , however Brose glossed over the belt and bearing issues by claiming that the problems had been solved via a software upgrade AND by increasing the warranty on the specialized bikes to four years ,instead of admitting to the real problems and fixing them as quickly as possible . That four year warranty won't do you much good if your bike breaks down in the middle of nowhere .
Even if Brose does manage to fix these problems , the damage to their reputation has been done and to restore it will be a monumental task .
i almost bought a Nox e bike with a brose motor until i heard of the problems . i now have ordered a Nox bike with the new Sachs Rs motor .
So far , after three years there are no reported problems ,,,,,, YET . 😂
wish me luck.
@@siriosstar4789 Definitely can't argue with what you're saying. And wishing you lots of luck too 😎
it's like watching workshop porn....
I wish i had repair shop like yours in my area.
This is very bad design, looks like they dont care about waterproofing things at all. I ride to work whole year, even in heavy rain and snow and that motor would die in one month probably...
Don't worry, these motors are fine in the rain and snow, it's normally deep water crossings, power washers etc. that cause problems and currently, this is the same for 99% of eBike motors on the market. Brose are now adding extra seals and weather protection, so this issue should start to become a thing of the past.
