eBike motors go through a lot for us, we plough down chattery trails and tackle steep climbs and they always provide the power when needed. Although it's not an easy life for eMTB motors there is hope! What if we told you there is a way to make your motor last longer and run quieter? Well... there is, Steve Jones is at the eBike Motor Centre learning how they service motors and install the upgrades they've come up with.

Will you be getting your motor upgraded after watching this video? Let us know in the comments below! 👇
I own a 2019 custom build Bulls twin core with the old Shimano e8000…It was hard to find someone for the Job, all shops suggested a new motor 😢 motor has 11,000 km and just got transmission fixed and new bearings😊 ready for many more adventures, even though I got me a new E-Bike
@@MarioNhampossa so who fixed it?
I would like to buy an upgraded motor for spare, so I don't have any downtime from biking.
Can they repair shimano motors ? Yes, if they can repair a motor, then I will definitely upgrade it.
@@blakkpatron he runs a little online shop with used motors and repairs them, I’ll ask if it’s okay to mention him in here
It's fantastic to know these places exist and it gives an element of comfort knowing that if you do have a motor issue out of warranty it is not the end of your prized possession.
In a time when the bike industry is suffering as we all have less spare cash to buy the shiny new expensive models and instead we want to keep our older and beloved bikes going longer this is brilliant. Like with third party companies making parts for cars we need this 'repair rather than dump' ecosystem to expand in the emtb world. And the bike industry needs to take note and make it easier for third party companies to do this to the motors rather than landfill. More of this content please EMBN! Time as well maybe to do some more films on the home kit build area like that engineer fella who built up his own bikes in Wales you covered a while back - and see what are the new developments going on there with any new motors, batteries etc.
I had my 2019 levo motor this upgrade carried out there after the 4 year warranty expired. I was one of the lucky owners that didn't have a motor fail throughout the preceding time. I took the motor in myself and collected when ready, which turned out to be quicker than initially advised. I chose to have it carried out for preventative reasons after watching some of the eBike Motor Centre's own videos on this upgrade. When I collected the motor it was returned to me by the owner of the company, Pete Collard. I was/am extremely impressed with the whole experience and setup and certainly enjoyed to last bit of the journey in through part of The New Forest
My motor is with them as we speak! It could be one of those on the shelf next to them. 😀
Pete did an excellent job with the mechanical restoration of the motor, which is easy to maintain as long as we have access to outsourced spare parts. However, the most critical and challenging aspect to maintain or replace is the motor controller and other electronics housed within the motor case. These components are proprietary, and if the manufacturer decides to discontinue production or stop selling spare parts, we are left with a non-functional motor. This practice should be prohibited, but unfortunately, we consumers have allowed it. My recommendation, which is our only viable option, is to purchase a second motor for spare parts. Additionally, it's crucial to identify the types of SMDs used on the PCB and secure any available components for future PCB repairs. To enhance the controller's protection, apply a high-performance waterproof conformal coating, such as silicone or ceramic, and use a superhydrophobic coating on the PCB and inside the motor case. This will significantly improve the water resistance and extend the overall lifespan of the motor. Please remember this: while mechanical parts are easy to replace and maintain, proprietary electronics are NOT.
Yes very true. I did have a spare rebuilt motor for 2 years but when I finally fitted it went to 93⁰c in 2.5 km with little power. Something definitely wrong with the windings .Mechanical it was fine. My idea to keep the moisture out is to fit a mini computer fan to provide positive air flow from a breather up at the steering head and add a bag of moisture attracting crystals .
@@robhaskins3068 how bout to have a humidity sensor inside the motor? they are really small, for example i use the "Aeotec - 6 in 1 Multisensor" you have a heat sensor, humidity sensor, fire sensor, smoke sensor, motion sensor, light sensor, and vibration sensor. also a good idea would be using a small pump (button that you press with your thumb) to can generate positive pressure inside the motor case.
@@Almajtek Humidity sensor would be a great idea as you or it could turn on a fan to dry the moisture before the bearings go rusty. It's not the electric motor but the bearings that are the problem. Circuit boards should be available as spare parts. Replacing a belt on a Brose is incredibly easy. Thousands of brose motors have been thrown out simply with broken belts. Sprag bearings are always going to give trouble from massive forces from big pedal strikes. It's like smashing the end of the crank arm with a massive sledgehammer. I recommend 150mm (shorter )cranks and 170mm Fox 38's forks with 29x3.0 front tyre and a 27.5 x3.0 or even 3.25 rear tyre .This gives great ground clearance and brilliant smooth fast ride through the rock gardens and is much easier on your body. It's a bit like when someone first rides a Emtb. It's a revelation but the tribe mentally will not be prepared to try it. E=Mtb²
I met Pete yesterday in a pub. What a nice man. I will be using him when the time comes for upgrade
He didn't buy me a pint though 😂😂
This is the elephant in the room. Right to repair. It’s befuddling that most motors are so vulnerable to the elements
The major brands in the EMTB scene have everything proprietary and it's a joke. Only company not doing this Bafang.
After warranty’s expired, motors can be opened and repaired. Not by everybody, though.
Great to see the mechanic' s eye view and talking us through the repair .
Excellent! I previously complained because we were left with just comments of it could be waterproofed with "magic", so this is a great follow up to that. Thanks again.
Great article EMBN.
This is awesome. Living in a rainy place like Iceland these kinds of upgrades would greatly improve the longevity of motors. I just wish the manufacturers would allow these upgrades done while the motors are under warranty. Good bike shops should be allowed to service these given the proper tools and experience.
We do have a partner in Iceland, that would be happy to help you.
Nice to know somewhere to go for motor problems,I couldn’t do it my self ,got sausage fingers😊
Pete's eBike Motor Centre will be my savour when my motor inevitably goes. Until then I'll do everything I can to keep the water out :)
U can keep the water out but not the dust & dirt.
I live in the desert, so water will not be an issue. But that belt looked ragged out, YIKES!
Reuse and repair for the win.
I'll be giving them a call this week. Am currently waiting on my second replacement on my brose mag s and this one is the last one in warranty, so i want it to last. The last one went out of warranty in Feb but Specialized still covered it 100% which is pretty fair, especially since it didn't fail but just started to have a very slight squeak which was a telltale sign of water ingress But the new one is getting better waterproofing from day 1! Thanks for the video, Loving this info!
Impressive attention to detail. I can attest to their workmanship, having had my Bosch Gen 4 serviced recently, now running like new again. Thanks guys! 👍🏻
How many miles/kms did you have on the Bosch? Did a specific event cause it or just gradual water ingress as usual?
@@vashon100 I don’t think it was water ingress, it was a bearing replacement that was undertaken. I bought the bike 2nd hand so am unaware if it’s full history, but I live near a large forest and don’t bother going when it’s wet, nor do I ride in gloop or through watercourses, etc. There’s about 1100 miles on the odometer.
Great job, if theses guys can do it, why can't the manufacturers sort it in the first place. !!
For the same reason why Mercedes could make cars last forever 40 years ago, and nowdays they "can not".
This reminds me of when Trigger got a medal for having the same broom for 20 years… and in that time it had 17 new heads and 14 new handles! Lovely jubbly
The original Brose in my 2019 Levo was replaced under warranty after it became VERY noisy. That was about 4 years ago. Last autumn, the replacement Brose exhibited most of the failing sprag clutch symptoms. The bike was barely ridable. I had the motor rebuilt with upgraded parts by eBike Motor Centre's United States affiliate. It was very expensive, about the same as buying a new motor, but my hope is that my rebuilt/upgraded motor will last longer than a new one.
That's unfortunate it was not cheaper than buying new. In theory it should last longer than new, but unless everything needed to be replaced, it should have been cheaper.
Excellent video. Thx.
Absolutely brilliant video. keep it up.
Remember fellow ebikes riders, never power wash near your motor, first cause by far of e bike motor damage waterproof doesn't mean it can handle pressure washing
Should we lick of the mud instead? Bite size kisses till it’s all clean? C’mon… if you can’t hose it down it’s junk… It should fine even if u dump the whole thing in wet sloppy mud.
Really impressive work there
Great video. Thanks😊
We have 4 Specialized in our family with 5 broken belts - the new version of the belt are still working
Nice job.
Amazing and very useful information
great video
Thanks!
Awesome💚💚
Definitely the best video for the ebike community, the motorbrands need to move towards or should I say back to easier servicibility. The one thing that bikers fear the most is not to be able to ride.
This is a good video with good information regarding waterproofing. Picking up my new 4k e bike on the 2nd of may good to know if any water damage can turn to these people
I've had my mountain ebike which has a Bosch Gen 4 CX motor for 4 years which I admit hasnt been service and still works (touch wood 🤞😂) and have often thought about getting serviced to keep it running for years to come - this episode convinced me that it would be a great idea as my bike also works really well for me and have had many years of fun exploring Scotland and its trails on it, very informative thank you for sharing! 😁👍
🙄🙄
You little beauty I had a Levo base model 27.5 back in 2019 great bike didn't really think much of the Ergos being a similar type bike to the Stumpjumper the low end forks were rubbish and no upgrade damper available I upgraded the wheels to Nexti Carbon 45s and the forks to Cane Creek Helms it was a sweet ride. I upgraded the bike eventually to a 2020 Norco Sight E-MTB VLT2 720wh with much better trail mannerisms to the Levo be great to see A REBUILD VID ON THE SHIMANO E8000 MOTOR a fine bit of kit that motor no dramas so far highly recommend the Norco ❤ cheers mate Happy Trails
lol, me old faithful never let me down. Proceeds to get motor upgraded.
Everyone that I personally know that has had a Specialized ebike has had to have the motor replaced at least once. So it seems to me, the best way to extend the life of your ebike motor is to NOT buy Specialized.
... or to have it inspected and upgraded, just after the warranty expires 😉👍 Greatings from Austria
Currently on 2000miles on my original motor fitted to my 2021 Kenevo. My mrs Levo has also had no issues. We have maybe just been lucky.
@@lakedistrictmatt1641my bosch also still works fine
1000 kilometers on my 22 Levo and it's still amazing.
Thank you so much for this video. I have 2 years on my motor warranty. But I'm already planning on having a unit fitted like this from the American company that does this. I'd love to ship to the UK but I'd be worried we'd lose the engine in shipping.
Amazing how companies like this are taking it upon themselves to make improvements towards longevity like this and the manufacturer's only seem concered with more power or being lightweight. When my Shimano motor is out of warranty i'll hopefully bin it (first one failed after 460 miles) and get something that can be worked on and improved when out of warranty.
nice! is it any chance for similar video but with bosch and shimano motors?
Wow!! Would love to have my 2019 Specialized Turbo Levo Brose motor upgraded here in the US. Any recommendations of a shop in Southern California?
My wife and I both have levo's, her's is a turbo levo and mine the SL. Just how much would an upgrade like this cost on a still functioning motor that didn't need any other work, and do they offer something like this for the 1.1 SL motor as well? Live in Alaska and not fair weather riders but would love to take these bikes out in the inclement weather and enjoy them.
Any where in Australia that offers this service?
Pete knows his shit
I’ll be shipping my Bosch to them when it’s time.wonder what the shipping will be from newyork to them?
If you are lucky enough to have a 2018 1.3 brose Aluminium motor get it rebuilt and you will have the Quietest, smoothest most natural feeling, powerful motor ever made.The upgraded needs importantly the 2 extenal X or Quad rings inside the crank arms to keep moisture out. The Aluminium 1.3 motor is far better in every respect (including software)than the later magnesium motors. But what would I know. E=Mtb²
The early brose motors are terrible for water ingress, should have been recalled and fixed. barely last a few year! I had my motor refurbed by these guys and it's been solid ever since, and they offer a guarantee which says a lot.
Really good point about the recall idea.
Who's their service agent in Australia?
Fantastic video, thank You! I just have a few questions: If the planetary gears or something inside that hole (bearing, gear, rotor) fails in a Brose motor, that means it must have a new case with the electric motor and planetary gear? What is the best grease for the planetary gears to be the most silent? When You torque the belt tensioner screw, You only torque it once with 0,2 Nn , or (this is how i do) i spin the spider schaft backwards than i re torque the screw with 0,2 Nm once more, and the screw turns like another half turn? Thank You very much! (a Specialized bike fan :)
We have developed a tool to change the planetary gear, so this part is now totally repairable, without changing the case or ECU. We use Molykote EM50-L on the planetary gears, it's much quieter than the original grease. I used to back the motor off and re-tension the belt, but we found the planetary gear support bearing was failing prematurely, so we now torque the belt exactly the same as it is done in the factory. I hope this answers your questions.
@@Ebikemotorcentre Thank You very-very much for the answer!
so what where causes of the failure of the brose motor shown? is it just the water or others? bearings look really bad.
I'd love to send my ebike motor in to have it waterproofed and overhauled as necessary but it's a Shimano motor and it seemed you implied in another motor video that Shimano doesn't want third parties working on their motors. Is that true? Thanks for the informative videos. Steve you are the best.
Top drawer engineering skills Pete! Love the belt 'n' braces upgrade. Do you service and upgrade the Bafang M510. Also, are you able to express an opinion on the design and durability of the M510? Great vid Steve!
No Bafang yet unfortunately. As soon as the numbers get a bit higher in the UK we hope to be able to support their owners if needed.
OK, many thanks!
Hello! Greetings from Brasil! I have a turbo levo comp with 2.2 motor and i want buy a turbo levo expert 2021 with the motor 2.1. But I saw many riders talking about some problems of the motor Brsoe 2.1. What you say to me? I make the change or stay with my turbo levo comp?
Good luck finding a local repair shop mechanic able to do this type of service.
Best to use a specialist location for this stuff. Similar to how suspension service centres take care of suspension.
are there shops like this in the US?
i currently have a 2021 levo with the 2.1 motor, if in the future when it goes can i replace it with the 2.2 or will the software be different?
No, it will still currently work and the software won't affect a 2.2 motor in your bike.
6000+ miles on my Bosch center drive😊
Great video! This is precisely why I will NEVER buy another shimano motor bike. Non serviceable due to risk of E010
Would be great to know aprox. How much this operation costs
Anyone knows some, same quality/reliable addresses on the old continent?
Great video! Is there a place in South Africa that can do this?
That might require a bit of localised searching we're afraid! Maybe check in with local bike shops as a starter :)
Do a bike Check with Ady Nash and his Levo. Keen to know about the bare aluminum process
It’s a shame that the manufacturers couldn’t take the time and effort that the team at the Ebike Motor Centre do in upgrading and making a good product better and ‘fit for purpose’. As Steve points out on a few of these videos - you can be reassured that your motor is repairable but more importantly, at a reasonable cost compared with any other area from drive systems through to forks 😎
In this case it did happen! Brose invited us to the factory in Berlin Germany, where we performed this upgrade in front of them. They now fit this seal in their latest motors and asked us to be their new UK Warranty Service centre. There is some more big news coming, but EMBN might want to be the ones to report on this.
Excellent news plus it’s good to hear they value your input, skills and knowledge 😎
Für diese hohen Preise die ein E Mountainbike kostet müssten die Motoren absolut Dicht sein! Bei den Verbrennern funktioniert das ja auch schon seit einer Ewigkeit, sonst würde überall Öl raus laufen! Ich bin entsetzt! Fahre Bosch CX Gen. 2 und hoffe das er OK ist und bleibt! Seit 7800 KM und 178000 HM bei sehr guter Behandlung und Pflege 😂bisher keine Probleme!
What grease syringe is that?
A great british company @ work i hope that Brose & the other motor brands watch this video & take note. T here’s no excuse for the motors no being waterproof as Ebike motor repaires have just proved.
We're slightly less lucky here in US with repairs and overhauls like that. For instance I have been quoted by eBikeMotorRepair in US that an upgraded overhaul for my Brose S MAG would cost me $863, excluding shipping. Somewhat steep given that a brand new motor through my LBS can be purchase for about $100 more.
I spoke with our American partner Ebike Motor Repair about this, and he was quoting for a full upgrade and full overhaul in one hit. He will be quoting separately now, which makes a lot more sense economically.
Those Brose motors are not designed well. The Shimano EP8/E8000 series never sees this much water ingress. Having a drive belt makes no sense either.
I wish I knew all of this before buying an EMTB, lol.
My Brose motor was gone through and upgraded there just last week.
Did it cost about the same as a new motor (as one other commentor said)?
@@vashon100 No only £272. And that was a left crank bearing replacement as well.
@@vashon100 This was a quote from our American partner, who was quoting for a full upgrade and full overhaul. We did have a word and he will be quoting separately now.
As far as I got this, the motor was not called broken, in the beginning? Did it work before it was opened? I mean, broken belt, broken bearings...!?
The one they worked on was an older motor which had totally failed not the one from Aides bike
Can this be done in Toronto?
It can be done in Canada, we have a Canadian partner who can be found on our "Worldwide Partners" page on our website.
Question: applying the upgraded parts and water proofing, to the motor/housing, is their an additional weight added or removed from the motor from its original weight?
If there is weight added or removed, it would be milligrams. The main importance to us was than no discernible friction was added.
Do they have partners in the US
Buy an old car for less than a mountain bike, reliability will be yours for sure! You may even enjoy the tail end of the 7 year guarantee ! Peter is in the business of repairing mountain bike motors as OEM's appear not use 'O'rings to seal shafts. What's a $2 lawnmower belt doing in that gearbox? Wonder why these units don't have a tap on them to let the water out, hopefully used before the guarantee runs out?
has this shop ever worked on a Sachs/BMZ motor ?
Yes, we have done both these motors. And Oli, Fazua, TQ etc. Unfortunately, it takes an unbelievable effort and cost to support a motor and in the UK, there just aren't enough of them to make this viable yet. Please remember, when you have no assistance from the manufacturer, there are no parts, no manuals, no software. This is why we can't yet support all the motors out there... But we are working on it.
thanks very much for the reply . it does worry me that obscure motors like the Sachs/BMZ motor may one day need repair and there won't be any parts or instructions on how to repair it . the company is very secretive about their motor and won't allow the dealers todo anything on it . all faulty motors ,if any , must be sent to the manufacture for repair and or replacement . BTW Sachs is now owned by the BMZ battery company of Germany . it's not two separate motors
I would like to,
It really looks like most ebike motors are barely fit for purpose. My Yamaha unit is currently being replaced after 1400 miles…
Lucky you. I've got an 9 month old Kona Remote, admittedly with an older E7000 motor but in UK conditions it failed after 460 miles. Its never been jet washed and never been carried on a car (driving rain into it) but it failed due to water ingress and the bearings going as a result. Pretty hard to avoid water during the last 8 or 9 months in the UK..... Agree though, the lack of protection for water is absolutely mind blowing.
I agree, E-Motor manufacturers are producing inferior products, and bike manufacturers don't seem to care and still use them. It's crazy how people don't kick up more of a fuss about it. If an off-road motorcycle engine was letting in water the company would be ruined over night.
The crazy thing is when its debated on forums or YT like this there are always comments about it being new technology, how water protection isn't as important in road bike motors etc and excuses made. But it's not exactly a new issue, it's not really being addressed either as more and more manufacturers keep developing motors which are either more powerful or lighter, rather than more reliable.
Which problem did you encounter?
Even if you don't clean it, the motor heats up during use and, if wet, will draw in water as the air in the motor casing cools
Is there a way to make yamaha motors more waterproof?
Don’t wash them with high pressure.
We have just finished an upgrade kit for the Bosch Gen 4. Yamaha is our next project.
@@Ebikemotorcentre curious to see the Yamaha one!!!
@@Ebikemotorcentre which Yamaha motor?
@@stuka78 We will do as many models as possible.
I'm really interested in this very timely video, but it's a struggle to watch I'm afraid. Camera shake (a little) coupled with constant and rapid in and out of focus brought on a headache. Any chance of some camera training or, better still, employing a professional videographer for this sort of close-in work?
Wow.... The v1 design doesn't seem that robust to water ingress. It makes me wonder what kind of durability testing these companies are doing
Our upgrade has been out in the field for 4 years now. We used anyone who had 4 new motors or more in one year and anyone who did professional Enduro or downhill, these are the motors we first upgraded. These were done for free so long as we could monitor the motors. We feel real world testing is a lot better than spraying a motor with water and seeing what happens?
@@Ebikemotorcentre indeed I was commenting on the original design, not yours. But yeah your upgrade looks way more robust
Wow- they didn't have ease of maintaince in mind with these things.
Keep the damn thing away from water to begin ?
But they don't do Shimano motors 😒
My E8000 on my YT Decoy had a bearing fall apart at 4000 miles. I got a new motor and sold it. Now I have a Gen 3 levo and the motor in it failed in 2000 miles. Specialized replaced it with a new motor under warranty. I’m not impressed with these ebike motors so far.
About £220, if you watch the other videos it states that
Did you have warnings on the failures such that you were not stuck out on the trail? in other words, gradual decline rather than catastrophic?
The construction of the motor seems to be totally crap.
Would have been nice if they said how much it cost, rather than a vague comparison to a rear mech.
Cheaper than a £1000 rear mech 😂
@@jonm7272 well that did cross my mind when he said the cost of a rear mech 😂😂👍
@@acelectricalsecurity these pampered professionals have a very different view of the price of things to the rest of us I think, my rear mech cost about 50 quid 😊
@@jonm7272 yeah this channel frustrates the hell out of me, I shouldn't watch it, they would have you believe you have to sell your kidney on eBay to get a decent bike, plus you never get a true review because they are in bed with so many companies and they won't upset them. 👍
Get rid of the motor and you get rid of the problem and expense.
Pretty poor when we have to be reassured that a 4-year old multi thousand pound machine is not obsolete, is considered an 'old faithful' because it has 'lasted so long' and needs a substantial overhaul to keep it reliable. What an appallingly shoddy industry!
Water ingress? NOT FIT FOR PURPOSE!
Any bike manufacturer who claim that the prices can be justified by all the R and D they do on their motors and frames is full of 💩 this is all ancient technology barely fit for purpose!
Can shimano ep801 be worked on? From what Ive looked up they can’t be worked on. @embn
Shimano motors are perfectly repairable, but Shimano are adamant that they are sealed and cannot be repaired. This is not true, but unfortunately Shimano currently refuse to speak to us, or support us! I am sure that if the bike manufacturers knew how many people tell us they would not buy another Shimano powered ebike because of this, I'm sure they would change their mind.
I for one won't buy another bike with Shimano motor, in fact I've ditched my Ebike due to the costs.
So is that a no you currently do not repair Shimano motors.....?
@@johnhilton1360 I'm reading between the lines and if shimano doesn't support them, he can't get replacement parts.
@@vashon100 It's more the software that we have the issue with. Not many eBike manufacturers will supply parts, so we are used to that. But without being able to set wheel circumference or clear fault codes etc. We would rather not do the job if we can't do it properly.
