My Brose packed up 1 month out of warrant and no claim due to expired warranty. I still have it after spending $100 on a new one. Does Pete have operations in South Africa?
I had to repair it by myself. I live in Ecuador. I found that the bearings from one side were awful condition but also there were humidity in the interior of the motor so I had to clean it all, change bearings and still working fine. It's a Bosch performance CX 2nd gen
Pleasantly surprised how complete overhaul of the motor is only around 350 pounds,over 5000 miles on my e8000 , still smooth but i wont hesitate to send it to these guys when needed Very reassuring vid 👍🏻
Do a video about ebike battery repair. Completely different story. Just had to pay specialised £1k for a new gen1 levo battery because of a single cell out of 40 cells dropping below a voltage threshold. Their proprietary BMS turns your bike into a paperweight with no way to repair the battery. Not very sustainable.
None of this ebiking is sustainable, its the worst thing the companies have done. making motor mounts unsable year on year. cant get a newer motor or a newer battery. Just sling the bike and buy new is the moto.
@@BazippysVideosyou noticed this video is about repairing e bike motors? new motors are available also, or reconditioned.....which seems as sustainable as any other sport with a motor.
Great video! These guys have a lot of knowledge-i would love for them to do a e bike motor top tips like: How to clean, how to maintain, what faults to look for. Also, they might share which motors are most reliable in their experience?
Great information about repairing e-motors and very good information about the damage a pressure washer can do to the motor. Sad to hear e-motor manufacturers are slow to seal motors appropriately from the dirt and grime of a true mountain biking experience.
They have a great set up @ bike motor repairs & a wealth of knowledge, if they realise that water ingress is the main cause of motor failures both mechanical & electronic why haven’t the big motor brands ??? If Tesla can make a waterproof motor for very fast car so can Bosch or Brose who are both leading electronic manufactures in the automotive world. Its about time they all sorted them acts out & supply products that are fit for purpose. some bikes are almost as expensive as a budget car & this kind of reliability would not be accepted in the automotive industry. Rant over. A great look @ a small indipendate company providing a quality service in yhe uk.
What centers like this do is fantastic, but firstly, these repair centers are few and far between, and secondly, as mentioned in the video, there is not enough support from the original manufacturer. Keep in mind that these motor repair companies are getting the majority of their replacement parts from other motors that have failed in different areas. Imagine buying a car where the manufacturer doesn't supply parts for local mechanics, which would force consumers to buy a replacement car - this is an absurd situation. Also mentioned in the video, 90% of motor failures are due to water ingress. How is it that a rear mech can be made to be water-proof but not the motor? As proven by the motor center's efforts to seal the Brose motor, they have drastically increased its life. It's absolutely doable, but for some very odd reason, the manufacturers are choosing not to. Granted, all machines fail at some point or another, but there are clearly some very simple, tried-and-tested engineering solutions that are not being used in these premium machines. At the price of an e-bike, it's just not acceptable.
What's going to be telling is in 2+ years, when everyone's bargain ebike fails out of warranty, what will the consumer sentiment be towards these manufacturers when they realise they can only buy refurbished parts recovered from other failed motors, which will become fewer and fewer as time goes on. Its the same failure to future forecast as we saw with bike companies failing to realise that 2021 bikes sales would eventually end. Its just going to compound the issue of sales-slow down and will negatively impact the bike industry for a good few years. The shortsightedness of the industry know's no bounds.
Hi Dafy, distance shouldn't be such a problem, as most drive units can be shipped to motor repair shops in their country - eBike Motor Center has very strong network of partners worldwide. Regarding replacement parts, all service parts such as bearings, seals, bushings, belts, etc., are brand new and typically of equal or better quality than the original components. The "very odd reason" is simply friction, which leads to high energy consumption. Everyone wants to buy the eBike with the best battery range... Best regards, EBMR e-Bike Motorreparatur (Austria)
@bikemotorreparatur “Everyone wants to buy the eBike with the best battery range...” - but whats the point in range if your motor dies within a few hundred miles? Not meaning to go on the attack out the gate, and I understand this isn’t something within your control, but this logic is questionable at best. I think anyone whose experienced issues with their ebike would rather a bike that’s reliable over having extended range, especially riders from wetter climates. Parts - Bearings & seals is one thing, but bespoke motor components is another. Are you able to source brand new motor controllers, the battery management system, a brand new stator / rotor, does the manufacturer provide this to you directly or are they third party solutions? How transparent are manufacturer's with you regarding these parts? Genuinely curious because I hear otherwise. There is currently no legal support that forces the manufacturer to supply replacement parts for aging motors, as is the case in the auto industry (within the EU atleast). Its simply down to each manufacturer on how long they choose to support their products, and as we’ve seen with the questionable warranty process of some, this doesn’t induce confidence for the consumer looking for a bike that lasts and can be continually repaired. Also lets not forget, the terminology of 'lifetime' that manufacturers use regarding their motors is often the warranty period only. So when manufacturers like Fazua claim that their bearings last a lifetime, what they really mean is 2 years. I truly appreciate the service you provide customers to keep their bikes going, but the manufacturers need to do more to support you and their consumers. For a premium product, we should all be expecting better.
9:00 I would love a separate video where Pete shows the extent/details of the "few seals and a bit of magic" involved to show what manufacturers SHOULD be doing. And address if there is anything us users can externally apply to the motors to protect our motors without violating warranties.
Interesting but there is lots more available too for issues other than bearings e.g. belts, spray clutch issues, plus upgrade kits on lots of the things that break too.
I've had to replace motors and a motor controller inside the tongsheng tsdz2 and it wasn't difficult or expensive. Just annoying that the open source firmware defaults were set to fry these components and not massive/obvious warnings about changing the defaults.
I hose mine all the time and my current motor has been in for a year so far. But then I got the specialized 4 year warranty so I’m not worried about it yet
Over 20.000 km on my Bafang BBSHD motor, jetwashed my bike many times no bearing, gears or cables replaced, just the gasket seals replaced every 2 years and replaced the grease and i know many other people with the same motor who had no issues, looking at these 250w ebike motors and it's hard to belive how much money people spend on these things and they break so eazy.
Done 17K km on my eBike and never once cleaned it with a pressure cleaner. Quick brush with T wash and a rain off sprinkle from a distance then straight into shed with full tank of air blow it off and out asap. Try to avoid riding it in the rain and never ride it through water.
I live in Ireland. It rains quite a lot here. I'm waiting on my first e-bike for daily commuting and a general workhorse. A Cube Kathmandu 750w 85nm. €3,500. The whole point of getting an e-bike is to make commuting and travelling especially in wet and sometimes VERY WET with lots of ground water and windy weather easy. If I can't ride it on a wet day for a 40km round trip without worrying about screwing up the motor then I may as well just cancel my order right now and put that money into something else instead. I think I might need to have a chat with the bike shop.
A motor from one of the better brands probably costs around 900-1000£ to replace? Maintenance for 300£ sound horroble! I'm excluding rest of the bike here for the comparison, but imagine paying 10000 or 20000£ for a car and repairing it for 3000-6000£ in few years. I don't think that brand of car would get a lot of sales. Unless it was Italian, perhaps... Then it would be normal.
They didn’t say don’t get it wet, they said don’t use pressure washers or high pressure hoses. Use a low pressure (adjustable) end on your hose (or a plug on brush) and ALWAYS clean 90 degrees to the bearing surfaces otherwise you’re just pushing the dirt and water inside. I’ve done this for years and bearings are all good.
Best way is to spray a dirt cleaner like Muck Off, Truck wash, Motorcycle cleaner etc. and brush with a soft brush then hose off with a sprinkler on the hose. Other things to watch are long deep flooded ruts, deep water fording, car racks on wet roads etc.
Good idea the mechanic had new ebike take the motor out and just seal it up best you can! Even a new seal on outter side halfs, anything to beef up the seal's but then they need a hole to drain so whare do you start?
Steve: So Pete, a customer comes to you with a motor like this, totally broken, what do you say, what do you suggest to them? Pete: Oh that's easy Steve, "Have you considered golf?"
Just not good enough! Manufacturers should not be selling motors that allow water ingress. I rode my Rocky Mountain altitude powerplay in River crossings well above the motor and battery for hundreds of metres in a recent Alpine ride in Australia. I decided to drop the motor out of the bike and inspect the battery connections and opened the motor to inspect whether there had been any water penetration and there hadn’t. I also regularly power wash my bike and apart from the occasional corrosion on a headset bearing I haven’t seen any issues at all.
We have done many Rocky Mountain bearing replacements, trust me, they are no more invincible than any other motor and deep water fording / pressure washing will definitely kill it eventually.
They are indeed, pop into your local Giant dealer if the bike is still under warranty. If it's not message a third party motor repair specialist and they'll be able to help!
Unless an aspect of your life like an illness or injury requires you ride an ebike, I can't imagine the sheer amount of money people spend on ebikes and then constantly having to pay this amount of money just to keep them going, all for the sake of getting up a hill a bit faster. Think I'll stick to my real MTBs, gravel and road bikes. Bonkers.
Ahh come on you did not ask the question.....which is the most reliable!!! I interesting to note that 90% of damage is water. I keep my bike in a drying room. It's 30% humidity and 25 degrees for an hour in there after a ride!!
Why SHIMANO dont repair motors? And dont shels replace parts? And dont give options to recycle? I will not buy SHIMANO again ever ,please litle respect to the planet health mr shimano
6:09 - Is he seriously saying that you shouldn't use even a GARDEN HOSE on your bike? What kind of crappy ass build quality is being sold to us as premium products?
I have a 2019 Turbo Levo, One of those that Specialized gave the 4 year extended warranties to due to lots of problems with the new Brose motor and belt failures. This suited me very well especially as I bought the bike second hand with a mere 21 miles on - Yes 21! - and the warranty was for the bike, not the owner. Quite a few of my mates have the same MY bike and all have had at least 1 replacement motor. Mine remained sound throughout. After the warranty expired I chanced upon The eBike Motor Centre's Brose upgrade video. I watched it with interest and decided to contact them for further details. I was impressed with the response so I took my motor down there to get the belt and sprag bearing upgrade carried out.. The motor was turned around quicker than they said and they also found a couple of bearing that were past best. They offered to supply and replace them for what seemed to be less than I'd be able to buy them retail. I went and got the motor and the top man from the vid chatted to me. I thoroughly recommend this company as the whole outfit appears extremely customer focused, professional and realistically priced.
It's great to see small businesses popping up and thriving. However, this doesn't "fix" the problem. Nor "cement" consumer trusts to buy another EMTB after or sometimes even before motor failure. Example. One could own a CRF450R. From 2005. Nearly 20 years old and go to dozens of websites and order: Every. Single. Bolt. Seal. Gear. Bearing. ECU. From OEM for that motor. Considering the cost and complexity of EMTB vs. Moto Bike. This lack of availability from EMTB manufacturers is inexcusable. Now, the loss of logic. If a diagram and catalog website were created by the manufacturer offering such a thing, plus possible superceded parts for "vintage" generations for the consumers. Would this not generate profit? More importantly, would this not "cement" trust to buy new and boost resale value? To gain MORE consumers? One more thing to consider. Water intrusion. This could be solved with a simple threaded nipple. With a hose and one-way check valve. Water drains and evaporates. Coating the case internally to prevent corrosion. Add potting to the circuit board. Failures eliminated. Unless........
It was seeing a video about Pete’s e-bike motor centre and the costs to repair that encouraged me to buy an eMTB. The thought of replacing motors with completely new units had put me off !
didnt wash my 19 levo since 2019 motor works smooth as it did on day one, it is just like with classic cars you dont wash it you wipe it instead thank me later :)
I bought a Husqvarna e bike because of this channel and it broke in 2 months. My Santa Cruz Heckler died after 1 month and shimano took 9 months so replace the part and the battery then died too. Ive wasted $30,000 on e bikes.
Now here comes the real interesting question: How about Shimano E8000 motor overhaul if it's wrecked. There's not a single shop in germany that repairs an E8000. They all switch to a new one -> ~900€. 🥴 There are also people talking about the E8000 can be replaced 1:1 by the EP8. Is that true? Thanks for any advice and greetings from Cologne, Germany 🍻
Shimano are one of the only companies out there that will not support or talk to anyone that works on their motors. Therefore, people refuse to support them until they support us. Campaign to Shimano and if they support us we would be happy to help.
The E8000 is not included on the motors he can repair- Shimano's fault, the PCB is the issue IIRC and access to some bearings?? have a friend who went through 3 motors, all disposable effectively....Would never buy one with Shimano- stick with Bosch or Yamaha(pretty experienced with 2 wheeler motors and my motorbikes in the 80's were ultra reliable)
Really good service ,I have a winter training bike used in all weathers floods mud the lot so gets proper abuse, £350 full overhaul every couple of years isxa bargin.
Definitely don’t jet wash your bike. My 2018 Canyon ESpectral on 8 is on original shimano motor and rides sweet af. Out today just a quick light hosing off plus a stiff brush and it’s ready to rock again 👌🏽
The timing on this is interesting. I just had bit of a scare where I thought I had done a motor bearing (turned out it was crank bearing / fitment thankfully) but it was interesting to research. I contacted the Australian branch of this service and was told as far as servicing is concerned, they wouldn't touch my Shimano EP8. They would be happy to sell me bearings, but as far as servicing was concerned, I was on my own. Reason being their experience in cracking open an EP8 was too risky, as it was a total crapshoot as to whether the motor would ever work again or throw up errors and were just too inconsistent and temperamental to work on. To me, that's unacceptable on Shimano's behalf. Bearings are a wear item and should be 100% replaceable, that Shimano either straight up does a warranty for them, or in the event it's out of warranty, expects you to just buy an entirely new unit puts Shimano on an insta no buy from me going forward. Ebike motor manufacturers are surely taking the piss here. It's an AC motor with speed controller and torque sensor, it's not new or complex tech; to me, it seems like these companies are being purposefully arbitrary in their design process, it seems primarly, on the software side of things to lock out consumers from repairs. There's no reason any component in these motors should not be available as spares that can be replaced or serviced. Also on the pressure washer (not even hose), seriously? A pressure washer on a wide fan setting should NOT be causing any issues. If the bearings on these can't handle even a garden hose, these companies should be taken to town on the suitability of their designs. I can understand a pressure hose on full blast staight at / into a motor, but a hose or wide fan setting on a pressure hose to mist shouldn't be a concern for a bike which is expected to be used in a variety of weather conditions.
Im in Australia also and agree with your points, being a Bosch and Fazua owner, I'd hope these thing last the warranty period more so the Bosch unit currently at 7000ks, the best thing you can do is apply a bead of waterproof grease around the crank splines to avoid water ingres.
By all means use a pressure washer on your bike and motor, the expert said specifically do not use a pressure washer. Go for it. Pressure washers destroy motorcycle parts just as well. And normal bicycles.
Shimano motors are not currently supported by us (eBike Motor Centre) nor are they supported by most of our partners, because they will not even entertain talking to us, let alone helping with any software etc. They are a particularly troublesome motor to repair for the long term. If Shimano owners campaign to Shimano to support us, or even just speak to us, then perhaps we could support you guys fully outside of warranty.
Battery’s are the biggest rip off. Do a video if you dare on bikes that are useless because batteries are unavailable. I have Focus Sam’2 with zero support because no batteries are available.
@anonymousone6075 Please can you explain the process for 'redoing the crank grease' on say, a Brose motor? Interested to understand how you perform this and which grease you would use. Perhaps link to a video of you doing this '5 minute job'?
What gets me is that these motors are so poorly protected from the elements, I have had 6 motors replaced on specialized level and my new kenevo, its not will the motor fail but when.
We're always looking for customers who have had multiple motor failures, because we love a challenge and can definitely stop you having to walk home so often!
@Ebikemotorcentre thanks for the reply, on the last motor replacement on the 2022 kenevo the shop added a seal kit that is meant to help water ingress, living and riding in Scotland I don't know why specialized don't fit this kit to all northen country bikes. I do still have motor waranty but can't see me buying another specialized Emtb as its just heartbreaking how much these cost and how hard it is to get things fixed under warranty.
4:28 which is justifiably the 'most replayed' part of video and as Steve said is great advice on a way of easily keeping tabs on your ebike motor health before its too late (ie: very expensive vs mildly expensive) - Great info!!! The only other best advice imo is dont power wasg around bearings or motor!!!
Used these guys for a while now for my customer's bikes... Their service is absolutely top notch and worth every penny. Listen and take heed, stop washing your bike so much and just ride it.
I'm in On, Canada and use mine year round. I have to wash mine after spraying salty snow a slush all over the motor. I didn't wash it for 1 winter and when I hosed the motor down, the casing was corroded and quite pitted.
Good video! 👍 Nice to see the industry slowly getting organized. Common faults will become more frequent as the e-mtb pool gets bigger. Looking forward to electronics “out of warranty” support as well.
I can't even find a place close enough to walk my bike to for a flat repair. Local bike shops won't touch an ebike unless they sell it, not even a flat! So now I need to spend another almost $1,000 for a trailer hitch instal and bike rack that can hold my 72 lbs bike. Turning into a money pit.
So, what about rebuilding Shimano EP8 motors? There are a lot of Shimano motors in bikes. Nothing was said about this in the video. Why would they be any different to rebuild?
In my previous post I spoke about it (you picked out the water pressure part). They won't do Shimano because they can't reliably service them without getting errors post service. So they just won't touch them which is fair enough on their behalf, Shimano on the other hand need a pls explain on that one
Most of the Shimano drive units will sooner or later encounter the E010 error, which typically indicates a problem with the torque sensor, often stemming from communication or calibration issues with the main PCB. A problem that is not repairable. As a service provider and mechanic, you don't want to be the last one to have worked on the motor, even if it was months ago, and you've only repaired mechanical parts. Under the one-year warranty, you may be obligated to purchase the customer a new drive unit, which can cost around €1000. This could prove to be very costly in the long term. Best regards, EBMR e-Bike Motorreparatur (Austria)
@@ghostdog6471 I’ve been riding a bosch motor commuter for about 3 years now, and mine is still going strong after over 4k miles. I do regular maintenance and do my best to never leave it out in the weather here on the coast. I’m hoping for many more miles. I have 2 trailers I can use, plus I stay set up with front and back racks for full pannier set up. I can go with up to 6 panniers with my burley coho in tow.
to be honest that's very affordable to have it fixed/serviced. I would definitely like to see better waterproofing on emtb's tho. They could DEFINITELY do better.
@anonymousone6075 it isn't claiming anything...the cost will be purely dependent on what is wrong with it. If it needs a full overhaul, then surely at half the price of a new motor, that's better than forking out £600/700? 🤔
unfortunately it looks like i'll be going down this road as haibike/evans wont accept there's something wrong with the motor unless numbers come up on the handlebar screen, ?? cf12 and px2 motor
i honestly dont understand why there no fully sealed, motorbikes engines dont have any of these problems we are in 2024 and still have problems like that
Perhaps next time EMBN reviews the latest tech bike with auto changing gearboxes and the like, they should consider how repairable it will be down the line - difficult I know to fit into the short video format but it is a big issue for those of us who can't afford to just go out and buy a new bike when the warranty on the current one runs out.😀
Would it be possible to do a chart or a list of recommended service interval for different motors based on Petes experience? Sure a pressure washer will destroy a motor quickly, but there must be a certain amount of km's where at the latest its good to do a preemptive maintenance?
After 3 years and a few thousand miles my Brose motor from my 2021 levo has given up. The specialized app says it’s a belt failure. Was thinking of sending it to the motor repair centre but a very well respected and trusted specialized dealer told me not to and that I’d be better off just getting a new motor as specialized apparently offer an assisted purchase scheme on replacement motors. Assured me I wouldn’t pay full price for a brand new motor and I also get another 2 years warranty. Probably still gonna cost around £600. The reason they told me to do that was that they think the electrics will probably soon fail too and Brose don’t sell replacement circuit boards so I could spend a few hundred getting it repaired and then be screwed a few months later if the electrics go. Not sure what way to go now. Any advice would be appreciated thanks.
My original Brose motor (2021) conked out just within the 2 years warranty. Replacement motor fitted at no cost. 6 months later and the replacement motor fails - but this motor had no warranty - what's that all about? So I went for the assisted purchase - £600 or thereabouts - this with a 2 years warranty. The whole situation seems crazy! You wouldn't buy a car and expect to fork out for a new engine within 2 years - yet I'm on the 3rd motor inside 3 years. I can see me reverting to non-assist at this rate. Trouble is I love the Levo.
Send it to them anyway...for a small charge they can open it up and check out what the damage is, but they won't do any repair work until you've accepted the estimate costs. It's possible that you could be back on the bike for a small cost if not much wrong. If it needs a whole load of parts then you can still get your new motor if you wish.
It's a shame there is a lot of misinformation out there. And its probably not your trusted dealers fault, he would have heard this from someone else etc. I can assure you, one of the strongest motors on the market regards electronics is Brose! They are one of the only motors that site the PCB outside of the motor, in it's own compartment, this helps protect it from water ingress etc. But the actual electronics are near bullet proof. If you have one of these motors upgraded by us, it makes the whole motor much stronger and very water resistant. Sadly, you don't get that with a new motor, you just go back to where you started.
Ahhhhhhhhh. I better stop using pressure washer. I just ordered some brushes and a hose from amazon. Thanks to you. You may of saved my bike from future damage. 😮
Great video, very interesting and less than an hour away from me. I may get my 3.5 year old brose motor booked in for a check even though it's been reliable so far.
Great interview EMBN! I've had my E8000 apart twice to change bearings. The second time was shortly after the first due to water ingress from, wait for it, pressure washing. I was at a super muddy race at Muju in South Korea where they always have high power hoses available. The second service was easier as I only dried the inside but it makes me wonder if it was the mud or the washing that did it. The silicone I used might not have been correct. Does anyone know what Shimano seals their motors with? They seem pretty tight lipped about how to go about working on their components. Do they offer small part replacement? Steve's advice about hearing or feeling anything is spot on. As soon as my cranks had a little noise, I changed the bearings. I've had to fiddle with the power supply cord a bit too as well as bend the tabs inside the external battery connections towards the pins that insert into battery so they will make contact. That external battery gets jostled around so much the male pins have deep grooves in them and the little tabs weren't reaching. That and scuffing the plug that goes into the motor because the round pins corroded and I kept getting an E010 code that drove me crazy for a month before I solved it. Anyway, I've now put 5 years and nearly 20k of hard MTB on the E8000. Still going to strong as long as I can keep the power getting to it.
I paid about $1000 for a Brose "rebuild + upgrade" by eBike Motor Repair in Tennessee (USA). This cost also included a new (used) crankshaft because mine had corrosion damage. The rebuilt motor is quieter than when it was new, and I'm hoping the added seals and beefier parts will keep the motor alive longer than the rest of the bike (2019 Levo). And I will be VERY careful to keep water streams away from the spindles when washing the bike!
@@rirrid5662 I am choosing to believe my motor received this set of stuff in addition to the replacement crankshaft and rebuild parts/labor. "We now offer an upgrade for all Brose motors. This includes the following: Uprated thicker, stronger, Brose carbon fibre drive belt. Uprated heavy duty sprag clutch bearing for the motor drive pulley Uprated heavy duty sprag clutch bearing for the crankshaft drive Single lip rotary shaft seal to stop water ingress into the crankshaft needle roller bearing and beyond (This also stops rust damage to the crankshaft bearing surface and premature failure of the crankshaft needle roller bearing) Genuine Brose bearing cover seal for the right hand crankshaft ball bearing (Not factory fitted until 2017) Waterproof long life grease packed between outer bearings and motor covers. (This helps stop water sitting in these areas and seeping into the outer bearings). We also fit an external X-ring seal each side of the crankshaft to further stop the chance of any water ingress into the motor. We remove the two ECU cover screws and seal these to stop water ingress into the ECU. Finally, we treat and coat the motors’ electric plugs to stop corrosion and water entering the ECU by capillary action along the wires."
@@2011buddyleeI decided against a new Brose motor because it would have the same weaknesses as the one that failed.

bought a 2017 Focus w t E8000 motor/ died just out of warranty (of course!) but after a lengthy wait when t motor was sent to ShimanoNZ they replaced it for nix…. Very impressed/ rocking-on w t new one.
At about 5000 miles on my turbo levo I sent in my motor for a top notch rebuild with upgraded bearings and seals and belt. ($900) Then new tires and new valve stem and new cassette, new chain, new front chain ring, and new bearings in my rear hub. $1500 total. Good to go again! Ebikes require maintenance!
Most evoke batteries cannot be recelled (keep the case and replace the batteries) as doing this damages the Battery Management System. This is why people do self conversions as the batteries can be recelled.
Great informative vid Steve, great pricing on repairs, hopefully not needed but i do ride in the Lincolnshire slop with Brose, great for tate's, not so great for bikes of any kind.
Great video thanks. How do I grease / Oil my crank bearings. Can I use chain oil or is there a special grease I need to use. From your video it implies most failures occurring to motors due to water ingress on the crank seals so it would be useful if not critical to be educated on how and when to maintain this on an ebikes. Thanks, Oli.
Don't oil them! Have a read through the e bike motor centre's website... im pretty sure that's what they stated on there. There is a lot of good advice... such as I learned that yamaha motors should be regreased internally after the first couple of thousand miles due to the grease used drying up.
@@andyarchitectthanks for info. I read their website and like you say lots of good info. I also have a Yamaha motor. It's a crazy situation where all the MTBs are fitted with essentially road bike motors with no additional upgrades to handle wet and muddy conditions. I'm pleased EMBN are starting to do features in this subject. I would like to know the correct grease to purchase.
@@oradcliffe I considered regreasing the gears myself... however I am already planning to send it in to them as I'd rather have it done by people experienced in what things should look like and how brings should feel etc to make sure I don't miss something important. I think it was some kind d of waterproof or marine grease they said they upgraded the yamaha grease with, but don't think they specified an exact brand or type.
@@andyarchitect We use the genuine Yamaha grease within the motor, but we do add a very tacky waterproof grease behind the motor covers before the bearings are seated. This stops water sitting between the motor covers and the bearing seals. We also add this to the crankshaft rotary lip seal and add a garter spring to the seal for a tighter seal.
Cruel capitalism never wants anything that does not break down. These engine designs are deliberately made so vulnerable to water. In other words, replacement or expensive repairs are the things that manufacturers like the most. Stay away from these types of bikes with complicated and unnecessarily complex engines. Choose Hub motor bikes, which are the simplest and must-have designs. This is why all expensive bike manufacturers have hated Hub motors since day one. Because they are simple, long-lasting and easy to repair.
