I expect that due to our muddy conditions we wash our bikes much more than drier climates, and I often see people too willing to use pressure washers on their bikes. I imagine this the biggest cause of broken motors / electronics, but also of bearings on linkages and cranks on regular mtbs. "Sealed" bearings aren't going to cope with water under pressure.

[@TheYorkshireBikeMechanic]

Thanks for watching, your comments are spot on.

[@ziploc2000]

I've seen the same problem on a regular bike on another channel, the owner was pressure washing their bike after each use, and washed all the lubrication our of the crankset, causing extra wear and tear.

[@rivergladesgardenrailroad8834]

[@chryoko]

Sealing a rotating shaft against muddy water is a race against time : A seal will always end up failing vs mud at some point. Even the best seals used on HD and recreational off road machines. What the MtB motor makers need to implement is an easy user changeable seal for each of their shaft interfaces. And clearly ask for a yearly exchange of all the motor seals or every 150h (example) use under real MtB conditions. The same way we change our forks upper seals and oil every year or 100h use.... target is to keep the motor going for at least 20 or 30 000 km before any heavy maintenance inside it and then be able to do that maintenance with spare parts available and clear repair manual free to download to anybody.

[@lozzaridesemtb]

This is a great solution. Units are sealed but dealers can do very little preventative maintenance to ensure customers bikes dont break. I have one that’s done 2500km at the moment and his bearings are shot and luckily its within warranty but this could have been prevented

Recently though I have noticed a steady audible knocking sound which I can also feel on the handlebars when putting a lot of force in the pedals when going up the mountains.

The weather has been shocking, but these motors really do need more than just a sealed bearing on the cranks - at least put a proper seal in rather than relying on the bearing. They should also be made more easily servicable so the bearings can be swapped out without pulling the whole thing apart!

My Haibike Bosch Gen 3 motor was replaced after just over 2 years, but Bosch was kind enough to do it as a warranty fix. The 2021 bike has quite large vents underneath the motor and I can't help thinking this is asking for trouble. I never use a hose as I'm paranoid this will add to the risk.

[@flitsies]

Actually you are absolutly correct, I have an ebike and within the first two years of owning it the motor started to play up, i'm not a person to throw things aways so I pulled it apart checked the motor it was full or rust, and not only that it was full of rust the rust was making it grind and lock. But the up side to this is, if you catch it early enough, you can clean the motor off with a stiff brush get rid of the rust, recoat the windings and make sure the bearings are good re-pack the bearings and the motor will be good to go again so long as nothing has broken, hence why I said if you catch it early enough. So yep the motors are failing because of the water. So to seal the motor to stop the water getting in I simply got some silicon rubber ie mastic and spread it around the tiny tap in the motor. It worked a treat, no more water getting into the motor job done, last time I took the motor apart because the bearings were making some noise the motor was clean no rust, but the bearings needed re-packing due to dust. So perhaps they leave a small gap to allow dust to escape, but I would rather clean it out with a brush every so many thousand miles and my little ebike has done approximately 8 thousand miles judging on the milage I used to do on my motorcycle and I'm doing exactly the same on my little ebike that cost me less than 800 pounds all in with all the changes I did to it.

The only way to keep the moisture out is to provide positive air flow from a 25mm mini computer fan that draws air from inside the frame near the steering head. It should run constantly when bike is turned on and switchable when you are washing it or suspect it needs drying out. A bag of moisture absorbing crystal would also help inside the case. E=Mtb²

[@robhaskins3068]

@@JohnnyMotel99 You are right but some motors Brose for example don't have any seals around the cranks. A problem is that a cooling hollow object will suck in any moisture because a vacuum is created as it cools.

So. I do a lot of riding on my eBike. My frist Specialized Levo motor lasted about 2500 miles and this second one is at about 4800 miles. Maybe 5K at this point. The second one seems to be having a failing bearing on the crank. It squeaks now when I am peddling. Which is just annoying and hasn't caused any peddling issues. The first motor had a terrible failure after I had ridden through a creek. Didn't realize it was deep enough to get to the crank area. But alas it was warrantied anyways. But I put a lot of miles on my motors. And I would say that the Brose does put up with a fair amount of beating. I just wish they did a better job of sealing the crank area. Because I was careful with this motor and I still seem to be having a failure point that will have to be warrantied and replaced a second time. I have a check up scheduled with my LBS. Which is a specialized store now since they bought out the old owners. Makes warranty work super quick.

Given the foreseeable duty of the Brose motor on my Levo, it is idiotic that water can get into electrical connectors and along shafts, into the bearings. I’ve worked in the power industry where we use submersible pumps that run for years with minimal maintenance in sea-water and chemically tainted water. What maintenance is straightforward with care. The methods for keeping water out are well known except in the bike industry where you get charged £750 for a non watertight motor for a mountain bike. I rode motorcycle trials for years, engine regularly submerged crossing rivers without a drop of water getting into the engine, gearbox or electrics. For heaven’s sake, the bloody Brose motor relies on a dob of grease and a 50p o-ring to seal the concentric shafts on the right side. Designed by a chump! All the connectors were going green as the quality is rubbish and no silicon grease had been applied. Modern cars have submersible connectors so what’s the excuse? Again, designed by someone who is clueless about operating conditions!

For 95% off my riding the bike is fine just when I do a jumpy trail but fine on the rough stuff?? They are now on about putting a new battery in the bike? Have you come across this error before ? Thanks Ryan

Hey Buddy !! Have you had any trouble with the yamaha motor?? Am in Perth Oz the bikes never seen rain only time it gets wet is when its being washed. Had it 4 years and done 3000k motors been bomb proof up to now

That's the fault of your LBS not Bosch. I bought my bike from Freeborn, when the Bosch motor failed (flooded) they sent me a box to pack the bike into by next day delivery, collected the following day and the bike was returned to me with a brand new motor within one week. A couple of years later I had another issue (torque sensor fail) 4 days before the end of the warranty, and again Freeborn had it back to me 8 days after I sent the bike back to them. Everything covered, including shipping. We always here how we shouldn't buy bikes mail order and support LBS, but my experience of buying mail order from Freeborn has been wonderful!

Thank you for your comments

[@CaptnSpaulding]

I think a lot os to do with de-restriction too! I did it on my old Yamaha bike where after 500 miles I had to get a new motor. I’m reluctant to do it on my new Bosch Cube especially as it’s a Smart System which is easier at detecting devices or magnet tampering.

[@mrstevepace]

Think about this you can easily pedal past the 15.5 mph limit especially downhill. The motor,internal gears, and bearings will be spinning at this speed doesn't matter if the motor is adding power. Once an electric motor is up and spinning it's current draw drops as the load is lower a standing start uphill in a high power mode will place much more stress on the motor as it will internal gearing. IMO a chipped bike set at a sensible 20mph is not going to suffer any significant adverse wear. In my experience of 3 years and 16000 miles of commuting on an ebike the weather was my worst enemy and required constant carefully cleaning of my bikes a bit of well placed grease around the outer crank bearings helps but it has to be regularly cleaned off and replaced. Had one Bosch motor replaced fussy free on warranty after going submarine through a puddle and so far had no problems after 2 years with my Yamaha PWX equipped Giant.

[@CaptnSpaulding]

@@mrstevepace I think this is why the Volspeed chip works better than most others as it can limit to any speed where as say Speedbox is unlimited and those cause motors such as Bosch into limp mode. 5 times and you have to go to a Bosch dealer and they’ll refuse to fix it free. I was lucky with my Yamaha which I did the magnet trick for which also gives unlimited assist there was no obvious or traceability so they swapped the motor for me. So many posts on FB groups of motors stop working after using chips or magnet hacks

[@mrstevepace]

@@CaptnSpaulding I agree re Bosch they can detect chipping and lock you out if you set speed to high. I did have a Volspeed fitted to my bike removed it B4 taking to workshop and no adverse data detected by the Bosch service software. I did sweat for a bit mind until the tech confirmed I'd be getting a new motor under warranty

from Australia. winter riding is best, summer riding is like riding through talcum powder! it gums up everything! chains gears bearings, horrible stuff. im running a cyc gen 3 stealth at 2000w max its amazing and modular. so if something brakes i can just replace the part. as in controller gearbox motor wiring loom and driving mech. each part is reasonable with price. my only bitch is postage costs and time.

That's bad design, isn't it. The TQ motor is IP67 and Specialized non SL (1.2, 1.2 E, 1.3, 2.1) are IP67. I'm riding the Rail 7 and no issues, but I would not buy again an eMTB less than the IP67 rating in the motor. I need to wash my bike a lot by using a power washer, but I need to be very careful in the cranks area. BTW I wash my bikes using the Bosch Fontus battery powered washer. There is a "shower" mode, which I use mostly. Power washer mode I use for the tires if needed. In Finland, the winter weather is killer. The snow piles up in the cranks area, and we all know the story end :-)

Being a mountain biker since I was a nipper, and a keen motorcyclist I simply can't see the appeal of investing lots of money into something that won't last long term, That said I love the concept of e bikes, and probably will buy one at the right price eventually

[@TheYorkshireBikeMechanic]

Hi, Thanks for watching and your comment

[@karlmoreton8182]

An international standard for mounting motors to frames shouldn’t brand/model specific. Once the motor is discontinued it shouldn’t then become landfill. Circuit boards shouldn’t require de-soldering to replace bearings and all internal gearing should be wear and tear items that are replaceable. As a complete bike they certainly know how to charge ! Finally battery packs, why aren’t they repairable, say return to Shimano for refurbishment, mine had an internal fault after very few charges and I had to replace with new, unable to find anywhere to repair or recycle the faulty item due to the nature of the BMS. I sold the bike in the end and gave the new owner the old battery as well otherwise I’m not sure what I’d have done with it.

My Nikolai eBoxx 2020 Bosch Gen 4 motor has almost 10 000 km and i can hear a noisy "click" metallic sound when i push to the left pedal reaching the 6h position. Nothing with the right pedal pressure. If i stop pedaling (pushing on the left pedal) then i hear a second click right after the first one as if there is some kind of inertia to the click cause.... I explored all other potential root causes and failed to find any one. The frame bearings are super strong (vs other mass produced brands i know) and feel OK on the fingers and not cracking when jumping on the bike under whatever position. Pedals are 100% OK also. I tightened the motor fixation bolts (except the brackets hollowed Torx 25 that i wait for the special tool for it). The noise comes clearly from the motor area. Shall i ask for a motor replacement out of the 2 Years warranty ? (cost about 800€ ...). Or shall i continue to use the bike until the motor fails completely ?

Bike manufactures would be better off upgrading bearings etc rather that just replacing a motor surely? Oh and spesh offer rider assist on non warrenty parts 👌

[@MyKharli]

I use the cheapest 48v hub motors , no problems with 5 conversions and combined well over 20000m all weather riding with hills .Diy is the way to go . Everyone i know on `an ebike `has had expensive problems and they end up being unused . There is no justification for the non standardization and prices of ebikes imo . Its just pandering to those with to much money like everything .

[@chryoko]

There is another point that makes me crazy about full suspension MtB frames is that they use (99% of them) ball bearings on the suspension joints : but a roller bearing is made for rotating full, not for such low amplitude high load stress ! The best technical solution used in the industry in that case is to use bushings on the joints : Self lubricating bushings types (steel-bronze-polymer composite material) with if possible a greasing plug to insure longevity and low friction over time. Greasing should be done periodically (eg. every xx hours of ride) . So yes, it will weight a few grams more and will need a minimal maintenance than a "cartridge roller bearing" solution, but such bushing will last forever if well maintained.... but who cares on an eMtB ?

[@TheYorkshireBikeMechanic]

Hi, Thanks for watching and your comment. a great comment and one that I always think about when doing a bearing change.

[@chryoko]

@@TheYorkshireBikeMechanic i had a Specialized Stumpjumper FSR that was killing suspension bearings : I started to change them after 2 years , then once a year, then once every 6 months, then every 2-3 months , then i got tired of it and i scrapped the frame altogether. Those bearings are tiny, fragile and poorly fitted into a poorly machined frame that do not follow the recommended bearing manufacturer tolerances (OD, ID, co-axiality, squareness etc ...) and that impacts the durability of those fragile bearings a lot. Even more than water ingress ! At then end after replacing those bearings a dozen times, you do what is called an "ovalization" of the housing that induces a play/micro-gap that kills even quicker the new bearings. Only solution would be to machine new housings (larger Diam), shafts (larger Diam) and put a good quality bushing into it (Glycodur style). I know guys that did it successfully. But you need a lathe and a milling machine for that operation .....

@@TheYorkshireBikeMechanic I understand you being a honest person trying to help everyone but I was surprised when I found out that Bosch doesn't honor their warranty when bike is not owned by the original buyer! How is that legal at all? I bought two Bosch bikes from the original buyer, both with very low millage. I have all of the documents and when I asked the original seller for software update I found out it is not free service as I'm not the one who bought bikes from them. Despite both bikes being less than a year old! Why bother paying premium for Bosch if they treat their customers like that?

no first hand experience, but it strikes me odd that people seem to think 10 k miles is a huge amount for an ebike motor. is that really the case? 10 k in a regular bicycle is only getting started! that's two years worth of riding for someone who rides 10 hours a week.
