Conformal coating is applied on this kind of PCB, you can even put them underwater

[@silasmaxwell6745]

Worst engineering I've seen in a long time. By no means does a geartrain belong in the same sealed area as a circuit board. Board should be sealed off, gearcase should be separate full of gear oil or grease.

[@stevepodjaski1139]

That's what 10k gets you lol. Junk

[@oni19919]

Agree

[@Metal-Possum]

They all do it. Bosch, Shimano, Yamaha, Brose, Bafang, etc. I'm pretty sure all of those companies know what they're doing give how many millions of the things they've sold, and the already massive success that Shimano, Yamaha, and Bosch have had previously manufacturing other things.

Awesome to see this break down. First time seeing a mid-drive taken apart

[@granitecolorado]

I have a Bosch motor and it was damaged from water ingress. Everyone said that I would have to send it to Germany to get fixed. I carefully took it apart and changed every bering and reassembled it. It works perfectly

[@dheetbanda007]

Now that's what we call an independent person.

[@goku445]

you got the parts easily?

[@granitecolorado]

@@goku445 Yes, I found a company in England that sold the complete repair kit for $147.00 and they have a warehouse in USA. To send the motor to Germany was like $1500.00. I just took lots of pictures with my smartphone and very carefully disassembled it. Now they have a kit called mud stopper and I put that on and it stops the part that lets water in

[@granitecolorado]

@@goku445 The place is called ebike motor repair. And I think it's in Tennessee. I found them through a company in England called ebike motor UK

It’s called new bike

[@HardDiskLover]

It's almost like small gears with modestly high rpm's and toque need proper lubrication and not just some grease. If they put this into its own small form factor gearbox with proper gear oil it would last much longer

[@TheMetoMarfoza]

То, что мертво, умереть не может. Я про гениальную идею засунуть электронику к зубчатой передаче.

[@TheEscape2012]

One might think Shimano is able to produce a gear that is strong enough for this little Motor. I mean there are motorcycles with 100 horsepower and more and they hold up

[@rustynuts4426]

Bearing play transfered to gears allowing excess movement between the meshing and that allowed damage and accelerated wear to happen

[@S54B32_]

Imagine driving this bike, then hearing this cracking sound

It’s not fixed and knowing Shimano you cannot buy the part, or at least not for less than 80% of a new motor.

Thank goodness for people like you i wouldn't know where to start, amazing at seeing something broke and telling myself oh i can fix that then i take it all apart not remembering how to put ot back together and i end up disposing of it.

What do service manuals say about gear box maintenance on this type of motors ? Following the rules shoud be the key to avoid premature gear damage like this one.

[@dimarevidovich7616]

Качество одним словом, аж покупать передумал

[@paulooliveira8284]

E tenho certeza de que isso não é barato.....

[@shayan4040]

So is the fix just replacing that damaged part at the end? And was water getting in the original culprit for the defect?

[@aldoperez4115]

Cuando un producto es complicado para hacer mantenimiento está mal diseñado, a esto agregarle: 1- La electrónica junto a la caja de engranaje, está mal. 2- La caja de engranaje no tiene grasa, es un problema muy común, debería tener aceite pero no se comprometen con la estanqueidad, la grasa se corre a los laterales y los engranajes trabajan como sino tuvieran lubricacion. 3- Los engranajes no son de materiales adecuados, muy blandos, no usan acero y engranajes de bronce como corresponde.

Tiny motors outputing a lot of amps ..what can go wrong?

[@ferrumignis]

Apparently not much happens to the motors. The gearbox OTOH, that's toast.

[@evronetwork]

@@ferrumignis it's easier to bust a motor of this size compared to a 1000w gearless hub motor

[@ferrumignis]

@@evronetwork Hub motors add a considerable amount of rotational mass and unsprung mass, far from ideal in something as light as a bicycle. A mid drive also benefits from the torque multiplication of the chain & sprocket variable gear ratios, whereas a hub motor is fixed. OTOH a hub motor is simpler and lower cost.

[@evronetwork]

@@ferrumignis A hub motor doesn't put strain in the chain or the gears ...also if you need real power well a hub motor is the obvious solution(you can also use a throttle so no peddling at all)

[@ferrumignis]

@@evronetwork Once you can make a hub motor light enough that it doesn't hugely add to unsprung weight and moment of inertia I'll agree. Right now its like attaching a boat anchor to your wheel.

[@47f0]

​@@simonpeneau7802- And yet, studies show that ebike riders in the real world show at least as much health benefit as conventional cyclists. The study authors observed several reasons for this. E-bike riders rode their bikes more frequently - they were more likely to use their e-bikes for errands that took a bit too long, or were a bit too far for conventional cyclists, who would default to other transportation instead of riding. They also tended to ride further. Maybe the genius move in your case would have been to actually look these things up.

@@simonpeneau7802 - Oh goody - more testosterone than brains, and (of course) a KZbin champion rider. I thought that was an American disease. Apparently not. The conversation was about the lack of knowledge of those who claim you can't get a workout on an e-bike. The facts, which I cited and can provide more evidence of, don't support that notion. But you're obviously an intelligent guy who likes to keep his mind free of all those annoying facts. So here's the deal - I'd love to race you, because there are only two possible outcomes: 1) Your friends will laugh at you when I beat you, or 2) they will laugh at you a very different way when the see you challenging a seventy-year-old man. I'm fine with either outcome. BTW - saw pics of Julian Alaphilippe bombing around on off days on a TrekTurbo Creo SL (complete with yellow bar tape and bottle cage to match his jersey) a few years ago.
