Lol drill and welder that is all what u need to fix bolt problem. I was have the dame x3 😂😅

Well done. Thanks for taking the time to share. The 3rd, slightly heavier wire, is for the low fuel warning light. -Greg

Iv got a yose 350 hub with only about 200 miles on it but iv noticed theres a little bit of play in the bearing on the cassette side ( wheel has slight movement and tapping when holding and shaking 9 and 3). Being a sealed bearing can they be tightened or is it a new bearing job?

Work on all bms?

Do you repair cypher battery or do a test having a problem thanks

What size are the gears?

Were you based?

Where about are you based as I neeed the same job done for my bike

Always wanted to see inside one of these! Thank you. Rather than shelling out the €622 for the battery/controller, might it be possible to replace the controller with a KT aftermarket model and recell the battery? I appreciate connectors may need to be changed…and finding a controller small enough to fit into that area may be impossible…it’s just that I’ve been running a DIY range extender on mine for years and that was also supposed to be impossible due to the CANbus…would appreciate your thoughts, and thanks for a great channel!

What is your planetary gear removal tool called? The thing that is like a tripod that pulls it out of the motor?

i watched this twice & i've fixed my hesc motor now after a solid weeks worth of fucking about . the clutch needed freeing up . the metal piece attached to back of planetary gears . by the way your hands act as sponges and absorb all that chemical lube . just like Vaseline is petroleum based & people rub it all over themselves willy nilly. that shit is flammable as fuck

mine is doing a similar noise to the left side but wheel spins as normal when motor is not engaged but soon as i peddle even with motor off the noise come back also my disc brake come loose as soon as it started i thought that was the noise till i tighten it back up so im thinking its the bearing closest to disc brake has given up after 3 year/ what are your thoughts?

a well put together pack tidy protected even had the glands for the cables , shame for the cheap cells inside

Meanwhile back at the customer's home, his wife is asking him if he has seen her charger...

So let me get this straight, you didnt try to repair the cells or replace them... declared it "unrepairable" 😂

Nice job , question where can i get a replacement wire

Mate, I think those cells dont have enough amps on discharge for that motor. I am working on the same bike and had to use same lifepo as that motor gulps 20+ amps

We can all learn from videos like this. So, thanks! But, I do hope that you are not repairing other peoples bikes professionally! Never, apply power to a seized motor! It will weaken the windings. Don't use WD40 to clean bearings! It washes out the pre-packed grease in them.

Exactly what is up with my bafang rear hub motor and i haven't took it apart yet

Nice easy one ☝️ 😁

simple fixes are the best. customer error lol

I see, RTFL was missed.

Extra plug is for an ANT+ connector you can buy for the older X35 system & also its a PAS connector for the cadence sensor on the rear ring of magnets

If you are going to try to make money on youtube, get a proper set of circlip pliers!!

Low quality cells have caused this. Never had this issue with LG or samsung unless they have been seriously abused.

great video as always ,i just built the same battery for a aovo pro used a bigger bms though ,

Hey mate I have a fiido d11 and I'm having same issue could I use a 36v himo z20 wheel on instead

Can you reuse any of the good cells?

Did your old pins fried like you saw fire? I washed my ebike yesterday. Used a leaf blower to dry the bike and then swapped the battery. Let it dry about a good 7 hours after. Tried to power on the ebike. It wouldn’t power on. Removed the battery thought connector were just fried cause battery mounting plate was black. Big mistake using the 2nd good ebike battery I had put onto that burnt plate. Didn’t think much about pins until I saw fire coming out of the battery pins. They got damaged and melted. I tested both same batteries on a brand new clean working battery connecting plate only to see fire spark because battery pins were damaged. 🤦🏻‍♂️

I was looking up price of cells here in Australia, that and knowing which cells to buy from aliexpress and not end up with crap, so hands down agree, best to replace the scooter.

even amount of leaky cells, I wonder if the Bms didnt do its job and the charger was overvolting the cells

Always interesting to watch

Hi. Thanks for posting. Very informative. I’ve gotten hold of new fuses and was wondering how you desoldered it. For the life of it’s not budging. TIA.

I just replaced my controller, all works well. but i am now having trouble placing the controller inside the compartment to line up the screws. Its like the new wiring is stiff af and doesnt allow room for the controller to be seated properly inside. All wires are thru hole and squashed up next to battery. Any advice?

The Swytch kit is a road-legal, 250W, front wheel motor kit. This rear, 500W wheel is absolutely NOT part of any Swytch kit.

That's an ace explanation and video. Cheers! What will cause this on a motor with less than1200 hours? Am I pushing my bike too hard?

Hey there, i just subbed, i really wanted to know that, once this hall sensor magnet issue occured, does the motor act glitchy and wont spin when start from still? the story is: I just bought a second hand lightbee and after a short test run, the motor suddently failed, holding the drivetrain making loud noises,i stopped completly and give throttle, no power, i then give the bike a bit of push then give throttle, power comes on but wasn't fluent, sort of glitchy and like i said, fighting the drivetrain making a lot of noise, the chain was dancing like crazy, but however if i keep pushing the throttle it will actually accelerate but generates lots of vibration, i have no idea how electric motors works but with a bit of research online and seeing your video, i have a funny feeling that im facing the same problem here, I HOPE i made myself clear, excuse me for bad english, would you please help me by replying😊❤I also wish to know what could cause this failure and how to prevent it, thanks a lot

Hi, i have the ado a20 bike with the same battery. After being stored for over a year the battery wont accept a charge.. its not flat, still reading 36v. Stripped and tested individual banks, all are very similar at 3.6 v each but still wont charge. Would it be the bms? Thanks

You would wash your nails for the movie. No kidding.

Is it just me or the video has no sound?

Deans connector is the name of the 'plug'

Why not use lifepo4 again. Its quite save if you compare it with ion. Edit: who in the right minds solders on a lithium cell...

What a wild looking prototype e bike. I bet that drive gear makes so noise when running at speed. A lot of work to design and build that e bike.

That was very interesting , couple of hoverboard batteries in series and it’s back up and running 😁

I've got a motor and I've got a tester. Seems like the trickiest part is connecting the two. Everybody on KZfaq seems to have some kind of adapter (possibly/more than likely handmade). Do you know if anyone has a good video on all the ways an ebike motor can be hooked up to one of those testers?

Dont get anything with Mahle in it , no customer support and products that fail after very little use - a software update killed mine and nearly £1000 to get it fixed

i recently built a 10S battery with BMS, which Voltage should i read at C- port while not charging? The client was surprised to see same voltage as battery pack on C- port, because he has some BMS that read 0V at C- port

Loving your vids! My e-bike battery 10s2P died after no use for a long time. Bought a new battery pack to swap over. I noticed on the new pack the bms has wires coming out of the C1 terminal and not the P1? Is that ok or should I swap and solder them on the P1?. I don’t believe the e-bike has regen and this battery pack was probably designed for an e-scooter. Thanks bro!

I believe regular scheduled maintenance is the key like everything else. Did you get it used? That thing went through hell!

Very perfect Timing , i got one of this x35 systems without the Bike , it was my first time to view a Controller inside the Batteriepack 😂 , now i can do what i want , but first i see a purple led and the App tells me 1 cell is down 😊 ..its confusing how small it is
