I'm pretty sure I just used a 1/4 inch drive socket and it fit fine. I don't remember having any trouble removing the motor and I have done that to 2 different E-Mythique's.

Great. Will you also turn back one 13mm socket for me and shipp? Will pay.
The nut is 13mm, no?
Other solution is just to cut a little of carbon around nut with a dremmel.
I have one of these coming in. Reading from everyone's posts, seems like the thing to do as soon as I get it is:
1. Split motor, apply conformal coating to the PCB
2. pack drive side seal with diaelectric grease, put motor back together
3. Use some VHB tape to extra seal cable ports etc.
If i do all of those things chances of problems are less high? I couldn't pass up on how cheap this was, figured if i can make it more bombproof it will be a great bike. Let me know if there are any other tips you guys recommend

Still haven't had any issues with mine. It's not guaranteed you will haver problems, but obviously anything you can do to mitigate any potential issues can only be a good thing !!!
Mud guards too ! There is a thread on it.

Sorry only seeing this now. By the time you paid for shipping it would probably be cheaper to buy a slim 13mm socket

I still can't turn our bike back on. We went down the possibility of a wet motor route and ordered some AliExpress replacements. I opened up the motor and it was immaculate inside so I didn't go any further. Now I'm thinking it's a power issue. More info in next post.

So maybe it's a power issue. The battery is fully charged and on the blue light. Not in sleep mode. But I did notice that some of the pins on the battery connection in the bike look eroded. And if I look into the battery one of the connections looks burnt. When installing the battery there are lots of clicks from the battery slotting into the frame and the battery latch but I thought I could here a sparking sound too. I removed the connection and plugged it into the battery and confirmed that the battery is sparking when I plug it in. Not sure where to go from here. Possibly try to replace the male side of the connections that lives in the frame.

Mine looked immaculate inside too with no water ingress visible at all but the circuit board still needed replacing for the motor to come back to life. Since you have the parts anyway I personally would change the part and see if that helps.

Ok, so shes back working for now 
I replaced the power board and she fired right up. AliExpress purchase. Battery is charging in the background.
I also got a new cable but didn't use it as the original has added sealing behind the block. New cable had none.
The battery still made it's little spark sound when I put it back in the bike so inwanst expecting much. Either the board worked or the battery just decided to play ball again. Fingers crossed
Also this tool to remove the chainring isn't great. A socket style would be much better and I learned the hard way that it's a left hand thread

Just glad its back working. I really like the bike but this problem does seem a common issue.

Anyone who has fixed one of these near the Surrey Hills.
I think a wet session in Redland woods might have killed mine. Worked fine during the ride, but now 4 days later when I try and start it up again... nothing.
Battery seems fine and can put it in an out of sleep mode. There does seem to be some sparking when the battery goes in which I never had before.
Or any repair shops that work on Bafang? Most of the local bike shops only seem to be Bosch and Shimano.
Thanks!

Mine died today with Error Code 27 briefly then permanent Error Code 12. Changed the display and it went away. Now returned again.
Internet says needs a new controller. Anyone had this?
Could it be water on the connector board in the motor again?
Cheers

@blacklab14, I'm not local to Surrey Hills. But if it helps, I'm near the Birmingham area. pm me with the details of what happened and I'll try and give you guidance on how to get the bike up and running
@Mikefiver, same thing as above. I've become somewhat the Bafang guy in the UK. If your motor is under warranty (and you can prove this as the original owner), i can either swap the controller or get a replacement motor from Bafang. PM me and we'll go from there

Thanks Neeco, not sure how to pm you? I’ve knackered the warranty after repairing it a few months ago. Repair was a replacement connector board - original was corroded, motor had water in it.@blacklab14, I'm not local to Surrey Hills.

Might be same again although different fault codes?

I see.
Its difficult to diagnose the motor without inspecting it in person, as I have the Besst Tool and my own account with Bafang. But I can aid you in identifying whether the motor is the problem.
So i'd like to ask you to perform a quick test.
Remove the battery from the bike. Then hold the power button on the display remote whilst installing the battery. Essentially, you're force-starting the system.
If the bike turns on, then we can confirm that your controller in the motor is working.
If it doesn't turn on with this method, then we know that the route of the problem is the motor.
Please kindly let me know if it turns on or not and we'll go from there
There's a few diagnostic bits in the Tech docs thread, though sadly I've not really kept it that uptodate so there's no super conclusive work throughs.
www.emtbforums.com
I asked the mods to try and keep that thread "chat free" so it's easier to find information - hence there's little to no chat in there
Vitus E-Mythique Tech docs
General Bits for the Vitus E-Mythique : Fork Offset : 44mm (1.5" to 1-1/8" tapered) Shock Size 205 * 65mm (Trunnion) Link to Rear Shock on VR/VRS Bottom Shock hardware : 25 * 8mm (Fox code : 803-03-328 DVO code : 1429250-8 Both should be interchangable) Headtube : 44-56mm Tapered...

Took the motor apart and there are droplets of water everywhere particularly on the ribbon cable and the power connections inside. The connector board is dry though.
The controller is a bit damp but seems to sealed a lot better than the connector board.
The big bearing behind the chainring is rough and there’s play in it. Could be where the water is getting in despite my efforts to pack grease between it and the casing. Other than that I’m mystified how it’s getting in. The connector board on the other side is well sealed. Ordered new bearing and seal. Hopefully being dried and rebuilt will fix it

My E-Mythique decided to come up with code 36 a few days ago. Had a wet(ish) ride about two weeks ago, washed the bike and put it in the garage and full charged it. About 5 days later the 36 fault code appears on the screen even though I hadn't even turned the bike on or touched any of the buttons.
I've tested out the handlebar buttons with a multimeter and they all meter out perfectly ok.
When I can get it turned on, the up and down buttons cycle through the power modes ok.
It seems to be the power on and off press and hold function that is the only thing that doesn't do what it should. The power button with a short press cycles through the functions and will select menus ok in the setup menus.
The system powers up when the battery is plugged in, and sometimes will power off with the button, but then won't power back on. Then sometimes it won't turn on when the battery is plugged in??
The bike was bought in March 24 so should be in warranty but who will do warranties? I don't expect the new CRC to want to.
Having read through all the various threads in here I'm thinking that it is probably the crescent shaped connector board in the motor.
Any advice will be gratefully received.

i presume sport direct are just selling old stock....shame they seem so unreliable.
I don't think it's that they "so unreliable".
It's the usual Forum reflection of people join with issues - even more so with a lot of people who bought this bike who weren't previous EMTB'ers.
Which in turn meant no experience of "MOISTURE" ...
I've had zero issues with mine still - maybe I've been magically lucky !
When any of my bikes are wet - I DRY them. Like bake them ! (sh111t .. that pic is 4 years ago in the bike shed) .
People aren't as attentive to water ! no mudguards, stick it on the back of the car, shove it in the shed .. It's fecked !

I bought my E-Mythique from CRC in their sale last year. Although they were in administration, details on their website indicated that standard terms still applied to returns and warranty claims.
After only a few rides I started getting intermittent problems with the motor before it stopped working altogether.
I managed to contact CRC through their webchat. By this time they had been purchased by Frasers Group who said that they were not responsible for any previous orders or issues. I was advised to email the administrators at [email protected].
I received a reply 2 months later saying I could register a claim as an unsecured creditor.
In the meantime I contacted my credit card provider and explained the situation to them and provided all the information. They opened a case and within a few days had agreed to refund the cost of the bike through the 'chargeback' process.
www.ukfinance.org.uk
Within a couple of weeks the money was refunded.
I then came across the forum whilst looking to repair the bike. I took the motor apart and found that one of the boards was corroded. I ordered spares from AliExpress, changed the faulty part and it has now been working fine since.
Hopefully this info may help those of you who are having issues with their bikes. I have a word document which has more info on the "CRC in administration" warranty policy but don't know if I'll be able to attach it?
Also, thanks to all who posted on here with Info on repairing the motor, it's really helped me and saved my bike!!

I've converted them to PDF as couldn't attach the word documents.
The form was from the administrators and is to register a claim as an unsecured creditor. It should be sent to [email protected]
Like I said, I went through my credit card company rather than doing that.
