Vitus E-Mythique LT won't power on.

Try this tool.

But much better to turn down OD and tighten nut and not the bolt.

I went with a 13mm socket (I couldn't find a half inch socket to hand) and turned it back to just over 17.4mm.

3/8s drive socket. Half inch drive won't fit the top left bolt .

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.

weirdly, these are back up for sale....sports direct £2300 ish....no mention of a warranty etc though.

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.

 

[RonanGee]

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

Seems like you were right !

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

Sparking is normal, it is inrush current into controller capacitors.
You can use black antispark XT60 if you are not confident with sparks.
