Has anyone narrowed down what the reason is for all the bad noises and bearings? Is it inexact tolerances on axles or whatever? Cos some motors make bearing creak straight out of the box while others take 5000kms

I have an external battery on my e8000 bike. The motor keeps cutting in and out on climbs in trail and boost. I am guessing it is bad cells in the battery preventing it from sending full voltage to motor.?. Has anyone had success in accessing BMS voltage info? Has anyone succeeded in...

Has anyone been able to narrow down what the design flaw is? This new motor is so loud it's embarrassing, especially standing up pedalling.

I wish it was something other than the axle bearings creaking but it isn't. Honestly, it doesn't bother me that I need to replace the bearings as much as the irritation at hearing it with every hard pedal stroke.

is that bad?

It is definitely not loose mounting bolts or loose cranks or loose whatever else. It is the familiar sound of crappy e8000 bearings creaking. The last motor had the same annoying creak with every pedal stroke.

sorry e8000

I bought a new motor and used stunlocker to program it. The motor fw is 4.3.4 but i don't like the power delivery. Can I update the firmware to one of my choosing using shimano's etube or will it update to the latest that isn't fully supported by stunlocker?

Seriously!! Brand new motor and the creak has already started. Shimano should be replacing these for free.

Thanks. Might use the old grease on the plastic gear and bosch on the rest

Also, is it normal for the clutch cog to have a little side play?

I've read so much stuff about grease that my head is spinning. I have some Bosch bdu classic grease on hand. Will I damage my unit using this stuff in my e8000? I did scrounge a bit of the existing white grease but not much and some of it is black and unusable.

Hi, massive thanks to the contributors to this thread! Without it I definitely would not have been confident it was possible to pull that circuit board around the axle to be able to remove the axle. Ages ago I heavily clipped my left pedal an went otb. It was so hard that it bent the crank and...

Can I just quickly confirm that the idiotic bolt that holds the spider on the drive side comes off turning right ie. reverse thread. Just to be clearer I'm talking about the one that needs the fc39 (or whatever it is) to get it on/off Cheers

Thanks!!!!!!

Has anyone tried Aeroshell 22 instead of this stuff?

OK, I have had this problem for ages. First, the RHS crank clicked at 12 o'clock position, now it creaks all over the place mainly whenputting the power on. Has anyone successfully replaced the drive side bearing?

I know what you are saying but it might be cheaper to fix it myself. Because i live in the middle of nowhere without a shimano dealer. At the moment it has stopped making the click/creak for the last couple of hundred kms so I guess it doesn’t matter

No but I’d still love to know what’s going on with it all. So I guess I’m going to have to buy two tools to get the lock ring off then crack it open and have a look.

Okay, it’s disappeared again after i laid the bike on its side and sprayed lube around where the axle enters the motor. Rode 40 kms and no click or creak or even any sign of a drama.
