Crank creak Bosch cx motor

[currymonster]

hi all
Need a bit of advice from you technical chaps.
I have a cube reaction 400 less than a year old and it has slowly developed a creak from the crank on both sides, more noticeable on the left arm. It is slowly getting louder and becoming annoying.
A Local cube dealer has had a look and can't find the issue. It's not the pedals, the crank bolts or the internal bolts that hold the motor. They say it could be the sealed part of the Bosch motor but that needs sending back to the Netherlands.
Anyone else had issues on the Bosch motor? I found one thread but that seemed to be the internal mounting bolts of the motor.
Thanks

I had similar noises from my Haibike urban with Bosch performance motor it was worse if I dropped down the gears, I tried to get it looked at under warranty without success because I purchased it in Europe anyway today I oiled the chain and the noises have stopped it surprised me because it wasn't that sort of noise ! Worth a try.

Is there any play in the cranks? Hopefully not. Mine got noisy and I noticed some movement in the cranks. Just under two years old. Replacement motor from Bosch under warranty as bottom bracket bearings had gone!!
Never had one with that issue before!!......said the retailer!!

I'd say that your dealer is incorrect, and that they might not have done their checks properly.

I'd suggest that you take the bike back to them, and request that they re check and tighten the motor mount bolts, and and re check the pedal crank bolts.

I very much doubt that a CX motor is going to suffer bearing failure within such a short space of time, and even if it had, the failure would not be a creak as you describe.

If you are anywhere close to me, I'd happily take a look for you.

think the best tools for a new bike is a crank puller and the lock ring tool/spanner.

then can just diy, not like its even hard to do

Thanks eddy appreciate that. About four hours away so a bit far. It's with a cube dealer at the moment so hoping they will get to the bottom of it. All that I have read indicates bolts on motor but they said they have checked them.

Sadly creaks can come from many places. I recall having one last year that I thought was coming from the pedal crank area, but after being driven mad by it, I eventually I tracked it down to the head set.

I'm certain that your issue is going to be just a simple to resolve.
