its a QR code/sticker on your battery. I have had shutting off issues on my bike, and Shimano already replaced the motor once, and wiring Rosenberger connection twice, and Canyon actually sent me the pictures of the QR code that belonged to my battery flat telling me its a Shimano problem. I deleted after shimano replaced my ep801.
Its not a Canyon battery, they outsourced that to Shimano. That way they were only responsible for the frame failures.
On a side note, we sold a lot of these to friends, we are tied to motorcycle royalty. One of our friends bitched to Canyon, and they said they would start the buyback process. We are in USA. So what I see is that squeaky wheels are getting greased with the buy back. QUESTIONS are they going to use the 1/72 formula X months used, and pay us cash and have us dispose of the bikes. Or will they send out shipping containers with prepaid return postage? Im with the rest of us, but will wait to hear what they tell us on the 8th
