I reported mine to Canyon as well but haven't heard back yet.@Herder000 any updates on this one? After my last ride, I reported the issue to Canyon, and I'm still waiting for a reply.
It takes forever for them to reply, and I'm getting frustrated by the bad customer support.
When I arrived from the last trip, the motor shut down, and I couldn't start it. I inspected the battery and the mount, and I know that the battery was latched properly. After re-inserting the battery, I was able to turn on the system.
I still see some play in the battery even when latched properly, which makes me wonder if the connector mounted in the downtube shouldn't be adjusted.
I'm not sure how to do it, as it's buried deep in the downtube and I cannot reach it by hand.
I removed and reinserted my battery as well yesterday but to be honest it seems pretty tight anyway so don't think it's that. I went for a ride last night, after 15 mins, at the end of a very steep hill, it cut out 3 times for about 0.5 seconds each time. I stopped, and realised there was a little space between the magnet and the wheel (talking less than a cm) and I've tightened that up so it's right up against the wheel with no gap. The rest of the ride, about an hour, it didn't do it. Not sure that's solved it though. Will go out again tonight and see if it does it again.
I think your's sounds worse to be honest, I'll keep you up to date with what happens with mine though. Maybe we should start a new thread rather than dragging this one down.
