Hi everyone, not sure if I have posted before, but I am having a problem with my chain skipping over the small sprocket on bosch performance line CX on a 2019 haibike allmtn 6. Guessing I did something wrong as today I removed rear wheel to set up wheels for tubeless and when I got it all back together the chain was not engaging on the small sprocket and was skipping over top of gears. I did not bother releasing the clutch on the derailer to make it easy to remove the wheel, maybe the clutch got engaged somehow and I need to re check that?? I did remove and clean up the small retainer the chain goes through that is directly over the tiny sprocket after I had the problem, but that did nothing. I figure it is likely something I messed up and someone here might know what I did. I can try local bike shop tomorrow, they have a couple of scott ebikes and I think they have the same bosch driveline.
I might be having a seal issue with the motor, but doubt that could be related. I got the bike in late Nov 2019 and got a couple of weeks of riding in before a major foot surgery that kept me on crutches most the winter. About a month ago, when I felt brave enough to try a light ride, the motor was very loud for an easy flat 20 mile mostly paved ride, whirring, grindy noise. When I got home I sprayed the smallest bit of Triflow lub into the bearing area on right side of crank and the noise went away. I have only been able to ride a couple of rides since as I am barely able to wear shoes still post surgery. Bike only has about 140 miles total and I have never sprayed a hose at it, just hand washed it a couple times carefully with a washrag. I stored bike in climate controlled garage upright over winter. I live it desert SW of US where it is dry, maybe I bombed a couple mud puddles last fall, but I try my best to avoid them. Hoping I am not having seal issues, but kinda think that is happening as today I got a dry rag into the seal area as it was pretty dirty and the dirt/sand was mixed with a pretty heavy looking lube which I can only guess came from the inside of motor. I use a very light and dry chain lube to keep things clean, only lubed it twice now and always wipe it down after applying. I thought I would mention this issue as I know there is a seal problem with these motors. It would be under warranty, but nearest shop for haibike is couple hours away and I mail ordered bike from out east.
Thanks for any help! I have enjoyed reading some of the posts here to learn about the bike, seems like a great bunch. I am enjoying this bike and while being laid up, I bought a 2017 Bulls cruiser bike that had 4 miles on it and have been using that on pavement more last few weeks as I am still recovering my foot. The bulls is very nice with the first Gen Brose motor and 8 speed shimano afine rear hub w shimano disc brakes. Not as powerful as the bosch CX , but silent, smooth and easy to out pedal the limiter without feeling the "anchor" like I do with the drag of the bosch. Loving the ebikes!
