are you starting in that cog? are you spinning? if you work too hard in that cog instead of spinning you will wear it out faster. but even then you should get a few thousand out of it. on our bosch powered tandem we would cruise in the 9th cog and it would skip around 2000 miles.
no it sucks. I had them change to a nyon before I brought my bike home. but its not hard to add a nyon yourself. you just change the mount it use the same wires. I like the nyon as you have a lot more info on the screen its mounted better. the mapping is ok as long as you make your own maps...
well no to most of it. no way you would get enough power to use USB c well any power really bosch just does not do that and phones just keep needing more power. but the nyon will integrate with apple health finally. the kiox should too but it is abandoned so I would not buy it.
sure been around for a long time. https://www.universalcycles.com/shopping/product_details.php?id=29754&attribute=68057&gad_source=1&gclid=CjwKCAjwl4yyBhAgEiwADSEjeDlTJzZAwpuOf4chH7VuqzyMsx6ldLxL9RN6qV0lzPfbsmwg4l89JRoCIfoQAvD_BwE
