‘The big problem is water’: UK ebike owners plagued by failing motors
Repair business is booming as owners complain of their units needing to be replaced up to five times
"Some mountain bike owners with fourth-generation Bosch electric motors describe how they had four or five – yes five – replacement motors fitted during the two-year warranty period. Owners of other brands say theirs have only lasted 800 to 1,000 miles."

Note that they also mentioned failed torque sensors, which is something everybody needs to know. According to the bush telegraph, if you park your bike next to your electric drill or anything with magnets in it, the sensitive torque sensor can get magnetised, then won't work. Have a search for Bosch Ebike torque sensor problems to see how many there are, mainly without solution.

I think the Kclamber cassette torque sensor has resolved that. I have it on my full sus bike.
There is no way that it can get wet in normal usage.
