Good info, thanks Dennis.
Working on my winter bike here. I have about 1000km of testing in minus degrees down to -25C (yes, I know the specs don't give it so low), 15km in the morning and 8 in the evening, plus one 34km ride with Cruzer cart in the back.
Everything seems good down to -25C at least, haven't been out in colder weather this year.
Many many problems and fixes, lately only this power cable related problem.
