I have a carbon comp and no problems with heat and have not heard of any, also you are correct. Once you get a levo everything else just collects dust lol
i have 130 and no problems. I only have it showing the battery percentage. originally had the ebike from garmin IQ and updated that and they have a new specialized specific app. Does what I need
as a fellow heavy weight I have never drained the battery all the way down., I ride 99% eco. I usually ride 2 plus hours and have over 50% left after ridding
