After checking my Tinnitus, anyone else experience a whistle, quite high pitched at a constant speed, usually around 40 to 50mph? It seems to be motor related… brush-less motor so not obvious causes so it could be a characteristic?
I’ve not noticed it but it could just be my age! if it is very high pitched.
I have noticed mine always sounds quite whiny, but not sure if that’s cos I am sat on the motor, not sure what is sounds like outside.
not heard a whistle the motor does make a loud ish sound at that sort of speed but I quite like the sound reminds me of the car from Joe 90
