A few months ago I posted that our Sprint motors were rather noisey, however, a short time later, because of other things we were storing in our wooden bike shed which felt rather damp, we invested in a dehumidifyer which we run overnight on the low economy electric rate. I'm convinced that this has had a good effect on the motor of the bikes as they have been almost silent for a while now. We live next to the sea so the dehumidifyer collects a fair bit of water so maybe the motor was damp before which caused it to be noisey.
Just thought I'd post this in case it is of help to anyone else.
Kind regards
Jeanette
