Thanks for the quick reply Dom.
From the photo it looks like it's the 350w version from the stamp on the bottom, is that correct? I can't quite make it out but is there also a manufacture date on the stamp?
I stripped, cleaned and re-greased my 3yr old motor last weekend but I'm still getting an annoying clicking noise while pedalling but only when the motor's not providing power.
I'm giving it a good test this week to see if it improves but am tempted to get a backup motor just in case so I'll let you know.
Thanks,
Phil.
