The motor is a Bafang 8FUN. I opened it up because it sounded and acted like the gears were slipping.
It looks OK inside. No sign of a problem. Could the gears be slipping although no obvious problem or is it
something else? Ideas? Thanks.
 
It can be issue with a clutch.
I've had similar problem.
My clutch looked similar to ball-bearing and looked fine.
I've applied there extra grease and slipping problems had gone.
