Is it a clutch or gear failure

[SRS]

Hi all

It’s been a whiles since I visited this forum and I am only familiar with crank drives.

A friend of mine has a folding bike with the following front wheel hub motor.

Seems to lose its drive under load. Ie: with the bike raised off the floor, pedals rotating. The motor drives but the wheel can be stopped by hand.
Some mechanical noise is still heard as the motor is still turning internally.

Is this the clutch slipping or stripped gears?

Either way, if it is the motor does anyone know where to get a compatible version?

Any advice appreciated, Ian

clutch slipping. Clutch and gear reduction are built into the same unit, to be replaced as a single piece.
Open the motor and take a look first.
