Woosh Knocking noise on TCM motor bottom bracket.

[paxo22]

Hello,
there is a knocking noise coming from the bottom bracket of my Woosh Krieger. The Krieger has a Bewo mid-drive motor, also known as a TCM motor. I can't find any information on it online.
It has gradually been getting worse. It only happens in the mid gears, 3, 4 and 5. The motor/clutch/gear-case assembly is not loose on the bottom bracket so it must be the bearings. Also there is a little side play between the crank axle and the gear-case assembly. I have done 4,500 miles.
Is it possible to get replacement bottom bracket bearings for the Krieger? Are they cup and cone or caged bearings?
Thanks.

Contact Woosh to see if they can service it or still have spares on the shelf.
Like Wisper they are pretty good at sorting customers out.
