squeak

Anyone else have this issue with Bosch motor? I found this video on YouTube (Not my motor). Mine is the Performance CX version and making the exact same squeaking noise.

After putting considerable mileage on my Bomber over the last few weeks I noticed a squeak developed and got worse as I road. The noise happened only during compression of the rear spring. The noise wasn't crazy loud but the fact that the bike is so silent makes any little noise noticeable...
