My radster road blew a rear bearing in the motor/hub assembly after 1600 miles. The symptom was a constant squeaking and a tiny bit of play. I followed another guide on youtube for pulling the motor apart but it was for a different motor so I though I would post the bearing parts for those who are facing a similar issue and want to order the parts in advance.

The bearings Rad used were pretty low quality no-name bearings. I upgraded to quality NTN bearings on both sides even though only the smaller bearing was at fault. I hope to not do this repair ever again. You could roll the dice and get amazon bearings with the same size and specs below.

Part list:

(Size) (Sealed on both sides) (electric motor grade)

6002 LLU C3 bearing
6004 LLU C3 bearing

Seals, I would buy two of each because you could mangle them and it's cheap insurance
Rotary Shaft Seal 20x30x6mm
Rotary Shaft Seal 15x25x5mm


Happy repairs
