Hey everyone,

I’m working on a Luckeep X2 ebike (48V, 750W rear hub motor) and my planetary gears are completely worn out.

The gear is labeled: JB500W-1

Specs: - 36T nylon planetary gears - 608 bearing inside - \~85mm clutch assembly - Parallel key shaft (not splined)

I attached pictures of the gear and clutch.

I’m trying to find: - Exact replacement gears OR - Full clutch + gear assembly that will fit

I’ve seen similar kits online but I’m worried about: - Wrong clutch direction - Wrong size even if tooth count matches

Has anyone replaced this exact model or knows a compatible kit?

Appreciate any help 🙏
