Hi there. I've got an old Keyde 26 inch front stealth hub complete with wiring, display, 2 bottle batteries (small and large) and charger which actually works fine except one drive roller has a ding in it so it clunks when in use. I've upgraded so don't need it.
Pictures are of the kit installed, bike doesn't come with the kit

maybe you've got a similar setup but need the bits? I had the idea of welding a fill in the roller and grinding it down to fix it but don't have time.
Make an offer- the batteries alone are worth a fair bit

Note: the guys at Sydney Electric Bikes sell second hand spare rollers but are pretty useless at getting back to you. If you hit them up in person maybe you'll get a better result
