Bitting off more than I can chew.
Decided I'd service my ebike hub drive after watching instructions on YouTube.
Disassembled hub only to find one of the nylon cluster gears teeth worn down. Only thing to do. Find the parts on a Saturday
Found Phillipe in Cyberbikes and so helpfull. Long story short new set of gears, reassembled into wheel with very helpful instructions. We hope to see Phillipe at the Ashfield Bowlo soon
