Hey all,

I’m planning on a rear hub motor and wondering what kind of compatibility issues I might run into when trying to fit the original bike’s cassette onto the hub motor? For example, do the cogs’ inner hole diameters vary a lot, potentially causing some cogsets to not fit onto the cassette slot on the motor? Are there specific size standards for the cogs’ holes? If anyone has experience with this, I’d be eager to know, thank you!
