Hello from Down under 👋, I'm building a full suspension fat tyre ebike so I can evade kangaroos while I hunt drop bears 🐻.

Couple questions, I will be purchasing a bafang bbs02 and I'm wondering which chainring to go with, I watched a couple of Johnny's videos and the 46tooth seems to go alright but not sure how gearing works really. Is there any advice on this set up?

This is my bike I've ordered, any advice mu h appreciated
