what chainring options are available? I ordered a fatbike with bafang max drive. but the chainring looks to large for offroad use. and the rear casette isn't optimal. the largest rear cog isn't very large.

Not helpful, I'm not interested in the assembly of the motor but the installation with all the electrical hookups.
