Marcus, which Bafang mid drive are you planning to install, a BBSO2B or BBSHD?
Still don’t think you’d understand the nature of e-assist. Those motors can continuously put out 3-4x more power than you.
I live in mountainous terrain myself and have no problem climbing the steepest hills with road gearing, while loaded down with over a hundred pounds of cargo. Never even use the three innermost cogs of the 11-28T cassette while on the inner chainring.
Edit: The
TSDZ2 from EcoCycles is available with multiple chainrings.
Also, if you’re concerned about not having the oomph to make it up 25% grades, maybe consider adding a front hub drive as well. Bafang makes them for
fat bikes in 20”/26”, 500/1000W. With dual drive you’d have no problem negotiating the steepest gravel roads. Only issue (other than cost!) would be mounting a second battery, but a pair should easily fit in panniers hung from a rear rack.
