I have a 20" folding bike (Bike Friday) that I'd like to electrify with a Bafang G311 hub from Grin. They recommend a fast wind (10.5 rpm/V) for 20" wheels which they sell with a 36 V battery:
36 V * 10.5 rpm/V = 378 rpm
But I want to use a 48 V battery because I have a better source for those, already have a charger, etc. So I'm thinking I should get the standard wind:
48 V * 8.4 rpm/V = 403 rpm
Does this make sense? Or is it better to get the fast wind *and* 48 V. For what it's worth, I'm a pretty conservative ebike user, always pedaling, just trying to extend my range and sweat less going uphill. Thanks!
