Hi !
I plan to build a cargo bike (long john), with Grin All Axle on the front wheel (20“) and 2 kWh battery.
My goal is to have a bike able to climb properly up to 12-13%, and to ride to ~30 mph (45 kph) max, even when the battery is nearly empty.
Should I build a 14S (52V) battery paired with a fast windings motor, or a 20S (72V) with a standard winding ?
What are the advantages of 72V ? Only higher power ?
Thanks !
