If you want more technical detail, this thread has some good stuff but basically:
The motor current is not the same as battery current. You do need motor current for torque. But you only need high battery current when you’re using high torque at high speed. IMO yes that battery will be plenty capable, they’re good cells and lots of em. What kind of speed do you want to aim for?
I’m 110kg, but because I ride gently I get better range than people much lighter than me who ride more normally
