The load comes from accelerating the flywheel from a standstill until the motor hits its max rpm and can no longer accelerate. Initially it'll pull over 100A, and drop to a few amps by the time it's at max rpm. There's no need to vary anything else.
Not sure about the belt drive, that'll need to be very tight to prevent slip and adds an extra unknown variable.
And they'll need way more than a 45A current sensor.
Good to see an off the shelf tool available though, should provide people with hours of fun.
