If the motor was drawing a constant 1200w why did the wheel speed vary by a maximum of 1mph (5%)?
Even with different wheels and different coefficients of friction of the braking surface?
Even when the pads lose their effectiveness and rim temps dropped significantly wheel speed hardly changed?
No way was that braking system absorbing a constant 1200w.
They are either flat out lying or somehow got their measuring wrong.
Regardless measuring force/torque at the caliper would of been a much better way of getting a power reading than working off the drive motor.
