One of those will work better on hub motor?

Thank you.

first one is a SINE wave, second one is a TRAPEZOID wave controller.
first one is silent, second one not. first one is new technology, second not.
i would always go for the sine wave.

Thank you izeman!

I asked why,I could not find the type of wave used by the old one.

Sometimes sine wave is not as efficient.
