one more thing, they are both rated power 500w. In 2024, there will be 750w version been released of M560, with 140nm, which is quite close to M620 then. That's a big temptation.
@@fironwoo I'm currently riding the M620 and the noise is horrible. I can't stand this noise anymore and that's why I put my bike up for sale. It's hellish to drive in nature with such a high noise level. I'm going to build myself a bike and currently I'm thinking of getting the M510. Smaller, but hopefully quiet
