MY7618 600W 36V 3000 RPM
These are small motors that pack an incredible punch for their size. They have a greater than 78% efficiency and come in sizes from 350W to 600w. This is an incredible amount of power for the small frame size.
This 600W 36V brushed motor can put out a staggering 1.74 Nm of torque at 3300 rpm. They are commonly retrofitted to scooters where they are used to replace the smaller 100W-200W MY6812 etc.
It's an incredible power boost and will allow you to change the ratios for greater power or speed, but its unlikely it would be a simple drop in replacement seeing as this motor is both wider and longer.
Still, where's the fun in life without a bit of modding here and there?
