100kv or 120kv

9.55/kV multiplied by motor current gives torque so you need 20% more motor current with the 120kV motor, but it has the same torque capability. This means that if you have an esc that can output enough current the 120kV motor will work equally well but give you a bit higher speed. I’m 100kg, have used both 100kV motor and 120kV, can’t say i notice any large difference when riding. I rarely go full speed though so the extra speed isn’t what i focus on. - @Larsb
