Segway-Ninebot Controller Max G3 The controller for the Ninebot Max G3 is the brain that decides how fast you go, when you stop, and generally whether your scooter will cooperate or do its own thing. If your old controller has started to malfunction, shut down, freeze, or give your scooter a personality of its own, it’s time for a change. With this controller, the Max G3 remembers what smooth performance, stable power, and rides without “sudden inspirations” mean.
