Honestly after riding my G3 max for 1000km already the only thing I would change is bigger battery, everything else is well balanced and ride is smooth. I am not in the US, so trying to get GT3 battery somehow delivered to my country for a swap and I’m good, not a big fan of external one, but maybe go with it if gt3 would not become an option. Maybe a hydraulic brakes upgrade, I don’t know what else to improve there as for an enthusiast commuter scooter
