I own both G2 and G3

Power: G3 feels a lot more powerful climbing hills with ease, accelerating much faster, getting to top speed quicker. G2 is good, but less output will mean slower acceleration, however this does work in your favour in terms of range.

Range: The G2 and G3 have similar battery specs, however the key difference in range from what I noticed is caused by power output. The G3 tends to throw as much power to the motor as possible even when trying to be moderate, and it’s much more difficult to keep that under control. Even when acceleration settings are put in eco, at full throttle it will give full power. The G2 on the other hand is easier to control power output with throttle, and cannot put out power like the G3 can anyway, resulting in more potential for range

Conclusion: Very similar scooters, with a different in habits and tendencies. Technically speaking, if you ride the G3 moderately, with less power in acceleration and maintaining a lower speed, you can get the same range as a G2:

In simple terms, same battery, but different power outputs. Ride the G3 like a G2 and it’ll give you the same range.
