Ninebot Max Motor Generations

Late in 2020/early 2021, Ninebot released a second version of the G30/Max motor.

Gen 1

The Gen 1 motor's SN (Serial Number) begins with a 5 or a 6.

It has better torque and hill performance, but on stock voltage, it will only go up to 20mph/30kmh.

The top speed also drops rapidly with the battery level.

Gen 2

The Gen 2 motor's SN (Serial Number) begins with a 9.

It is capable of faster speeds with worse torque/hill-climbing ability.

Some users have reported 22mph/35kmh+.

This battery is less prone to speed drop with battery usage.

Gen 3

The Gen 3 motor's SN (Serial Number) begins with an A.

Not much is known about this motor currently other than that it does not work with earlier firmware at the moment.
