User Notes

This version was only very briefly available in the app according to several accounts.

It likely had an issue and was quickly pulled before Ninebot ESX DRV 1.4.7 was released, likely in a similar manner to the Ninebot Max's BMS 1.5.3 and BMS 1.5.5.

There is also a DRV 1.4.5 for Ninebot Max.

Users report that the amount of stopping power applied to the front brake was lowered with this version.

Users also reported that when you are hitting top speed it will automatically apply the brake and lower throttle for about 1.5s.
