I'm surprised that all original firmwares were not protected at all.
I've tried to fix firmware of some cheap (but with good DAC and analog schematics) Chinese media player based on STM32 and firmware was protected by no-read fuses and only action possible in this case is to wipe flash, but not to read-out firmware.
And this scooter looks much more professionally-made and expensive product.
