Honestly,

For a kebun bike, something like a kickstart kapchai or adventure kapchai like an Aveta or Pg1 would be perfect. The basic Aveta Ranger can be had for under 3k nowadays. Its cheap transport.

Electric scooter batteries will also drain with time.

Storage not an issue...just mount a cheap small top box... any time bigger than the underseat storage on an electric scoot... electric scooters usually have minuscule storage as the batteries take up a lot of room.

On less then perfect roads, small scooter tyres can be a handful compared to regular 17" on a kapchai.

And if you have electricity supply where you park, you can always get a cheap trickle charger or install a battery disengage switch.
