How to avoid getting ur scooter stolen

I started going to a boxing gym a bit far from my home,people in the area are mostly very poor so leaving a kqi3 pro there is basically just like asking it to get Taken,now i'm wondering how to avoid it getting stolen,i finish my session at 10pm so most shops are already closed,meaning i cannot give it to some guy there and i cannot just leave it inside because you can easily see it from outside,you'd just need to carry it upstairs,even with the lock mode,people here will just push it then take off the bluetooth thing inside,i do have a bike lock but i don't see where can i put it,it's not designed very well for this imo,as for school or coffees etc i generally take it in with me, it's a pain in the ass because of it weighting 18kgs but i can't do otherwise
