Adult bike for spare (The Camp AL1)

I had 3 in various states of disrepair but not able to ride so gone to landfill as no takers on freegle . So I could do with another in working condition for when my bike is broken down as I have no other way of getting round. If 26" I can replace the tyres and front wheel if necessary . I would buy from recycling centre for £20 but I don't know enough to be sure it's any good.
