Infinity Bike (new bicycle inner tube, bike seat adjustment)

Hello, I bought this bike from a flea market a few months ago. I had the intention to use it but I've never ended up using it and it's been sitting in my room, clamped onto the wall taking up space. I took it to a bike shop and got the bicycle inner tube replaced with a new one and they also adjusted the bike seat adjustment since I prefer a lower BMX-style seat adjustment. I'm throwing in a Metal Poster of the The Lost Boys. It's pretty small. If there's anything else I can find, I can throw it in.
