So I've been trying to change the inner tube to this bike because it's been messed up for so long and I don't have a car and I've been wanting to use my bike but I don't know how to change it, I don't know how to get it to a place to change it or I don't know how to find someone to come to me to change it. I looked up the prices online to change the inner tube and they seem pretty cheap $15 or $20 but I just don't know how to get it there or how to change it myself. I have no tools, no knowledge how to change it and I don't really want to mess it up, I usually do things like that myself but I'm terrified of poking a hole in the tire or something. Can you guys please tell me what I need or what I can do?

Also if I decide to get it fixed should I buy the tube to go get it fixed or just let them provide it?
