I rode the bike home, it worked very well and very fast, even with some air missing in the tires.

I have 0 tools, some maintenance info I learned online: mainly washing the bike w/ warm water, a cloth, and homemade organic soap (I added the last part) and oiling the bike using specialized bike oil (though I'm wondering if there are any greener alternatives to using oil), and, as far as adjusting goes I'd have to go through My Ten Speeds w/ my bike in mind. Good thing tomorrow's a day off.

Oh, and I have no idea. But Miami's a big city, there has to be one somewhere.
