Ok, so i am in my second year in college in Boston. And I have decided that i need / want to get a fixie. I am on a very tight buget, so keep that in mind. I want the bike to get to classes and to just plain get around the city (and maybe get in shape).

First, my father has 2 or 3 old road bikes (which i should be getting specs on them tomorrow) which he would give me. I am guessing that they are pretty heavy. One is prob 15 years old and never ridden, and the other(s) are prob around 30+ years old. second, i am 5' 11 3/4" tall and have an inseam around 83 cm (33").

So, will one of the *free bikes from my dad work as a conversion bike, or should i get a different used bike? What size should frame should i shoot to get?

Another thing i have heard is since the boston roads are so bad, i need to get heavtier tires...is that true?

(p.s. this is my first post!)
