hey so, im not really commuting to a job....but i live half time in the suburbs/half time in the city. I have no lisence, and public transportations becoming very expensive. I know how to ride a bike, and dont mind riding long distances, I'm a pretty good rider. I've always used my older brothers bike, but now I'm looking to buy my own especially since all my friends are getting their lisences and thats not something i can really afford right now. THe problem is I know nothing about bikes, i now use my brothers iron horse mountain bike but hes taking it to college with him. where do i start? any help would be appreciated!
