On Sunday I will bring my new road bike from the shop. I do not have a car and the bike will give me freedom and mobility beyond what public transit affords me now. Eventually - maybe in a week or so - I will begin commuting my bike, which will add to my daily exercise, which is a very good thing.

But I am afraid of falling or colluding with a car or another biker. I am not very coordinated and I have fears. Will I overcome them?
