Hi and welcome to TE!

It really has less to do with your being a new biker than it has to do with various other things like:

What's your budget allow?
What kind of riding do you want to do? (on paved road, gravel/dirt roads, mountain biking on trails, just easy suburban riding, long or short distances?)
What is your local terrain like? (flat, hilly, city, rural?)
Are you old/young, in shape/out of shape?
Have you ridden bikes before?

There is no one bike for all different purposes. You need to tell us all more details.
