I would like to get into cycling. I've never really been into it before. The most I've done is ride a bike when I was younger. The problem is, I have no idea what kind of bike to get.

I think I would mostly be using it for exercise, and I'd usually be pulling a trailer with my two year old. But I'd also like to be able to do centuries (not right away, of course) and other distance rides. And maybe an occasional sprint length triathlon--but honestly more just for fun, and not competitive.

The other problem is that my husband has no idea how much bikes cost. He thinks we can go over to Walmart and get one for around $100. So you can see, I'm going to have to start out with something relatively cheap (I do know $100 is NOT going to cut it), and maybe once he sees I'm serious about it, someday I'll be able to get something nicer.
