Hi, I'm a total newbie and just looking for a bike that I can ride around my neighborhood and for an occassional camping trips. My budget is limited so I'm looking at used bikes but I don't really know the values so please advice on these two:

I'm really short so I think with these will fit me since they are 13" frames.

Thanks!
