If you're not planning on doing a lot of off-road stuff, i think you're better off with a cruiser. Be careful, a lot of them are heavy (hard to lift) so you might look at hybrids, they are the closest to what bikes were like when I was a kid. I don't know what your price range is like, but there is a woman who started a business producing bikes for larger sized people, her bikes are nice. I like her "news girl"
