I have had many bikes in the past. Mainly Mountain Bikes. And that is kinda what I am looking for now but I thought I would see if anyone has any good suggestions for me after I describe what/how I intend to ride.

First off, I am 6'1" tall and weigh around 240. I am a big guy. I want a bike that can support me but isn't outrageously huge. I like to ride on the street and on light trails. We have an old railroad line that was converted to a foot and bike trail. I also live near the coast and ride near the beach so salt air is an issue. I would like something that has the same or similiar lines as mountain bike. Any suggestions?
