raymour, unless you're biking on TRUE mountain bike trails, pretty much any bike will handle it. I ride my Verve (like a Cypress) and 750 (like an Escape) on hiking trails, some groomed and some not. They handle it just fine, even with tree roots -- you just need to be be careful. One of the biggest factors, in my opinion, is a high volume tire. The more air volume (not pressure) you have, the more forgiving the bike generally will be on mixed surfaces.
I think the Roam would suit you well, but you really need to ride one before ordering or buying. What other brands do your local bike shops sell? Every major brand sells a bike like the Roam, and you might find one from another brand that fits you well.
