I take my Giant Roam 1 on local MTB trails often. They're not super technical trails, but they have their share of log piles, bridges, switchbacks, rough terrain, and hills and the bike handles it fine. That's one of the reasons I selected the Roam - it's skewed a bit more towards the MTB side than most hybrids but it still handles paved trails/roads just fine. Great balance for my needs.
