As I've said, it depends on what "your" definition of riding and off road means. I could care less what I look like turning a bike around. I don't need to look all spiffy in thousand dollar gear and be able to do a donut to turn around. So it will take me a few minutes to dismount turn the bike around and go back the direction I came.
I think what many people were saying here is that a 30" inseam is not a deal breaker for this bike. As long as you know what your skill level is, where you will be riding the bike and know that you will occassionally drop it then get the bike and have fun.
