Short answer no. don't get it.
Simplicity in design, yes, great. But, surely by definition an all terrain bicyle was a bike that was designed to go as far as possible , both up and down hills,over mixed terrain before the rider would have to get off and push. so if the frames light but so insubstantial that it folds on the first kerb, or so heavy you get a chairlift to the top of the hill, its not a mountain bike. if you fit tyres that are fine on road but won't pull you through the gloop, its not a mountain bike, or brakes that woon't stop you on that mountain decent in the rain, its not a mountain bike. so for me, with mortal legs and ability, not having the option to drop into that 18" bottom gear is going to limit performance and detract from the original purpose. and the bike becomes something else other than a mountainbike.
