As all bikes, the frame size and fit are key to an enjoyable ride. Get the bike that feels right. Great bike for someone just getting into the sport and is unsure if you will like it. Great for the beginning rider. The suspension is fully functional, the derailers are low maintenance, and the bike is really strong outa the factory.
Frame is slightly heavy.
Low grade of aluminum is the reason for this. It was a great bike to teach me the ways of the trail, but now because my improved skills and desire to hit harder trails, im going with a higher end bike. I'll always remember my NuNu though. If there is any one weakness with this bike, it would be the Jett fork. Again, you are getting what you paid for.
