Wanted a mountain bike that was competent but not one of the super expensive models. Nor am I into the bone breaking adventure I see on demo videos. Did some research and came up with some potential candidates. Stopped in the Giant store. Greeted by a knowledgable and customer focused staff member. He listened and then presented two different models for me to examine and decide on. Took the 2013 Revel for a short test ride. It just "fit" so I bought it. I had looked at some other brands and models and this just felt much better. And, to me, fit is the most important criteria separating makes and models that are otherwise suitable.
Today took it for its' first ride. Could not be more satisfied. Shifts very smoothly. Low center of graviity makes it stable but very responsive, changes direction at a thought. No need for horsing around. Brakes are smooth and very effective. Smooths out ruts, pavement breaks, etc.
Only downside is that frame design prevents mounting more than one water bottle. Very minor and can be worked around.
If you want a fairly inexpensive fun bike for general use give it a look.
