Customer Reviews:

Ben - Libertyville, IL: "I'm loving the Gravity Mountain bike I bought earlier this summer. The bike arrived in perfect condition, the setup was easy, the components are superior, and the ride is excellent. Thanks for a great deal on this great bike!"

A. C. - "Fast! I know that hardtails are faster than full suspension bikes, and this definitely confirms the impression. The bike is lighter and feels much more responsive…found that climbing little 1-2 sheer bumps is MUCH easier. ..usually don’t clean ALL of these bumps on my old Specialized (there are 5-10)..All in all, a fantastic bike at the price. It's a keeper...
