SWEET HANDLING Gravity has really dialed in a trail-proven geometry into this phenomenal ride. The handling is very responsive and yet stable. Singletrack and switchbacks are all handled with ease. Slow speed and high speed, technical and flat-out hammering, you will go faster because this bike is so capable.

Gravity MTB: 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...
