Gravity has really dialed in an Urban-proven geometry into this phenomenal ride. The handling is very responsive and yet stable. Alleys and parking lots and slaloms are all handled with ease. Slow speed and high speed, technical and flat-out hammering, you will go faster because this Dirt Jump MTB bike is so capable.

If you love the ride of the Dirt Jump MTB bikes that cost upwards of $700+; you will love the ride of this Gravity Dirt Jump bike for about half the price
