Dirt Jump Mountain Bikes

In this installment, the dirt jump bike, these are purpose built bikes strictly for performing jumps.  These bikes have a much lower top tube and seat so it’s out of the way when performing tricks while in the air.  They also incorporate a stronger frame and wheelset when compared to a cross country bike, which they most closely resemble.  A dirt jump bike really cannot be used, comfortably, for anything else, because of the frame geometry it would be very impracticable to ride for any distance.  Below is a great article describing the dirt jump bike along with a picture of one.

“Dirt Jump bikes are a cross between a freeride bike and a BMX bike. Also termed as an urban and street mountain bike, it features a system that allows the biker to ride over obstacles, requiring a takeoff and an eventual landing. Features of this bike include fast-rolling tires, 4 to 6 inches of front suspension and hardly having any rear suspension. Oversized handlebars allow the rider to fully maneuver the ride, with extended rear cables to allow them to spin the bars without getting tangled with the cables. These rides also have a smaller frame, and have about 24-26 inch tires. The lower seatposts provide riders with much leverage so the rider can perform tricks without the seat getting in the way. Riders prefer this type when they perform tricks as it lessens the impact of the crash, and are much simpler in terms of components that need replacement during accidents.” (original article here)
