The Jet 9 is a straight-lining, 120mm charger from Niner. It tackles rocky, high-speed terrain with authority but struggles in the turns. Nimble and playful this bike is not. Stable trail manners, a solid pedal platform, and a comfortable cockpit keep the Jet 9 efficient enough for all-day epics. Those in search of a quick, light and nimble bike in tight corners and a playful, fun-natured character should look elsewhere. As far as value, the Jet 9 is middle-of-the-pack, offering plush RockShox suspension but lacking a dropper post.
The Jet 9 is best suited for all-day epics and high speed, technical trails without a lot of tight corners. Because of the efficient pedaling platform of the CVA (Constant Varying Arc) suspension, the Jet 9 also works quite well on flatter, more rolling trails where inertia and momentum give an advantage to 29-inch wheels. Riders seeking a more fun short-travel option should check out the lively Ibis Ripley LS. Want to step up to a chargey mid-travel option? The Santa Cruz Hightower can ride a huge range of terrain.
