Rider Feedback

If you were to imagine Pivot’s bike lineup as a professional football team - the Mach 5.5 would be the running back. With a stout build, low center of gravity, and brimming with pure athleticism, the Mach 5.5 is ready to rally through miles of punishing terrain. This bike can take big hits, accelerate, and change direction all with equal proficiency. It’s seemingly impossible blend of agility, speed, and ability to break tackles is truly miraculous.
