If your riding leans more towards steep, technical descents and bike park laps, the Kona Process G2 153 27.5 is your go-to. Built as the longer-travel sibling to the Process 134, this bike is designed to deliver maximum confidence when things get rough, fast, and unpredictable.

With 153mm rear travel paired to a 160mm fork, the Process 153 offers serious enduro capability while still maintaining a balanced, climb-friendly feel. The 27.5” wheels keep the ride playful and responsive, making it ideal for riders who want a bike that’s as happy throwing shapes as it is smashing through rock gardens.

This is Kona’s “go big” trail bike — a proven platform for riders pushing harder, riding steeper terrain, and demanding more from their bike
