Transition PBJ Youth - The Ultimate Dirt Jumper
Redesigned from the Ground Up
The legendary Transition PBJ returns, fully re-engineered for the next generation of riders. This high-performance dirt jumper has been completely redesigned with a new hydro-formed 6061 aluminum frame, refined geometry, and rider-focused details that elevate every session. Whether you’re hitting the dirt jumps, flowing through the pump track or carving lines at the skate park, the PBJ delivers unmatched precision, balance and control.
Hydro-Formed 6061 Aluminum Frame
The new hydro-formed 6061 aluminum frame gives the PBJ its signature strength and lightweight feel. This advanced manufacturing process allows for sleek, sculpted tubing that keeps the frame stiff, responsive and incredibly durable. The compact rear triangle and low standover height give riders effortless manoeuvrability, perfect for throwing tricks, manuals and whips with confidence.
Geometry for Modern Dirt Jumping
Transition has refined the PBJ’s geometry for today’s riding style—short chainstays for quick acceleration and pump, a balanced reach for control in the air, and a low front end for a responsive, planted feel. It’s an agile dirt jump bike that rewards precision, helping you find flow and speed on every line.
Manitou JUNIT Comp 100mm Fork
The Manitou JUNIT Comp 100mm fork delivers responsive, youth-specific suspension performance. Built around a 34mm chassis, it provides precise damping and smooth control without excess weight. The air spring system allows easy tuning for rider weight and style, ensuring every take-off feels sharp and every landing perfectly composed.
