ALL ABOUT PUMPS, BUMPS, AND JUMPS.
The PBJ (Pumps, Bumps & Jumps) is our dirt jump specific hardtail with more relaxed and slacked out geometry designed for mountain bikers. The PBJ looks were inspired by old school BMX frames with a taller seat tube for a balanced look. A slacker head angle and lower bottom bracket add stability and increase your confidence whether you hitting a big set of dirt jumps, ripping a pump track or trying that perfect manual.
ULTRA STABLE & LONGER GEOMETRY.
We’ve had a steel dirt jump hardtail in our lineup since day one. No need for 3D renderings or fancy molds, just good old round tubes and clean lines. It’s just one of those timeless iconic bikes that will always have a home at Transition because it represents where we came from. Our PBJ is a pure mountain bikers dirt jumper with slightly more relaxed geometry that makes it blast on Pumps, Bumps and Jumps.
