Ruthless Progression

This totally redesigned P.Series gives riders of all sizes a jumping off point to a life on bikes. The lightweight, but tough alloy frame is designed to take all the hits and keep rolling—across all frame and wheel size options. Our approach to these robust bikes centers around delivering a simple, high-quality platform that's versatile for all riders, and packs in category-first features that make a difference to the rider.

Starting with the durable lightweight alloy frame, the new P.Series stands up to the demands of dirt jump progression. Its cables are internally routed, adding to its sleek presence and tangle-free riding.
