Dirt Jump
P.4 is an alloy dirt jump mountain bike (2024), by Specialized. Rider-wise, it fits riders who want a more active, performance-leaning off-road feel, with a sporty, active riding position, while being more at home in gravity-focused bike park riding. On MatchBikes metrics, it scores well for strong speed potential on smoother terrain, a balanced ride feel between comfort and directness, and capable suspension support for rougher terrain. What it gives up slightly is more of a flat-to-rolling terrain bias than a climbing focus and a value score that depends more on priorities than pure price efficiency. Next step: compare this bike with other dirt jump models on MatchBikes.com.
