Instinct Powerplay C90 Shimano
Rocky Mountain
Trail
Instinct Powerplay C90 Shimano is a carbon electric trail mountain bike (2023), by Rocky Mountain, from the Instinct lineup. It suits riders who want a more active, performance-leaning off-road feel, with a setup that gives you a sporty, active riding position, with a surface profile that is well suited to natural trails and mixed off-road terrain. Metric-wise, it stands out for a comfort-leaning ride feel over longer rides, capable suspension support for rougher terrain, and balanced, versatile speed for everyday riding. The main limitation versus more focused builds is a value score that depends more on priorities than pure price efficiency and battery range that is better for shorter daily use than long all-day outings.
