Meet the Fire Mountain—where classic Kona engineering meets pure trail-shredding joy. This beast doesn't mess around with its smooth-shifting 8-speed drivetrain, keeping you in the sweet spot whether you're climbing rocky ascents or flying down technical descents.

Need to scrub speed fast? The bombproof mechanical disc brakes deliver stopping power you can trust, every single time. With 100mm of suspension soaking up the bumps and wider 27mm rims wrapped in sturdy rubber, the Fire Mountain transforms sketchy terrain into your personal playground. Confidence isn't just built—it's earned, and this bike makes earning it feel effortless. Size matters, so we've got you covered: grab the nimble 26" wheeled XS for smaller riders, step up to the 27.5" wheel in size S for that perfect middle ground, or go big with 29" wheels in sizes M through XL. No matter your frame, the Fire Mountain is ready to turn your next adventure into a story worth telling.
