WE HAVE INCORPORATED THE ESSENCE OF OUR KNOWLEDGE AND OUR GENES INTO THE FACTOR 24 TO MAKE IT AN AUTHENTIC MOUNTAIN BIKE – even though it is smaller than most others. Its lightweight frame made from 6061 STEALTH EVO aluminum features our ZERO SUSPENSION system, making it exceptionally powerful – whether going uphill or downhill. Additionally, its agility combined with the 100mm of travel at both the front and rear provides a lot of riding fun. And as your kids grow a bit bigger, the 24" wheels can easily be swapped out for larger 26" wheels, effectively extending the bike's usable lifespan well beyond what is typical in this category.
