The Instinct has been designed for epic rides and wide-open singletrack. As our most versatile platform, the Instinct thrives on all types of trails, tackling features with the utmost efficiency and responsiveness.

The Instinct has been the go-to bike for riders looking for a bike that does it all, and our most recent design takes that philosophy to the next level. The desire to ride faster and harder than ever is universal amongst riders, and the changes we’ve made to our Instinct take that to heart while maintaining peak efficiency. Updated geometry and frame features mean that the Instinct is versatile and can adapt to meet any demands that you or the trail may have.
