Used For
Trail Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike. Enduro If you’re looking for maximum performance while flying down heavier trails, an enduro bike is for you. These bikes combine ample suspension travel (typically 150mm+) with descent-focused frame geometry and components that allow for reasonably efficient pedaling. -
