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. Downhill For bike park days and shuttle laps, there’s nothing like a downhill (DH) bike. Designed to tackle the roughest trails at high speeds, these bikes have long suspension travel (typically 170mm+), huge brakes, and unreal descending capabilities. DH bikes are not as suitable for tight trails or climbing.
