Due to delays in global supply chains, Manufacturer may have replaced some original components with equivalent or higher quality components. In some cases, the bike delivered may differ from the images.

The B-17 combines our acclaimed 120mm MultiTrac rear suspension system with 27.5+ tires for an all-day, all-conditions trail bike ready for the unknown. The large volume tires allow for extra low tire pressure and unheard of grip and control in most every condition for an instant confidence boost at speed, and uncanny climbing abilities to conquer the next ridge. At nearly the same outside diameter as 29” tires, 27.5+ tires offer similar roll over capabilities, but with added float and an even larger tire to ground contact patch to help tame the trail.

The B-17 is our most capable MultiTrac bike, built for the all-day trail rider looking for a playful bike with maximum traction. Plus-sized tires are an instant confidence boost and traction upgrade, sticking to most everything and making it possible to climb and descend sketchy parts of trail that may have required hoofing it before.
