From trail to park, the Diamondback® Adult Assault Dirt Jumper Mountain Bike can slay jumps on any surface. This dirt jumper is inspired by DF5 Pro Factory Rider Billy Lewis and features an aluminum frame with steel reinforced horizontal BMX dropouts. The FOX front fork and 26" wheels soften your landing on whoops, rollers, and ski jumps.
DISCLAIMER: A bicycle is a complex piece of equipment that must be properly assembled and maintained in order to be ridden safely. We strongly recommend that you consult a professional bicycle mechanic to properly assemble, repair, and maintain the bicycle. DICK'S Sporting Goods will provide free in-store assembly service by a certified technician for any bicycle purchased in our stores or on our website (proof of purchase required). If you choose to assemble the bicycle yourself, DICK'S Sporting Goods will not be held responsible for injuries or damages resulting from improper assembly. Please contact your local store to arrange assembly service.
