Half dirt bike, half snowmobile, Timbersled brings the thrill of off-road motorcycling to the snowy winter landscape. The Mountain Horse conversion kit comes with all the parts needed to attach onto most major dirt bikes. Roughly 200 lbs lighter than a traditional snowmobile, the Snowbike allows for much greater maneuverability and control.   As the video above shows, Snowbikes can slalom between trees with ease and bound up some seriously steep inclines. Although personally, if I never have to hear that M.I.A. song again in my life it will be too soon!
