This snow bike is a complete bicycle with front ski instead of a wheel, and 2 rear skis attached between pedals. Pedals with rear wheel provide forward motion and the 2 skis on the sides pivot to provide side support and carving through the snow. Build in brakes are optional. The rear skis are detachable and not included in the price because most downhill skis up to 160cm can be used.
Bike comes with a jagged strap footrest, but can be ordered with pedals. Picture shows solid frame snow bike, but can be ordered with a folding frame for easier transport in the trunk.
