SnowBike Concept
Concept for Faction Bike Studio 
The aim of this concept was to design a bike that allow bikers to explore snowcovered terrains with ease. The first innovation comes from the tire which have littles holes on it to let the snow go through, which is inspired by snowshoes. This snow-bike also featured an internal gearbox, centralized belt drive, the bike is capable of gathering the required pace and that too, without asking the biker to exert too much effort. Moreover, the centralized belt drive straps itself through a split rear tire.
