3-SKI SNOWBIKE

摘要

The 3-ski snow bike designs transform bicycles into 3-ski snow bikes that can be used for downhill and cross country snow biking. It consists of a bicycle frame with 1 permanent front ski instead of the front wheel and 2 detachable rear skis on each side. The 2 rear skis provide good snow bike stability while the short front ski allows for easy maneuverability. These 3-ski designs are adaptable to most types of bicycles with pedals and rear wheel of bicycle attached and used to move the 3-ski snow bike cross country, or removed for downhill snow biking. The steering bar in addition to controlling the turns with the front ski can be used to move the 2 rear skis up/down, enabling the snow bike to lean during turns, or the rear skis can move freely for easier control on steep slopes. The 3-ski snow bike also has a breaking mechanisms (brake bar digging into snow), rear shocks for a smooth ride, and ski attachments that easily connect to most downhill ski bindings, so that the rider can change the length and type of rear skis, depending on size, ability, and snow biking terrain.
