Description of SmarTube H2bike System H2bike is a new patent pending product, by BlueDesert, developed especially to meet hydration needs of bikers while cycling. Common drinking bottles remain by far the preferred hydration solution by bikers. The inconvenience and hassle of carrying a hydration pack on the back while cycling, emphasizes the need for a truly handsfree and safe, bike mounted hydration system. The desire to harness the SmarTube to the benefit of bikers inspired BlueDesert to develop the H2bike bikers hydration kit. H2bike is the outcome of extensive R&D relying on input by professional bikers. The revolutionary MultiFix allows fixing the mouthpiece in the desired vertical and lateral position for optimal hands free accessibility to the biker while cycling. MultiFix serves also as a resting point for the straight SmarTube drinking tube. The SpiralTube and the straight SmarTube may be manually extracted to bring the mouthpiece to the biker's mouth. Once released, it self retracts and reposistions on the MultiFix holder, ready for the next use. H2bike is compatible for use with most mineral water bottles, bike bottles and outdoor bottles like Gatorade, Powerade, SIGG and Nalgene.
