Bibe
Bibe is a device at the forefront of cooling technology in a portable application, already with a US patent (a couple more in the works). It is capable of withstanding a lot yet light-weight, easy to use, easy to attach, versatile, affordable and for pretty much any type of weather. Although, realistically if you're cycling in cold weather you probably want a warm drink and not a cold one!
Bibe has launched a multi-purpose portable cooling system designed for bicycles. The system replaces the traditional bicycle bottle cage with one that can transport bottles or cans inside and convert the equipment into a transportable refrigeration system.
