The Bike RIG is the ultimate hands-free pressurized water delivery system. The streamline design provides convenient storage for treats and tools, a rear bike light attachment, optional external bulb holder attachment to mount it directly to the bike if desired, and simple attachment to any road or mountain bike directly behind the saddle.
