Unlike the 'Growler City Bike,' which has a built-in beer holster, the 'Growler Cage' turns any bike into a beer bottle-carrying vehicle. This attachment is designed to securely hold glass growlers in place while you motor around the city on your bicycle. The cage is fortified by a stainless steel core and coated in waterproof neoprene that keeps a firm grip on your beer. These neon sheaths are available in a wide range of colors and are replaceable, which is good news for avid bikers.
The Minneapolis-made cages are designed to fit in the place of water bottle cages and integrate sliding mounts to adapt to bikes of any size. This unusual bike accessory combines two activities that shouldn't go together, but in a safe way to assure you are steered clear of trouble on the road.
