The Springer is a Norwegian invention. Many thousands of Springers have been sold in Norway, Sweden, Germany, Switzerland and the United States since 1987. The Springer is completely galvanized for maximum protection against corrosion. The Springer is a bike attachment that allows you to cycle safely with your dog. The Springer fits any bicycle and allows you to always keep both hands on your handlebars. The heavy duty steel spring is positioned at a low angle so cyclists can keep their balance while simultaneously protecting their dog from traffic, pedals and wheels. The patented safety release frees the dog instantly if he gets caught around a lamp post, for example. K9 corps around the world even use the Springer for their police dogs!
