Bikejoring (pronounced baik-jawr-ing) is a sport where one dog or a team of dogs runs in front of a bike, pulling. Dog bikejoring has its origin from mushing, where dogs pulls the musher on a sled. When bikejoring, your dog is connected to the bike with an elastic line. The line is kept away from your front wheel with a bike antenna. Your dog should wear an ergonomic bikejoring harness designed for this purpose, allowing him/her to move and breathe freely even when pulling.
