With bike-jor, ski-jor and scooter-joring sports the dog(s) are attached to the bike by bungee lead and harness. They run and pull whatever they're attached to and the rider pedals or assists in propelling the vehicle forward. Everyone that does this sport will ultimately crash at some point. On a less competitive level it's called 'Urban mushing'. 
I trained my dog to do urban mushing and we've been doing it for just over a year now. Being a 'big brain' shepherd dog that runs with me, rather than running off from me, he is able to 'free run' with me in safe country areas. I call this eJoring. I find it much more fun than simply walking the doggy and there's less crashing.
