Here's a rather nervously executed video of me and Mazunte out "bikejoring". Bikejoring means simply hooking up one or more dogs to a bicycle and let it rip.
The biggest challenge in bikejoring is surviving those few seconds between hooking up the dogs and mounting the bicycle. I normally keep one foot on the gangline up until the last second.
Below is my setup, I use an old bicycle tube to add some suspension.
