Gave bikejoring a shot
My dog (Heeler/Aussie Mix) has always loved running alongside, and usually just ahead of, my bike.
Instead of using a jogging belt and constantly worrying about tangles, I decided to put together a DIY setup.
I used some PVC pipe and zip ties for the initial version. The zip ties are temporary and will eventually be replaced with a proper clamp.
To shape the PVC, I heated it in a pot of boiling water, then bent it around the seat tube using oven mitts. Once it was in the right position, I poured cold water over it to help it cool and hold its shape.
I secured the PVC to the frame with zip ties, tied the leash to the frame, and added another set of zip ties to keep the lead away from the tire.
Took it out for the first ride today and it worked great!
