I just picked up the beginnings of a kayak hauler that used to be a convertible two-wheel kid bike trailer to three-wheeler stroller. It was really well made and features mostly aluminum construction, 20" wheels, leaf sprung frame and locking axle. I think all it's going to need is some closed cell foam padding strategically added to the frame and some type of connector arm from my bike's rack to secure the nose of the kayak. Other people's garbage score that a friend picked up for me.
