So glad of your input on a Ryker pull behind trailer. I’m very familiar with the Unigo single wheel trailer as I have pulled with my Harley and BMW Adventure. I think maybe the Unigo hitch system is over kill as it is designed to lean with a motorcycle which is not needed on a Ryker IMHO. A simple hitch would suffice as there is minimal lean, as similar to a car. I think a fabricator could come up with a frame mounted hitch system. I hope we get some more ideas on this. cueman
