This isn’t a cool bike, accessory or part but rather a large “bike rack”. I’ve been looking for a small trailer to use as a bike hauler. I was able to make a deal on a slightly used PJ Steel bed trailer. We picked it up on Monday. I haven’t pulled a trailer for years, now I need to learn to back one up again. Anyway I have a couple of racks to use in the bed and bed box that used in my old Mazda truck. I’m thinking I’ll make some old school wooden side racks for it and possibly remove the rear ramp. Here is a before pic and after rough concept sketch.
