After searching online and not being satisfied with what's out there I decided to create my own. Still have some modifications to do. Still needs paint but so far I am happy with it. Holds 4 road bikes, just have to place them front, rear, front, rear and I'm thinking about adding a modification to allow for mountain bike tire sizes. Also I have plans to use straps or a type of strapping to secure the bikes more. Lightweight but sturdy, foldable for easy storage and a multi-application rack are my goals. Stay tuned for more.
