After searching online and all kinds of bike racks we settled on transporting bikes
By mounting fork mounts on the dinette bench with cushions off that can be flipped over when not in use. Here is a pick of one, we are going to add more and stagger them as well as put some eye hooks on the rear side to attach bungee cord to extra secure the rear although it is very secure
Also, a quick tip, If you want to mount more than one, with the handlebars at the same end. Rotate the mounts a bit so the handlebars are at an angle to the frame, Then they won't interfere with each other.
