I salvaged an old bicycle rack to attach to the front bumper of the bus today. I have been transporting my bikes in the cabin of the bus and they are a major PITA to get in the front door and up the steps. Once inside, they are difficult to secure so they won't damage the interior. This was a cheap solution. Would have prefered them on the back, but my trunk is there and has two doors that open "barn door" style outward. The bikes should hang free of blocking the headlights and turn signals.
Painted them gold and brown to somewhat match the colors of the bus once they are installed. I think I will also put a cross brace between the two uprights for a little more strength and cut down on movement.
