I'm going to pickup my new trailer tomorrow and have been brainstorming how to haul 3 bikes. I'd like to keep the floor open for other things and don't want to put a bunch of holes in the floor. My plan is to mount a 2x4 across the trailer 6-8 " above the handle bars, and using tie downs to hold the bikes up putting enough pressure on the bikes to keep from falling but not lift the wheel off. I realize the bikes may rock back and forth a few inches but i don't think it's a big deal. The 2x4 will be removable as I'll have a bracket for it to drop into on each side of the trailer. for 3 bikes I'll use 2 2x4 and put the 3rd bike in backwards. If this works a guy could put some plywood across the 2x's and have a shelf for light items. The trailer is a 6x12. Am i crazy or does this sound workable????
