I constantly read posts warning against mounting a bike rack on the rear bumper. People say they've seen bumpers & bike racks laying on the side of the road. People say they've seen bikes dragging down the road because the bumper twisted. I've been a driver/passenger for over 56 years & I have never seen these things. I have camped for over 40 years and over 10 of those years I've towed an ultralite.
I constantly see bike racks on the back of ultralites & I constantly talk to the owners who constantly say they've never had or seen a problem. I know, someone is going to say "Go ahead & try it bright boy & I'll be the first to laugh when you post that you lost your bikes".
Well I'm going to try it. A 4" square bumper welded to a solid steel frame should be able to take the torque & bouncing of 80lbs of bikes.
I have also talked to numerous dealers who say they have never had a customer say his bumper came off because of a bike rack. From this day forward I will no longer listen to the fear mongers of the world, & if you see a bumper with 2 bikes attached I sure hope they're not mine.

This is the KEY FACTOR, "welded to the frame".
I carry a huge MH tire mounted on the bumper AND I have a bike rack also mounted on the same bumper that I carry very heavy ex-pens on.......10 years and counting and have not lost either one of them! :B
I suspect the the bikes/racks in a ditch are from the owner NOT mounting the bumper rack and/or the bikes properly. And honestly I think the ones you see on the side of the road are from the ladder mounts.
That said:
When I post what I do and suggest these types of mounting racks for a square bumper I am reminded that not all RV's especially TT's and FW's have a welded to the frame square bumper.
Curious how many of you out there have bumpers that are "not" welded to the frame?
