We are swopping our motor bikes for push bikes to take with us on our adventure
What types have you come up with ?I am interested to see what you have out there. Did you buy them of the shelf or did you have to have them made. I have looked at a couple but they certainly were not steady enough.
Time is coming close for us to take off. Still heaps to do on the house but the end is near

I went off one day to buy a rack for bikes. I wanted to put it over the spare wheel on the back of the van. Sadly, they told me that this would not work, and sooner or later, I would find the bikes gone- lost to the fact that this was never made to carry anything more than the spare wheel. So, my advice- be ware of what your limitations are.
we had 2 bikes on the back of a 20ft van, mounted back down to the van subframe that supports the 2 spare tyres.
The frame for the bikes was 50MM tube attached to a HEAVY DUTY bike rack. We could see the vibration in the rear camera and it beat itself to almost a bad death.
Anyway we fitted an even heavier frame with 13 mm high tensile bolts and even this proved risky as it would eventually vibrate to death and possibly damage the subframe that supports the rear spare wheels.
The main problem for us was the distance from the van axles to the bike rack as this exacerbated the bumps (we go on dirt "roads") and the vibrations/oscillations.
Hope this is not too techo, but we decided the van was more important and if we took bikes again they would be fold up and in the ute.

Over the years I have read warnings about bike carriers and high frequency vibration causing metal fatigue to parts of tow bars. The same problem would occur if attached elsewhere. Maybe some qualified person might comment.
I've seen bikes hanging high on the back wall of a caravan, on some kind of rack. I wonder would this cause as much vibration as when they are on a bike rack attatched to the rear bumper-bar?
I made my own bike rack after trying 3 different bought types They sit above the spare whee; on a coromal 511 I did however weld extra 50mm supports for the rear bumper The rack i eventully made is similar to one that looks like a motor bike rack where the bikes sit on it rather than suspended They are attached via both wheels supported on carriers then attached at the crossbars to keep them vertical The rack is removable and is simply attached via an upright tube from the spare wheel carrier
This sounds like what we need. Would you mind if you are able to, take a photo for us and put it on the site or email to us. We are suecardwell01@gmail.com
Like you we have looked at quite a few but they were not suitable.

I bought a rack for $5 at a garage sale that goes on the towbar and can fold down to open the tailgate. Haven't used it yet. It is quite heavy and would be a bit of strain on a towbar I would think.
We had a towball mounted, fold down, rack for our 2 bikes before we got van. On van, had a bar built across the A frame, in front of the gas bottles. It went up, across and down - wasn't flat across the A frame. In the middle of it, was a hole to put a tow ball in. We put the bike rack on that, and so carried the bikes between the back of the vehicle and the boot of the van. Worked very well, for years. When we were camped up, and wanted to go riding somewhere a little distance away, could transfer the rack to towball on back of vehicle.
I can't see how the weight of a couple of pushbikes on the rear bumper would be a problem. I've seen rear bumpers carrying generators, motor scooters, outboard motors, fold-up boat trailers, full jerry cans, etc, all much heavier than a couple of treadlies.
