I fabricated a rear wheel prop stand , pivots near the axle.
used thinwall steel tube ,freestanding, holds up the loaded bike
where ever I stopped,
rolled the loaded bike back onto it like a motorbike..

Made packing up a breeze as it stood up on soft turf, where the camp was
and Access to both sides was insured.

daily rider is my Koga , they came OEM with a modified Tubus low rider KS
and a Plate for mounting a center prop stand
its planning ahead with the mounting plate that is the important part.

there is another type, uses bosses brazed into the rear of the chainstay,
to mount a KS back there, bolts thru those bosses,

gets done before the paint goes on.
