If you go from Your house, to lock up firmly onto something when you get there,
Or any time you stop, to keep the bike from being Stolen, it may be OK without one.

if you get tired of your bike falling over a lot, It may be a good thing..

A rear triangle mounted stand will work when the chainstay/BB area is crowded.
but won't go there if there is a disc brake.

My touring Bike has a KS under the left Lowrider , + the regular one ,
to keep the pannier's weight from pulling the bike over..

and damn easier to pack/unpack a bike not laying on the ground

My recent purchase , a Bike friday has none, but I lock it up when I stop,
so I have began to cope with it not being there, over time.

If I have enough things I can add to a replacement order,
to justify a frameset trade in. I will have A KS mount included ,
probably for an Esge 2 legged one..

The key is having the frame design thinking ahead,
and making a Kickstand mount part of the frame,
before the paint goes on.

My old Stumpie, by now the winter bike is kind of reshaped, by the tube distorting
yielding to the clamping on the KS..
