If your AllMtn 5.0 is the same as my 2016 AllMtn Plus, the kickstand mounting eyelets on the left chainstay are slickly hidden by a black plastic cover (first two photos). I don't remember if the eyelets were threaded, but the backside of the chainstay is molded for the nuts (third pic). My dealer got me a run-of-the mill standard kickstand, and I believe @Ravi Kempaiah correctly referenced 18mm kickstands (though I did not measure mine). The nuts and bolts come with the kickstand. Just make sure you apply some Lock-Tite; otherwise, it will loosen quickly.There are no bolts.
