As Nicolaisam said above, Banshee Prime meets your criteria, the pre 2017 models in XL are 480mm reach the 2017 models are 484mm, they have a low standover so dont look like a garden gate 🙂
And weight wise mine is 31lbs with heavy tyres(conti baron and mountain king) and a brand x dropper, hope hubs, pikes, slx mostly and clipless pedals, could knock a couple of pounds off if I tried but I cant be bothered.
Also the 2017 have a choice of dropouts allowing all kinds of 29/29+/27.5+ shennanigans.
I’ve got a large so I’m a little biased, have slack bushes and a 2 degree headset to stretch the wheelbase and drop it down to 65 degree, to be honest it was great without but i’ts a superb bike with.
