Intrigued by your review Rob. I only just got round to nerding out on this bike and I have to say YETI's marketing is genius/laughable depending on where your love of the brand lies.
WE DON’T PARTY UNTIL THE RACE IS OVER. SO WE TOOK OUR TIME TO DESIGN AN e-MTB THE WAY A YETI e-MTB HAS TO BE DESIGNED: READY TO TOE THE LINE AT EWS-E RACES. MEET THE 160E: THE WORLD’S FIRST RACE SPECIFIC e-MTB.

E160E
WHILE EVERYONE ELSE WAS RACING TO MAKE AN E-MTB,
WE WERE MAKING AN E-MTB FOR RACING.
(and they chose to put a Shimano motor in it?) EPIC FAIL!

I KEEP FINDING MINE.

As for sixfinity. Yes it's a clever little extra link that (not too dissimilar to the idea behind infinity link on their SB bikes) allows YETI to design in good AS to the suspension kinematics. But it doesn't actually do anything groundbreaking. The axle path is still an arc around a virtual pivot point just like many other multi link designs (of which, most these days do also generally have very good AS traits).
Their claim that their SIX BAR DESIGN uses all SIX linkages to control axle path is kinda laughable too. Seeing as all FOUR LINKAGES control the axle path of any horst 4-bar or dual LINK VPP and CAN also be tuned just as easily by any savy designer to give good AS and AR curves and values at certain points (ie. Sag)
Have to agree with hobnob about YETI's bearing and frame warranty claims
It does look to have decent geometry. And adjustable leverage curve isn't a bad thing.
